A gas- -fired furnace for installation in a residential garage must be
installed as specified in the Hazardous Locations section of these
instructions and Fig. 5.
The furnace may be used for construction heat provided that the
furnace installation and operation complies with the first
CAUTION in the LOCATION section of these instructions.
This gas furnace may be used for construction heat provided that:
S The furnace is permanently installed with all electrical wiring,
piping, air filters, 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.
S The furnace is controlled by a thermostat. It may not be "hot
wired" to provide heat continuously to the structure without
thermostatic control.
S 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.
S 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.
S The air temperature rise is within the rated rise range on the
furnace rating plate, and the firing rate has been set to the
nameplate value.
S The filters used to clean the circulating air during the
construction process must be either changed or thoroughly
cleaned prior to occupancy.
S 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.
S After construction is complete, verify furnace operating
conditions including ignition, input rate, temperature rise and
venting, according to the manufacturer's instructions.
