FIRE, INJURY OR DEATH HAZARD
Failure to follow this warning could result in personal
injury, death and/or property damage.
When the furnace is installed in a residential garage,
the burners and ignition sources must be located at
least 18 in. (457 mm) above the floor. The furnace
must be located or protected
to avoid damage by
vehicles.
When the furnace is installed
in a public
garage, airplane
hangar, or other building
having a
hazardous atmosphere, the furnace must be installed
in accordance
with the NFPA 54/ANSI Z223.1-2009.
(See Figure 5)
PERSONAL INJURY AND/OR PROPERTY
DAMAGE HAZARD
Failure to follow this caution may result in furnace
component
damage.
This gas furnace may be used for heating buildings
under construction provided that:
-The
furnace
is permanently
installed
with
all
electrical wiring, piping, venting and ducting installed
according to these installation
instructions. A return
air duct is provided, sealed to the furnace casing, and
terminated outside the space containing the furnace.
This
prevents
a negative
pressure
condition
as
created by the circulating air blower, causing a flame
rollout and/or drawing combustion
products into the
structure.
-The furnace is controlled by a thermostat. It may not
be hot wired to provide
heat continuously
to the
structure without thermostatic
control.
-Clean
outside air is provided for combustion. This is
to minimize
the
corrosive
effects
of adhesives,
sealers
and
other
construction
materials.
It also
prevents
the
entrainment
of
drywall
dust
into
combustion air, which can cause fouling and plugging
of furnace components.
-The temperature
of the return air to the furnace is
maintained
between 55°F (13°C) and 80°F (27°C),
with no evening setback or shutdown. The use of the
furnace while the structure
is under construction
is
deemed
to
be
intermittent
operation
per
our
installation instructions.
-The
air temperature
rise is within the rated
rise
range on the furnace rating plate, and the gas input
rate has been set to the nameplate value.
-The filters used to clean the circulating air during the
construction
process
must
be either
changed
or
thoroughly cleaned prior to occupancy.
-The
furnace,
ductwork
and filters are cleaned as
necessary to remove drywall dust and construction
debris
from
all HVAC
system
components
after
construction is completed.
-Verify proper furnace operating conditions including
ignition,
gas input rate, air temperature
rise, and
venting according to these installation instructions.

FIRE HAZARD
Failure to follow this warning could result in personal
injury, death and/or property damage.
Do not install the furnace on its back or hang furnace
with control
compartment
facing downward.
Safety
control operation
will be adversely
affected.
Never
connect return-air
ducts to the back of the furnace.

LOCATION RELATIVE TO COOLING EQUIPMENT
The cooling
coil must be installed parallel with, or on the
downstream side of the unit to avoid condensation
in the heat
exchangers.
When
installed
parallel
with
the
furnace,
dampers or other flow control must prevent chilled air from
entering the furnace. If the dampers are manually operated,
they must be equipped with means to prevent operation of
either unit unless the damper is in the full-heat
or full-cool
position.
AIR FOR COMBUSTION
AND
VENTILATION
Provisions for adequate combustion,
ventilation,
and dilution
air must be provided in accordance with:
Section 9.3 of the NFPA 54/ANSI
Z223.1-2009,
Air
for Combustion and Ventilation, and applicable pro-
visions of the local building codes.
