furnace where the combustion air is exposed to the

following substances:

chlorinated waxes or cleaners

chlorine-based swimming pool chemicals

water softening chemicals

deicing salts or chemicals

carbon tetrachloride

halogen type refrigerants

cleaning solutions (such as perchloroethylene)

printing inks

paint removers

varnishes

hydrochloric acid

cements and glues

antistatic fabric softeners for clothes dryers

and masonry acid washing materials

• If the furnace is used in connection with a cooling unit,

install the furnace upstream or in parallel with the cooling

unit coil. Premature heat exchanger failure will result if

the cooling unit coil is placed ahead of the furnace.

• If the furnace is installed in a residential garage, position

the furnace so that the burners and ignition source are

located not less than 18 inches (457 mm) above the floor.

Protect the furnace from physical damage by vehicles.

• If the furnace is installed horizontally, the furnace access

doors must be vertical so that the burners fire horizontally

into the heat exchanger. Do not install the unit with the

access doors on the “up/top” or “down/bottom” side of

the furnace.

• Do not connect this furnace to a chimney flue that serves

a separate appliance designed to burn solid fuel.

• On Counterflow Installations, the air conditioning coil must

be downstream from the heat exchanger of the furnace.

• Counterflow Installation over a noncombustible floor.

Before setting the furnace over the plenum opening,

ensure the surface around the opening is smooth and

level. A tight seal should be made between the furnace

base and floor by using a silicone rubber caulking

compound or cement grout.

• Counterflow Installation over a combustible floor. If

installation over a combustible floor becomes necessary,

use an accessory subbase (see Product Data Bulletin

for details). A special accessory subbase must be used

for upright counterflow unit installations over any

combustible material including wood. Refer to subbase

instructions for installation details. Follow the instructions

with the subbase for proper installation. Do not install the

furnace directly on carpeting, tile, or other combustible

material other than wood flooring. (Note: The subbase

will not be required if an air conditioning coil is installed

between the supply air opening on the furnace and the

floor.)

CLEARANCES AND ACCESSIBILITY

Installations must adhere to the clearances to combustible materi-

als which this furnace has been design certified to.

The minimum clearance information for this furnace is provided on

the unit clearance label. These clearances must be permanently

maintained. Clearances must also accommodate an installation’s

The rated heating capacity of the furnace should be greater than or

equal to the total heat loss of the area to be heated. The total heat

loss should be calculated by an approved method or in accordance

with “ASHRAE Guide” or “Manual J-Load Calculations” published by

the Air Conditioning Contractors of America.

WARNING

OSSIBLE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH DUE TO FIRE,

EXPLOSION, SMOKE, SOOT, CONDENSTAION, ELECTRICAL SHOCK OR CARBON

MONOXIDE MAY RESULT FROM IMPROPER INSTALLATION, REPAIR, OPERATION,

OR MAINTENANCE OF THIS PRODUCT.

WARNING

O PREVENT POSSIBLE EQUIPMENT DAMAGE, PROPERTY DAMAGE, PERSONAL

INJURY OR DEATH, THE FOLLOWING BULLET POINTS MUST BE OBSERVED

WHEN INSTALLING THE UNIT.

Follow the instructions listed below when selecting a furnace loca-

tion. Refer also to the guidelines provided in Section V, Combustion

and Ventilation Air Requirements.

• Centrally locate the furnace with respect to the proposed

or existing air distribution system.

• Ensure the temperature of the return air entering the furnace

is between 55°F and 100°F when the furnace is heating.

• Provisions must be made for venting combustion products

outdoors through a proper venting system. The length of

flue pipe could be a limiting factor in locating the furnace.

• Ensure adequate combustion air is available for the furnace.

Improper or insufficient combustion air can expose building

occupants to gas combustion products that could include

carbon monoxide. Refer to Section V, Combustion and

Ventilation Air Requirements.

• The furnace must be level. If the furnace is to be set on a

floor that may become wet or damp at times, the furnace

should be supported above the floor on a concrete base

sized approximately 1-1/2" larger than the base of the

furnace.

• Ensure upflow or horizontal furnaces are not installed

directly on carpeting, or any other combustible material.

The only combustible material allowed is wood.

• Exposure to contaminated combustion air will result in safety

and performance-related problems. Do not install the
