• Furnaces for installation on combustible flooring shall not be

installed directly on carpeting, tile or other combustible material
other than wood flooring.

• Check the rating plate and power supply to be sure that the electri-

cal characteristics match. All models use nominal 115 VAC, 1
Phase, 60-Hz power supply. DO NOT CONNECT THIS APPLI-
ANCE TO A 50-Hz POWER SUPPLY OR A VOLTAGE ABOVE
130 VOLTS.

• Furnace shall be installed so the electrical components are pro-

tected from water.

• Installing and servicing heating equipment can be hazardous due

to the electrical components and the gas fired components. Only
trained and qualified personnel should install, repair, or service
gas heating equipment. Untrained service personnel can perform
basic maintenance functions such as cleaning and replacing the
air filters. When working on heating equipment, observe precau-
tions in the manuals and on the labels attached to the unit and
other safety precautions that may apply.

COMBUSTION AIR QUALITY 

(LIST OF CONTAMINANTS)

The furnace requires 

OUTDOOR AIR

 for combustion when the furnace

is located in any of the following environments.

• Buildings with indoor pools

• Chemical exposure

• Commercial buildings

• Furnaces installed in hobby or craft rooms

• Furnaces installed in laundry rooms

• Furnaces installed near chemical storage areas

• Restricted Environments

The furnace requires 

OUTDOOR AIR

 for combustion when the furnace

is located in an area where the furnace is being exposed to the follow-
ing substances and / or chemicals.

• Antistatic fabric softeners for clothes dryers

• Carbon tetrachloride

• Cements and glues

• Chlorine based swimming pool chemicals

• Chlorinated waxes and cleaners

• Cleaning solvents (such as perchloroethylene)

• De-icing salts or chemicals

• Halogen type refrigerants

• Hydrochloric acid

• Masonry acid washing materials

• Permanent wave solutions

• Printing inks, paint removers, varnishes, etc.

• Water softening chemicals

When outdoor air is used for combustion, the combustion air intake duct
system termination must be located external to the building and in an
area where there will be no exposure to the substances listed above.

These instructions cover minimum requirements and conform to exist-
ing national standards and safety codes. In some instances these
instructions exceed certain local codes and ordinances, especially
those who have not kept up with changing residential and non-HUD
modular home construction practices. These instructions are required
as a minimum for a safe installation.

The furnace area must not be used as a broom closet or for any other
storage purposes, as a fire hazard may be created. Never store items
such as the following on, near or in contact with the furnace.

1. Spray or aerosol cans, rags, brooms, dust mops, vacuum

cleaners or other cleaning tools.

2. Soap powders, bleaches, waxes or other cleaning com-

pounds; plastic items or containers; gasoline, kerosene, ciga-
rette lighter fluid, dry cleaning fluids or other volatile fluid.

3. Paint thinners and other painting compounds.
4. Paper bags, boxes or other paper products

Never operate the furnace with the blower door removed. To do
so could result in serious personal injury and/or equipment
damage.
