This furnace complies with American National Standard and National Standard of Canada for Gas Fired Central
Furnaces, ANSI Z21.47 ?
Before installing this furnace, make sure you know all applicable codes. Be sure to consult local authorities having jurisdiction over furnaces for information on electrical wiring, gas piping and venting. The installation of this furnace must conform with local building codes or in the absence of local codes, with ANSI Z223.1, National Fuel Gas Code or CAN/CGA B149, Canadian Installation Codes.

SECTION 3. DETERMINING BEST FURNACE LOCATION
You may install this upflow furnace in an alcove, attic, basement, closet, garage or utility room. Do not install furnace in an area subject to freezing temperatures.
This furnace operates best when
WARNING: Do not install furnace in any other position other than upflow. Doing so could cause heat exchanger blockage and damage to heat exchanger.
Select a location that meets all requirements described in this manual for the following:
??Safety
??Minimum Clearances
??Combustion and Ventilation Air
??Venting
??Duct System
??Gas Piping
??Electrical Wiring
Locate furnace as near to the center of the air distribution system as possible.
Provide ample space for servicing and cleaning. Location must allow 30 inches minimum front clearance for service.
WARNING: Some insulating materials are combustible. When a furnace is installed in an attic or other insulated space, keep all insulating materials at least 12 inches away from furnace and combustion air inlet. Failure to do so could cause a fire.
You may install furnace on
WARNING: Do not install furnace on carpeting, tile or other combustible material except wood flooring.
Doing so could cause a fire.
Install furnace so all electrical components are protected from water.
Level furnace from front to back and from left to right within 1/4 inch. Furnace must be installed level for proper
condensate drainage. Furnace will not operate if condensate does not drain.
When furnace is located within the heated space, exhaust fans can adversely affect its operation. Exhaust fans in kitchen, bathrooms, clothes dryers or anywhere within heated space, increase combustion air requirements of
Sufficient air must be provided to ensure there will not be a negative pressure in furnace room or space. In addition, there must be a positive seal between furnace and return air duct to avoid pulling air from burner area.
When a cooling unit is installed with this furnace, the furnace must be installed parallel with or on the upstream side of the cooling unit to avoid condensation in furnace heat exchanger. With a parallel flow arrangement, the dampers or other means used to control flow of air must be adequate to prevent chilled air from entering the furnace and, if manually operated, must be provided with a means to prevent operation of either unit unless damper is in the full heat or cool position.
When furnace is in a residential garage, it must be installed so that pilot and main burners are located no less than 18 inches above the floor. Also, furnace should be protected from physical damage by vehicles.
When furnace is in a public garage, airplane hanger, or other building having hazardous atmosphere, install unit in accordance with recommended good practice requirements of the National Fire Protection Association, Inc. Consult local code authorities for additional location requirements.
