1. Scope of Procedure This Procedure is applicable to gas installations, generally located within buildings, downstream of the building additional emergency control valve (AECV). The gas safety management system for the University gas network, generally located below ground except for the gas governor installations, upstream of a building AECV and downstream of the National Grid network supply point emergency control valve (ECV) is covered by the Keele University Gas Safety Case. The procedure has been compiled to inform and designed to achieve continuous improvements to health and safety performance relating to Gas Safety with continuous monitoring of standards of work, certification and plant performance. The procedure is aligned with the Estates Strategy and the University s strategic plan which commits to the management and maintenance of its assets which includes gas installations and appliances https://www.keele.ac.uk/estates/estatespolicystrategy/estatesstrategy/keele%20university %20Estates%20Strategy%202011-2015%20Website%20Final.pdf https://www.keele.ac.uk/aboutus/strategicplan/ The procedure is also aligned to the University s Health and Safety Policy and its desire to set safety standards which include all aspects of gas safety https://www.keele.ac.uk/media/keeleuniversity/healthandsafety/docs/final%20h%20%20s %20Policy%20Statement%202015-16-%20VC.pdf Keele University is responsible for gas safety related activities in Domestic, Catering and Commercial type Natural Gas Installations with a limited number of LPG Installations on the University estate properties. The Estates and Development Directorate is responsible for ensuring that all properties including some domestic dwellings with gas installations are safe and compliant with respect to the Gas Safety (Installation and Use) Regulations. This document outlines the extent to which Keele University has put in place arrangements that will ensure so far as is reasonably practicable, the safety of staff when working on gas appliances and installations, downstream of the Emergency Control Valve. Procedures are also in place to ensure that all contractors employed on gas work comply with safe working practices. Keele University property portfolio is extensive as it covers Medical, Pharmaceutical and Science Schools, Halls of Residence, Faculty Offices, Catering, Sports Hall and Administrative Amenities. The Gas Safety Management System will apply to all sites owned or managed by 1

Keele University however there are exclusions detailed in section 6 organisational responsibilities which details responsibilities for commercial tenants, staff housing tenants, medical and some bottled gases. Fixed or portable sources of LPG and any temporary heating / catering / process imported for use on the site shall be covered. The University has a combination of private natural gas networks and gas incoming supplies that are the responsibility of National Grid and therefore outside of the remit of this management system. 2. Procedure Statement The responsibility of Keele University, in relation to gas safety, is to ensure all gas equipment installed and used within all University properties are installed and maintained by competent persons and is safe to use and present no harm to any person. Keele University will gain access to all properties it is responsible for at least once in every twelve month period to: Ensure the safety of persons through regular safety inspections and maintenance of all fixed gas fuel-burning equipment. Inspect and test gas supplies and flue installations for integrity and safety. Ensure that residences own gas appliances are correctly installed and safe to use. Ensure the safety of persons through the regular maintenance of smoke alarms. Ensure the safety of persons deemed to be at risk by regular maintenance of carbon monoxide alarms. For all non-domestic gas pipework installations a programme of tightness testing will be undertaken ensuring no installation is left untested for more than three years. Where a report is received that gas equipment is not operating satisfactorily a risk management process will be adopted and a suitably qualified operative will attend site to initially make safe and then carry out remedial actions as soon as practicable. The University will ensure that all users of gas fuelled equipment either residential or educational are made aware of the safe operation of such equipment. 2

