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.)

WARNING

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 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.
