WARNING
!
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. (See Fig. 6.)
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.

PERSONAL INJURY AND/OR PROPERTY
DAMAGE HAZARD
Improper use or installation of this furnace may result in
premature furnace component failure. 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
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
A02054
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.