3. Legislation and Guidance Under the requirements set out in the Gas Safety (Installation and Use) Regulations 1998, Keele University is required to ensure that all gas appliances, flues and gas pipework are checked regularly. A Gas Safe registered gas engineer must carry out the safety checks and a record of each safety check needs to be held by the University and the resident or responsible person for the premises. The University has a responsibility for ensuring that access is gained to each property and also that it can be demonstrated that the University has made reasonable efforts to verify that the checks are being properly carried out. The University will also be responsible for overseeing the activities of any contractor employed to install, service, or maintain any gas pipework or appliances contained within or supplying University properties. The Gas Safety Management System is designed to ensure that Keele University fully discharges the responsibilities and duties imposed by the regulations: Keele University is not defined as a Registered Social Landlord but has accepted a duty under the Gas Safety (Installation & Use) Regulations 1998 to maintain, in a safe condition, all gas fittings and flues, owned by the landlord, in all of its rented / managed properties. (Regulation 36). The duty involves a check for safety of all owned appliances, flues and pipework every 12 months and, in addition, a responsibility for the maintenance of every owned fixed gas appliance in accordance with the appliance manufacturers servicing instructions. Keele University in its statutory undertaking as a landlord and operator of public buildings additionally carries a duty of care under the Health & Safety at Work Act 1974 to discharge its responsibilities in a safe manner. This duty extends to the maintenance of smoke alarms and where fitted and carbon monoxide alarms. The failure of Keele University to gain access to carry out essential safety checks may result in staff, residents and members of the public being placed in danger. Failure to carry out essential safety checks, if it is proved that all reasonable and practicable steps have not been taken to gain access may result in criminal proceedings being taken against Keele University and its responsible officers. 4. Rationale for Procedure The Keele University Procedure in relation to all works dealing with gas supply, equipment, smoke and carbon monoxide alarm installations identifying the University s commitment to taking all practicable steps to comply with the legal duties imposed onto them by the Gas Safety (Installation & Use) Regulations 1998 and the Health and Safety at Work etc., Act 1974 in relation to gas fuelled equipment, smoke and carbon monoxide alarm installations. 3

Appendix 3 - Qualifications & Training of Employees & Contractors Purpose This procedure describes the methods used and documentation utilised in ensuring that any person with responsibility for gas safety issues or gas work carried out on properties for which Keele University Directorate of Estates and Development has responsibility, is carried out by gas operatives who are suitably qualified, conversant with current requirements and deemed competent in those areas of gas work they undertake and registered as a class of person (currently Gas Safe). The procedure will also ensure that Keele University staffs who are not gas qualified will undertake suitable training events to show their understanding of current legislation and standards affecting gas safety. Scope The Accredited Certification Scheme (ACS) system contains competence assessments for all mainstream work involving Natural Gas or Liquefied Petroleum Gases. Some elements of more specialised work are covered by The Approved Code of Practice (ACoP) but the only existing route for Gas operatives to demonstrate continued competence for mainstream work is through ACS qualifications. All Gas Safe registered gas operatives must be re-assessed on their professed competencies at a maximum of 5 yearly intervals. For the purposes of this procedure the obligations and standards to be applied in determining and maintaining competence will apply to all gas operatives. All ACS qualifications will need to be current, valid, and supported by ongoing evidence of maintaining knowledge with changes in law, technology and safe working practice during the 5 yearly renewal periods of ACS qualifications. DLO technicians who are not gas qualified and outside the scope of this procedure can undertake some normal day to day activities which are excluded from the requirement for ACS competence. This can include but is not limited too; Connecting or disconnecting bayonet fittings or other self-clean connections for the purpose of cleaning the space a gas appliance normally occupies Operation of laboratory equipment such as Bunsen burners Changing of bottled gas cylinders Relighting of pilot lights or operation of appliances 21

Procedure An ACS competence matrix will be held on file by Keele University Estates and Development Maintenance Department. The competence matrix will identify the necessary ACS competencies required for contractors to work on the types of gas systems and appliances within Keele University premises for which the Estates and Development Department has responsibility. The matrix will be subject to annual review or as required by changes to ACS competency requirements. All Contractors must provide a current and valid copy of their GAS SAFE registration certificate as part of the Keele University Sub Contrators Declaration Form - Appendix 17 Contractors will supply the identity of any operatives that will / may undertake work on Keele University gas systems and provide copies of individuals relevant and current ACS certificates and Gas Safe Registration Cards also as part of the submission of the Keele University Sub Contrators Declaration Form - Appendix 17 Any contractor will assume responsibility for vetting any sub-contractors and forwarding their details to the Authorised Gas Safe Engineer.

Review The University Gas Consultants will update these procedures as new equipment is installed within the University estate. It shall be the responsibility of the Senior Operations Manager, Operations Manager, and Authorised Gas Safe Engineer via the relevant project manager, or other representatives, to inform the Consultant of additions to the university gas equipment stock. The operational procedures will be formally reviewed annually. 39

