CAUTION

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.

General

These furnaces are shipped with materials to assist in proper

furnace installation. These materials are shipped in the main

blower compartment.
See

Table 2

for loose parts bag contents.

This furnace must:

•

be installed so the electrical components are protected

from water.

•

not be installed directly on any combustible material other

than wood flooring (refer to SAFETY

CONSIDERATIONS).

•

be located close to the chimney or vent and attached to an

air distribution system. Refer to Air Ducts section.

•

be provided ample space for servicing and cleaning.

Always comply with minimum fire protection clearances

shown in

Table 1

or on the furnace clearance to

combustible construction label.

WARNING

CARBON MONOXIDE POISONING / COMPONENT

DAMAGE HAZARD

Failure to follow this warning could result in personal in-

jury or death and unit component damage.
Corrosive or contaminated air may cause failure of parts

containing flue gas, which could leak into the living

space. Air for combustion must not be contaminated by

halogen compounds, which include fluoride, chloride,

bromide, and iodide. These elements can corrode heat

exchangers and shorten furnace life. Air contaminants

are found in aerosol sprays, detergents, bleaches, clean-

ing solvents, salts, air fresheners, and other household

products. Do not install furnace in a corrosive or contam-

inated atmosphere. Make sure all combustion and circu-

lating air requirements are met, in addition to all local

codes and ordinances.

The following types of furnace installations may require

OUTDOOR AIR for combustion due to chemical exposures:

•

Commercial buildings

•

Buildings with indoor pools

•

Laundry rooms

•

Hobby or craft rooms, and

•

Chemical storage areas

If air is exposed to the following substances, it should not be

used for combustion air, and outdoor air may be required for

combustion:

•

Permanent wave solutions

•

Chlorinated waxes and cleaners

•

Chlorine based swimming pool chemicals

•

Water softening chemicals

•

−

icing salts or chemicals

•

Carbon tetrachloride

•

Halogen type refrigerants

•

Cleaning solvents (such as perchloroethylene)

•

Printing inks, paint removers, varnishes, etc.

•

Hydrochloric acid

•

Cements and glues

•

Antistatic fabric softeners for clothes dryers

•

Masonry acid washing materials

All fuel

−

burning equipment must be supplied with air for fuel

combustion. Sufficient air must be provided to avoid negative

pressure in the equipment room or space. A positive seal must

be made between the furnace cabinet and the return

−

air duct

to prevent pulling air from the burner area.
