checked for screws or bolts which may have loosened in transit.
There are no shipping or spacer brackets which need to be
removed before startup.
FURNACE LOCATION AND CLEARANCES
The furnace shall be located using the following guidelines
1.
Where a minimum amount of air intake/vent piping
(smallest roof jack) will be required.
2.
As centralized with the air distribution as possible.
3.
Where adequate combustion air will be available
(particularly when appliance is not using outdoor air for
combustion air).
4.
Where it will not interfere with proper air circulation in the
confined space.
5.
Where the outdoor combustion air/ vent terminal will not be
blocked or restricted. Refer to combustion air/ vent
instructions located in Section VI. These minimum
clearances must be maintained throughout the installation.
6.
Where the appliance will be installed in a level position
with no more than ¼” (0.6 cm) slope side to side and front
to back to provide proper condensate drainage.
INSTALLATION IN FREEZING TEMPERATURES
1.
Furnace shall be installed in an area where ventilation
facilities provide for safe limits of ambient temperature
under normal operating conditions. Ambient temperatures
must not fall below 32° F (0° C) unless the condensate
system is protected from freezing.
2.
Do not allow the return air temperature to be below 55°F
(13°C) for extended periods. To do so may cause
condensate to occur in the main heat exchanger, leading to
premature heat exchanger failure.
CLEARANCES FOR ACCESS
Ample clearances should be provided to permit easy access to
the appliance. The following minimum clearances are
recommended.
1.
Twenty-four (24) inches (61 cm) between the front of the
furnace and an adjacent wall or other appliance, when
access is required for servicing or cleaning.
2.
Eighteen (18) inches (46 cm) at the side where access is
required for passage to the front when servicing or for
inspection or replacement of the flue/vent connections.

INSTALLATION IN A RESIDENTIAL GARAGE
A gas-fired furnace for installation in a residential garage must
be installed as specified in these instructions. For installation in
a residential garage, the furnace must be installed so the gas
burner(s) and the ignition source are located not less than 18
inches (46 cm) above the floor. The appliance must be located
or protected to avoid physical damage by vehicles.

LOW AMBIENT TEMPERATURE HAZARD
Improper installation in an ambient temperature that is
consistently below 55°F (13°C) could result in a hazard
resulting in premature heat exchanger failure, a fire,
property damage, personal injury or loss of life.
DO NOT store any chemicals or volatile fluids around the
appliance. This is a very dangerous practice that must be
avoided.
Storing chemicals around the appliance can lead to heat
exchanger corrosion which will cause premature heat
exchanger failure, which may result in personal injury,
substantial property damage or death.
Storing volatile fluids around the appliance can lead to an
explosion which can cause substantial property damage
that may result in personal injury, or death.