Appendix 5 - Design Guidance Purpose This appendix describes Keele University Procedure in relation to the design, installation commissioning and handover of new installations containing gas and gas fuelled equipment. This appendix highlights the commitment of Keele University to ensure that all new works are fit for purpose and in accordance with all relevant Legislation and standards in force at the time of the installation. Note that the gas safety management system for the University gas network, generally located below ground except for gas governor installations, upstream of a building AECV and downstream of the National Grid network supply point ECV is covered by the University Gas Safety Case. The adopted standards for the University Gas Network are : IGEM/TD/3 Gas Mains IGEM/TD/4 Gas Services IGEM/TD/13 Gas Governor Installations IGEM SR25 Hazardous areas Responsibilities It is the responsibility of the Project Manager of a particular contract to ensure this and all other appendices of the gas management system are adhered to. The Project Manager will convene regular progress meetings to review the project status and identify any actions necessary to deliver the design management plan. Gas systems must be designed, installed and inspected by competent people. All gas supply systems must be based on nationally accepted standards and competent persons used to implement good design practices with respect to mechanical and process design. Scope This appendix applies to all Natural Gas installations not exceeding 25mb operating pressure and LPG fixed tank installations not exceeding 37mb operating pressure from the Emergency Control Valve (ECV) to the appliance installation, including chimney and ventilation requirements. It is inclusive of all pipework, valves and controls. It covers the design, construction and installation of gas systems but also applies during operation, decommissioning and demolition. For installations which include pressures above 25mb, the following guidance should be consulted: 40

For pipework IGEM/UP/2 (up to 60 bar) For meters and regulators IGEM/GM/8 For tightness testing IGEM/UP/1 Procedure The Procedure of Keele University is to ensure that all gas installations are designed in accordance with the applicable standards in force at the time of installation, whether designed in house or by an external consultant. Keele University will ensure that all materials and equipment shall be in accordance with the relevant standards and are fit for purpose, no equipment shall be used that does not bear reference that it conforms to an approved type; for example CE marked. Plant, appliances and equipment must be delivered to site only when required for installation. Prior delivery shall only be by arrangement. Installations shall only be installed by approved operatives, employed by a Gas Safe Registered Company and who have satisfied the Project Manager of their competence All new gas pipework or extensions shall be strength tested, tightness tested and purged by Gas Safe Registered persons and the documentation forwarded to the Project Manager All new gas equipment shall be commissioned by a Gas Safe Registered persons and the commissioning documentation forwarded to the Project Manager The University shall ensure that all new installations have been subject to sign off by a competent auditor Procedures Introduction During design the operation of each pipe installation needs to be clearly understood not only under normal considerations but also those conditions arising during start up, shutdown and as a result of process upsets. The designer should consider procedures to ensure that phenomena known to cause problems in piping systems are allowed for in the mechanical design or designed out where practicable. Guidance follows industry documents published by the; Institution of Gas Engineers and Managers IGEM House 26-28 High Street Kegworth Derbyshire DE74 2DA Tel: 0844 375 4436 Fax: 01509 678198 Email: general@igem.org.uk 41

Where appropriate reference is also made to guidance in British Standards or other supporting documents. The following documents can provide guidance in gas installation design, risk assessments and management procedures. Installations within teaching areas shall be designed and installed in accordance with: IGEM/UP/11 Edition 2 Communication 1744 Gas: Installations for educational establishments. The standard covers the design, installation, operation and maintenance of gas pipework, systems and appliances used for teaching purposes in educational establishments, including schools; colleges; universities and training Development. The standard applies to the installation, alteration, replacement, servicing and maintenance of new and existing pipework and appliances. It assumes general compliance with other relevant Standards such as IGEM/UP/2, IGE/UP/1 (or IGE/UP1A or IGE/UP/1B as appropriate) BS: 6891, BS: 6172, and BS: 6173 and provides additional requirements as considered necessary in educational establishments. The standard does not cover gas installations in an individual domestic dwelling integral with an educational establishment. However, the installation of domestic gas appliances in an educational establishment itself is covered. Guidance on operational issues for gas systems is provided by, Gas installations for the management and staff within educational establishments. IGEM/UP/1101 Communication 1745. This guidance is aimed at governors, head teachers, bursars, teaching staff, technicians, premises officers and maintenance staff within educational establishments. It covers responsibilities for legal compliance and what systems and procedures they must have in place to ensure that the exercise of professional judgement by responsible engineers/persons is subject to appropriate monitoring and review. Risk Assessment Techniques Risk assessments are required under the provisions of; The Health & Safety at Work Act which requires employers to ensure the health and safety and welfare of their employees The Management of Health & Safety at Work Regulations which require that a suitable and sufficient assessment of risks be made, and that appropriate measures are taken to provide a safe method of work and The Construction (Design and Management) Regulations 2015 that place specific duties on clients, designers and contractors regardless of the time taken or the number of people involved Gas industry guidance on risk assessments can be found in; IGEM/G7Communication 1655 Risk Assessment techniques. The recommendations describe risk assessment techniques used in the gas industry but which are applicable elsewhere. 42

