High Altitude Derate NOTE - Units may be installed at altitudes up to 0,000 ft. At altitudes above 450 ft. the unit must be derated to match the manifold pressure information shown below. Units installed at altitudes of 450 to 0,000 ft. require a pressure switch change. Units installed at altitudes of 750 to 0,000 ft. require an orifice change. See the Gas Heat Accessories table for ordering information. NOTE - This is the only permissible derate for these units. NOTE - In Canada, certification for installations at elevations over 4500 feet is the jurisdiction of local authorities. Input All Sizes Manifold Pressure in. w.g.

Natural Gas and Propane Installation Code. NOTE In the U.S. flue sizing must conform to the methods outlined in the current National Fuel Gas Code (NFPA 54/ ANSI-Z223.) or applicable provisions of local building codes. In Canada flue sizing must conform to the methods outlined in National Standard of Canada CAN/CSA-B49.. Allow proper clearances to accommodate condensate trap and vent pipe installation. 2 Do not install the upflow furnace directly on carpeting, tile, or other combustible materials other than wood flooring. Counterflow furnaces may be installed on a combustible wood floor if an optional combustible flooring base is installed between the furnace and the combustible floor.
Dimensions - inches (mm) Upflow NOTE - 20C and 20D size units that require air volumes over 800 cfm must have one of the following:. Single side return air with transition, to accommodate 20 x 25 x in. cleanable air filter. Required to maintain proper air velocity. 2. Single side return air with Optional Return Air Base 3. Bottom return air. 4. Return air from both sides. 5. Bottom and one side return air. See Blower Performance Tables for additional information. 2 Optional Side Return Air Filter Kit is not for use with the Optional Return Air Base.
