:
•These furnaces are designed for indoor installation only.
•These furnaces are NOT to be used as construction heaters.
•The return air duct of the furnace must be sealed air tight to prevent starvation of the combustion air, especially if the furnace is located in a closet or confined area.
For best performance locate the furnace so that it is centralized with respect to the duct system.
Place the unit so that proper venting can be achieved, with a minimum number of elbows, in accord with the instructions in this manual. The furnace should be located as close to the chimney (vertical venting) or to the outside vent wall (horizontal venting) as practical.
The furnace must be located on a level, dry surface in an area, which is free from and protected from excessive drafts.

If the area becomes wet or damp at times, the furnace should be raised above the floor using a concrete base, bricks, patio blocks, etc.
When installing this furnace, provisions must be made to insure the supply of adequate combustion and ventilation air in accordance with the air for combustion and ventilation section of the National Fuel Gas Code, NFPA 54/ANSI