The recommendations embrace the following types of assessment: hazard identification (HAZID) hazard and operability study (HAZOP) risk evaluation simple risk assessment quantified risk assessment probability modelling failure data collection and analysis consequence analysis The recommendations do not provide comprehensive guidance but, rather explain in general terms what is involved, give an indication of who might be expected to carry out assessments and provide information for engineers and managers on where more detailed guidance can be found. Hazardous Areas When giving consideration to hazardous areas for Natural Gas installations downstream of primary meter installations guidance can be found in IGEM/UP/16 Edition 1 Communication 1756. This standard covers gas appliances including appliance connections with an operating pressure not exceeding 2 bar installed downstream of the Emergency Control. It may also apply to parts of common pipework within multi-occupancy domestic premises; for example between pipe risers downstream of the meter installation and also for central boiler plant. The following is not covered by the standard: Installation pipework downstream of the ECV within a domestic dwelling Compressor installations (see IGEM/UP/6 and IGEM/SR/25) Engines and gas turbines (see IGE/UP/3, IGE/UP/9 and IGEM/SR/25 Any part of a meter installation (see IGEM/GM/7B and IGEM/GM/G8) Gas Pipework: Gas Pipework Design Any new or replacement pipework intended to convey gas shall be designed in accordance with all current standards in place at the time. For design guidance on gas installation pipework, boosters and compressors on industrial and commercial premises reference can be made to: IGEM/UP/2 Edition 3 Communication 1771. This standard applies to the design of installation pipework downstream of any plant isolation valve that is not appliance pipework on industrial and commercial premises. The standard deals with the design, installation, operation and 43

maintenance of pipework including selection of materials and components and applies for Maximum Operating Pressures (MOP) not exceeding 60bar on commercial premises. The standard considers specifically pipework of steel, stainless steel including corrugated stainless steel tubing (CSST), copper and polyethylene (PE). The installation will be designed to cover the general principles of gas system design including, pipe sizing, pressure losses, protection, pipe routing and supporting, operational demands, isolation and industry applications. Calculations and a pipe line drawing will be produced showing pipe routes and all emergency control valves; section isolation valves primary and secondary meter positions. The designer will ensure that the primary meter has the capacity to supply the maximum duty of the installation and any future extension. The required number of valves will be provided at various locations in the gas supply, for emergency purposes, section isolation, appliance isolation, flow trimming, burner isolation and meter control. Valves may be manually operated or automatic. Additional Emergency Controls which are manually operated shall be clearly marked with ON / OFF directions and must be readily accessible. The operating lever or hand wheel must be securely fixed. In pipework less than 50mm bore a plug or ball valve is advised, and for 50mm and above a double seal gate-valve is recommended. In areas where there is a high risk of vandalism or risk of a valve being inadvertently left open (i.e. kitchens, laboratories and workshops) Automatic Isolation Valves may be considered. (AIV s). When an AIV is selected it is vital to ensure that when re- instating a supply following valve closure that gas cannot inadvertently escape from an open control or unsupervised burner. If the risk exists then the AIV system must be either self-proving or require manual intervention together with the provision of a clear warning/instruction notice detailing re-instatement procedure. The requirement to colour code installation pipework in commercial properties can be found in BS 1710 British standard specification for Identification of pipelines and services. For gas installation in flats and other multi-dwelling buildings refer to IGE/G/5 Communication 1712 which covers the design, installation, operation and maintenance of gas supplies to and installations within the dwellings themselves. This embraces buildings containing both commercial properties such as shops and offices and individual dwellings. Domestic buildings shall have their gas installation pipework designed with reference to BS:6891:2005+A2 :2008 incorporating Corrigendum No1 which offers guidance on the installation of low pressure gas pipework of up to 35mm in domestic premises for 2nd family gases. This standard specifies design parameters, materials and methods of installing pipe, in sizes not exceeding 32mm for steel and DN 32 for corrugated stainless steel or DN 35 for copper from the meter to appliances in domestic dwellings at a nominal operating pressure of 21mb. 44

