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 igniter is 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. for the minimum
clearances to combustible materials.
NOTE:
The furnace
is listed for installation on combustible or non-combustible
flooring. However, wood is the only combustible flooring
allowed for installation. To obtain model 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 24 inches minimum
clearance from the front of the unit. However 36 inches
is strongly recommended.
See
for minimum
clearance requirements.
Operation of Furnace During Construction
CAUTION:
Operating gas furnaces in construction
environments can cause a variety of problems
within the furnace and may significantly
reduce the life or the performance of the
furnace. Therefore operating the furnace during
construction is not permitted and will void the
warranty.

WARNING:
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below
for each appliance connected to the venting
system being placed into operation could
result in carbon monoxide poisoning or death.
The following steps shall be followed with
each individual appliance connected to the
venting system being placed in operation,
while all other appliances connected to the
venting system are not in operation:
1. Seal any unused openings in the venting
system.
2. Inspect the venting system for proper size
and horizontal pitch, as required in the National
Fuel Gas Code, ANSI Z223.1/NFPA 54 and
these instructions. Determine that there is no
blockage or restriction, leakage, corrosion and
other deficiencies which could cause an unsafe
condition.
3. As far as practical, close all building doors
and windows and all doors between the space
in which the appliance(s) connected to the
venting system are located and other spaces
of the building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance
not connected to the venting system. Turn on
any exhaust fans, such as range hoods and
bathroom exhausts, so they are operating at
maximum speed. Do not operate a summer
exhaust fan.
6. Follow the lighting instructions. Place the
appliance being inspected into operation.
Adjust the thermostat so appliance is operating
continuously.
7. Test for spillage from draft hood equipped
appliances at the draft hood relief opening
after 5 minutes of main burner operation. Use
the flame of a match or candle.
8. If improper venting is observed during any of
the above tests, the venting system must be
corrected in accordance with the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 and/or CSA
B149.1, Natural Gas and Propane Installation
Codes.
9. After it has been determined that each
appliance connected to the venting system
properly vents when tested as outlined above,
return doors, windows, exhaust fans, fireplace
dampers and any other gas-fired burning
appliance to their previous conditions of use.
