Install this furnace only in a location and position as spe-cified in the “Location” section of these instructions.3. Provide adequate combustion and ventilation air to thefurnace space as specified in “Air for Combustion andVentilation” section.4. Combustion products must be discharged outdoors. Con-nect this furnace to an approved vent system only, as spe-cified in the “Venting” section of these instructions.5. Never test for gas leaks with an open flame. Use a com-mercially available soap solution made specifically for thedetection of leaks to check all connections, as specified inthe “Gas Piping” section.6. Always install furnace to operate within the furnace’s in-tended temperature--rise range with a duct system whichhas an external static pressure within the allowable range,as specified in the “Start--Up, Adjustments, and SafetyCheck” section. See furnace rating plate.7. When a furnace is installed so that supply ducts carry aircirculated by the furnace to areas outside the space con-taining the furnace, the return air shall also be handled byduct(s) sealed to the furnace casing and terminating out-side the space containing the furnace. See “Air Ducts” sec-tion.8. A gas--fired furnace for installation in a residential garagemust be installed as specified in the warning box in the“Location” section.9. The furnace may be used for construction heat providedthat the furnace installation and operation complies withthe first CAUTION in the LOCATION section of these in-structions.10. These Multipoise Gas--Fired Furnaces are CSA (formerlyA.G.A. and C.G.A.) design--certified for use with naturaland propane gases (see furnace rating plate) and for install-ation in alcoves, attics, basements, closets, utility rooms,crawlspaces, and garages. The furnace is factory--shippedfor use with natural gas. A CSA (A.G.A. and C.G.A.) lis-ted accessory gas conversion kit is required to convert fur-nace for use with propane gas.11. See Fig. 1 for required clearances to combustible construc-tion.12. Maintain a 1--in. (25 mm) clearance from combustible ma-terials to supply air ductwork for a distance of 36 in. (914mm) horizontally from the furnace. See NFPA 90B or loc-al code for further requirements.13. These furnaces SHALL NOT be installed directly on car-peting, tile, or any other combustible material other thanwood flooring.
