Furnaces for upflow installation on combustible flooring shall not
be installed directly on carpeting, tile or other combustible mate-
rial other than wood flooring.

Check the rating plate and power supply to be sure that the elec-
trical 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.

Restricted Environments 

Commercial buildings 

Buildings with indoor pools 

Furnaces installed in laundry rooms 

Furnaces installed in hobby or craft rooms 

Furnaces installed near chemical storage areas 

Chemical exposure 

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.

Permanent wave solutions 

Chlorinated waxes and cleaners 

Chlorine based swimming pool chemicals 

Water softening chemicals 

De-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 

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.

CODES AND STANDARDS

Follow all national, local codes and standards in addition to this installa-
tion manual. The installation must comply with regulations of the serv-
ing gas supplier, local building, heating, plumbing, and other codes. In
absence of local codes, the installation must comply with the national
codes listed below and all authorities having jurisdiction.

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 fur-
nace.

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.