Gas Pipework Installation Prior to commencement of the installation a full programme of work will be produced along with any site specific risk assessments. A permit for hot works shall be attained if soldering or welding of pipework is to be undertaken. A point of work risk assessment shall be completed to assess any risk from asbestos containing materials and any asbestos registers must be consulted before work commences. Materials shall be delivered to site at the time of installation, should delivery be required prior to installation provision for storage will be agreed with the University site staff. All operatives undertaking installation of the gas pipework will ensure that the design is complied with, in all aspects. All operatives will be named on the company Gas Safe Register and will be competent to undertake the work being performed. Pipes shall be installed in accordance with the requirements of IGEM/UP/2 Edition 3 specifically with regard to jointing for example steel pipes above 50mm diameter shall be welded, press-fit joints may be used provided they are approved for gas. Press-fit jointing is suitable for stainless steel to 100mm and copper to 108mm with a MOP of 100 mbar. Pipes shall not be installed within unventilated voids and any voids containing gas shall be preferably vented to outside air. Pipe supports shall be suitable for installation and suitably fixed to the building structure Continual inspection and monitoring will be necessary during construction and pipework installation process to identify any sections that may be contained in ducts or voids are accessible for future inspection Pipework may need to be purged of air or fuel during commissioning or decommissioning procedures. Purging must be controlled and procedures may vary with lighter than air gases (NG) or heavier than air gases (LPG). Guidance is given on the calculation of flow rates and purge volumes and planning and supervision of purge procedures Strength test, tightness test certificates and written purge procedures need to be submitted at commissioning stage before any appliances are put into use and should be included in the Health and Safety file Gas Pipework Testing Commissioning procedures should be in place to ensure that installed pipework is inspected before use to identify any design faults that may have been introduced at the construction stage and confirm suitability for use. Following installation, all new and extensions to the gas pipework shall be strength tested, tightness tested and purged in accordance to the requirements of IGEM/UP/1, IGEM/UP/1A or IGEM/UP/1B as appropriate. The calculations required for testing and purging the installation shall be produced by the contractor and stored for future reference. A site specific method statement shall be produced which will be adhered to by all operatives undertaking the test. The required number of operatives shall be present during the test and 45

purge procedure, all operatives involved with the test shall hold relevant competencies and copies of certificates produced prior to testing. Prior to applying gas to new and extensions, a strength test shall be applied using air or inert gas at a pressure in excess of Maximum Incidental Pressure (MIP) for the installations. Any exclusion zone shall be identified and applied where necessary. The University shall, if deem necessary, request to witness the tests where deemed appropriate. All new and extensions to the gas installation pipework shall then be subject to a tightness test at Operating Pressure (OP) to ensure no escape is present in excess of the maximum permitted leak rate. Pressure tests must be carried out to written procedures to confirm adequate containment at process conditions. Test duration, test pressures and test gauge selection will depend on the pipe size and volume of pipework under test and may vary therefore with individual installations. Following a successful tightness test the gas installation shall be purged to ensure no air or inert gas is present. Fully documented test and purge certificates shall be produced and issued to the University following a successful commissioning process. The volumes and diameters of the pipework under test will determine the test period, type of gauge to be used and permitted leakage rates. Gas Test Certificates will therefore vary and test results need to be compared to the volume and diameter of pipework under test. Guidance can be found in IGEM documents previously stated to determine test methods including test periods, gauge types and permitted leakage rates. Testing of pipework of any diameter will apply in the following circumstances: New pipework Alteration to, replacement of re-use of, or uprating (for example increasing Operating Pressure) existing pipework. New extensions to existing pipework Prior to any work on existing pipework Where there is a known or suspected gas leak in pipework Where there has been a complete loss of pressure for any reason Routine testing of existing pipework Immediately before purging pipework (except when taking pipework permanently out of service) Gas Pipework Purging Purging of gas pipework must only be carried out by competent persons. Purging is a controlled process and a risk assessment is required prior to carrying out the work. A written procedure must be completed detailing the steps and sequence to follow in releasing gas to atmosphere or 46

