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 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.
