GENERAL INFORMATION
DESCRIPTION
This Category I furnace is designed for installation in a residen-
tial or commercial application. A Category 1 furnace has a fan
assisted combustion system equipped with an integral me-
chanical means to draw products of combustion through the
combustion chamber and heat exchanger. It may be installed
in a basement, garage, equipment room, alcove, attic or any
other indoor location where all required clearances to combus-
tibles and other restrictions are met. It is designed for natural
gas-fired operation, but may be converted to propane (LP).
High altitude and propane (LP) changes or conversions re-
quired in order for the appliance to satisfactorily meet the
application must be made by an authorized distributor: in
Canada, a certified conversion station or other qualified
agency, using factory specified and/or approved parts.
Upflow/horizontal (P2MP) furnaces and downflow (P2DP) fur-
naces may be used only as Category 1 units.
The furnace must be installed so that all electrical components
are protected from water.
INSPECTION
As soon as a unit is received, it should be inspected for possible
damage during transit. If the damage is evident, the extent of
the damage should be noted on the carrier’s freight bill.
A separate request for inspection by the carrier’s agent should be
made in writing. Also, before installation, the unit should be
checked for screws or bolts which may have loosened in transit.
NOTES, CAUTIONS & WARNINGS
The installer should pay particular attention to the words:
NOTE, CAUTION and WARNING. NOTES are intended to
clarify or make the installation easier. CAUTIONS are given to
prevent equipment damage. WARNINGS are given to alert the
installer that personal injury and/or equipment or property
damage may occur if installation procedures are not handled
properly.
WARNING: 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, vac-
uum cleaners or other cleaning tools.
2. Soap powders, bleaches, waxes or other cleaning com-
pounds; plastic items or containers; gasoline, kerosene,
cigarette lighter fluid, dry-cleaning fluids or other volatile fluid.
3. Paint thinners and other painting compounds.
4. Paper bags, boxes or other paper products.
WARNING: Never operate the furnace with the blower door
removed. To do so could result in serious personal injury
and/or equipment damage.
WARNING: Each furnace in this series is a Category I furnace,
suitable for common venting with other gas-fired appli-
ances as allowed by the National Fuel Gas Code, NFPA
54/ANSI Z223.1-latest edition.
WARNING: This appliance is not to be used for temporary
heating of buildings or structures under construction.
WARNING: Do not install this furnace in a corrosive or con-
taminated atmosphere.
WARNING: Do not install this furnace in a mobile home or
recreational vehicle.
WARNING: Furnaces shall not be installed directly on carpeting,
tile or other combustible material other than wood flooring.
LIMITATIONS AND LOCATION
This furnace should be installed in accordance with all na-
tional/local building/safety codes and requirements, or in the
absence of local codes, with the National Fuel Gas Code, ANSI
Z223.1 - (latest edition) or, in Canada, CAN/CGA B149.1 or .2
- (latest edition), and other applicable codes.
Use only the type of gas approved for this furnace; refer to the
furnace rating plate.
WARNING: Only use natural gas in furnaces designed for
natural gas. Only use propane (LP) gas for furnaces that
have been properly converted to use propane (LP) gas.
Do not use this furnace with butane. Using wrong gas
could create a hazard, resulting in damage, injury or death.
For installations above 2,000 feet, reduce input 4% for each
1,000 feet above sea level. Canadian installations must be
derated 10% for elevations from 2,000 ft. to 4,500 ft. Accessory
high altitude kits are available to properly derate furnace.
In the U.S. only, furnace shall not be connected to a chimney
flue serving a separate appliance designed to burn solid fuel.
Check the rating plate and power supply to be sure that
electrical characteristics match. All models use nominal 120
vac, 1 Ø, 60 Hz. power supply.
A furnace installed in a residential garage must be located so
that all burners and burner ignition devices are located no less
than 18" above the garage floor, and located or protected to
prevent damage by vehicles.