introducing gas for the first time. Sufficient personnel must be on hand to enable the purge to progress smoothly. Where the purge entry point is remote from or out of site of the purge vent then the use of safe certified communication equipment is required. Planning of the purge should include details of: The number of operatives required to monitor the purge Whether the pipework is part of a ring system, in which case the pipework system may need to be sectioned of at appropriate points to achieve a successful purge If there is likely to be any cutting and welding required, it is preferable that a written procedure is prepared, with permits to work issued Suitable plans of the installation made available and checked for accuracy Pipework surveyed to ensure it is in a safe condition and where necessary defects remedied prior to purging. No purge must take place without a tightness test and pipe survey being undertaken first to establish gas tightness and the availability of purge points and any valve or regulator on the system that may be affected by the purge and need by-passing or removal. Disconnection or spading may be needed to prevent the ingress of a purge gas into the gas suppliers main Purge flow rates need to be calculated and the purge hoses must be of adequate size to handle the purge volume. Purge gas mediums may involve compressed air or bottled nitrogen. Equipment must be regulated. Purging pressures should not exceed the maximum operating pressure (MOP) of the installation Note: If nitrogen is used as the purge gas used this is an asphyxiate gas and the survey must identify occupied areas such as laboratories or storerooms etc which may be in use and can be considered hazardous areas in the event of a leak occurring and must be closed and access controlled during the purge process. Nitrogen purging is generally no longer required. Vent stacks should be positioned away from buildings and electrical equipment the operation of which could cause a spark and consequent explosion. Consideration needs to be given to wind direction when venting to atmosphere and the erection of barriers and warning signs (i.e. No Smoking signs) around the vent stack area. The vent stack should be placed in an open area where the released gas cannot return into the building. The flare/vent stack should be a minimum of 2.5m high, placed at a point 5m away and downwind from any ignition source and controlled by a full bore control valve. Purge volumes, purge vent gas pipe sizes, vent stack sizes and purge flow rates must be calculated and measured. 47

Purging principles and calculations can be found in: IGE/UP/1 or IGE/UP/1A Gas Meters: Gas Meter Design Consultation will be carried out at the initial stages of building design and planning for the designer / contractor to ensure that the proposed meter installation is capable of providing a gas supply adequate for the immediate needs of the proposed gas system and appliances.

Gas Meter Maintenance All gas meters must be inspected to protect against vandalism or corrosion. A maintenance regime will be implemented which should be reviewed periodically to ensure that maintenance is being applied effectively. Plant history will form a major part of the data required to justify making any changes to existing maintenance practices. Design and Installation of Gas Fuelled Equipment No person shall install a gas appliance unless it can be used without constituting a danger to any person. (Gas Safety (Installation and Use) Regulations 1998 All gas appliances shall be installed by persons employed by Gas Safe Registered company and are competent to do so and who hold the relevant qualifications All appliances shall be installed in accordance with the manufacturer s instructions provided to accompany the appliance or appropriate standards No appliance shall be installed without there being at the inlet to it a suitable means of the shutting off of gas to the appliance unless this is not reasonably practicable. This not only allows for tightness testing of installation pipework but allows the appliance to be disconnected in case of emergency or service activities. Gas Equipment Installation checks should ensure that: A sufficient permanent supply of air (whether by natural or mechanical means) is available for the safe combustion of gas Permanent ventilation openings are not blocked or obstructed The room or space where the appliance is located is adequately ventilated There are adequate and suitable means for the removal of products of combustion The operating pressure and/or heat input of the appliance is correct Appropriate operational tests are carried out for the appliance A visual check is made of the flame picture (i.e. appearance), or a measurement is made of combustion performance where necessary The appliance and associated gas fittings function safely, e.g. safety devices including flame protection, vitiation devices, and fan proving systems operate satisfactorily The gas tightness of the appliance is satisfactory The appliance is physically stable, securely fitted and properly connected to other fittings The appropriate CO/CO² checks are concluded where applicable including on condensing boiler plant 50

Gas Equipment Fluing and Ventilation Larger commercial (and industrial) appliances often have purpose designed chimney systems. The appliance manufacturer s instructions need to be followed when installing, servicing and maintaining such systems. The instructions may well stipulate a particular commissioning procedure to be followed. Reference should also be made to appropriate standards. All appliances must have adequate chimney and ventilation provision. For the installation of flued gas appliances reference must be made to the manufacturer s instructions and/or the Utilization Procedures IGE/UP/10 Edition 4 Communication 1784 The scope of these procedures apply to the chimney and ventilation requirements for open flued and room sealed appliances in excess of 70kW heat input but not exceeding 20 MW including: hot water boilers of net heat input exceeding 70 kw steam boilers thermal fluid heaters storage water heaters of net heat input exceeding 70 kw warm air heaters of net heat input exceeding 54 kw radiant heaters The procedures do not apply to flueless heaters such as radiant heating and direct fired warm air heaters (see BS 6896 or BS 6230) or applications within process plant such as ovens, kilns and furnaces (See IGE/UP/12) although certain procedures may be of relevance.
