Leave at least three-feet in front of the wall furnace for servicing and proper operation. The wall furnace must be installed in such
a way that the external casing can be completely removed for servicing.
If there is a shelf above the furnace, it must be be noncombustible. A minimum clearance of 12-inches (300 mm) is
recommended between the furnace and the noncombustible shelf above it.
Gas equipment in residential garages must be installed so that all burners and burner ignition devices are located not less than
18-inches (460 mm) above the floor. Such equipment must be located, or protected, so it is not subject to physical damage by a
moving vehicle.
The vent terminal of this direct-vent furnace must be located at least 9-inches (230 mm) from any opening through which flue
gases could enter a building. The bottom of the vent terminal and the air intake must be located at least 12-inches (300mm)
above grade.
DO NOT cover the furnace.
Make sure that the correct gas supply is available.
The furnace requires a 120V, 60 Hz electrical supply.
The furnace must be electrically grounded in accordance with local codes or in the absence of local codes, with the National

WARNING: The nearest point of the vent cap should be a minimum horizontal distant of six (6) feet (1,830 mm)
from any pressure regulator. In case of regulator malfunction, the six (6) feet (1,830 mm) distance will reduce
the chance of gas entering the vent cap.
