Installation in a Garage
WARNING:
Do not place combustible material on or against
the furnace cabinet or within 6 inches of the
vent pipe. Do not place combustible materials,
including gasoline or any other flammable
vapors and liquids,in the vicinity of the furnace.
This Gas-fired furnace may be installed in a residential
garage with the provision that the burners and igniter
are located no less than 18 inches (457mm) above the
floor. The furnace must be located or protected to prevent
physical damage by vehicles.
Clearances to Combustible Materials
This furnace is Design Certified in the U.S. and Canada
by CSA International for the minimum clearances to
combustible material listed in
number and specific clearance information, refer to the
furnace rating plate, located inside of the furnace cabinet.
Access for positioning and servicing the unit must be
considered when locating unit. The need to provide
clearance for access to panels or doors may require
clearance distances over and above the requirements.
Allow 30 inches minimum clearance from the front
of the unit for servicing and positioning. However,
36 inches is strongly recommended.

Heating Load
This furnace should be sized to provide the design heating
load requirement. Heating load estimates can be made
using approved methods available from Air Conditioning
Contractors of America (Manual J); American Society of
Heating, Refrigerating, and Air Conditioning Engineers;
or other approved engineering methods. Excessive
oversizing of the furnace could cause the furnace
and/or vent to fail prematurely. In addition, the ductwork
should be appropriately sized to the capacity of the furnace
to ensure its proper airflow rating. For installations above
2,000 ft., the furnace should have a sea level input rating
large enough that it will meet the heating load after deration
for altitude.
