INSTALLATION
REQUIREMENTS
These instructions are intended as a general guide only for use by

Protection Association; the National Fuel Gas Code, ANSI
Z223.1/NFPA No. 54 (latest edition) and the National Electrical
Code, ANSI/NFPA No. 70 (latest edition) in the United States, and
any state laws, local ordinances (including plumbing or

Location Requirements

Explosion Hazard
Keep flammable materials and vapors, such as
gasoline, away from furnace.
Place furnace so that burners are at least 18 inches
(46 cm) above the floor for a garage installation.
Failure to follow these instructions can result in death,
explosion, or fire.
Explosion Hazard
Do not install this furnace in a mobile home.
Doing so can result in death, explosion, fire, or
carbon monoxide poisoning.
IMPORTANT: Do not use the furnace as a heater in a building
under construction. The furnace can be severely damaged due to
the abnormal environment caused by construction. Chlorides
from sources such as paint, stain, or varnish; tile and counter
cements; adhesives; and foam insulation are abundant in a
structure under construction and can be highly corrosive. Low
return air temperature can cause condensation in the furnace and
other damage that can shorten the life of the furnace.
The condensate drain on this furnace is incorporated within
the furnace and must be primed before start-up. The
condensate system must not be exposed to temperatures
under 32°F.
The furnace is suitable for installation in buildings
constructed on site. The furnace should be centralized in
respect to the heat distribution system as much as
practicable.
