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, Combus-

tion 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.

Provide provisions for venting combustion products
outdoors through a proper venting system.  Special
consideration should be given to vent/flue pipe routing
and combustion air intake pipe when applicable.  Refer
to 

Section IX, Vent/Flue Pipe and Combustion Air Pipe -

Termination Locations 

for appropriate termination

locations and to determine if the piping system from
furnace to termination can be accomplished within the
guidelines given.  

NOTE:

  The length of flue and/or

combustion air piping can be a limiting factor in the
location of the furnace.

Locate the furnace so condensate flows downwards to
the drain.  Do not locate the furnace or its condensate
drainage system in any area subject to below freezing
temperatures without proper freeze protection. Refer to

Section X, Condensate Drain Lines and Trap

 for further

details.

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.

Set the furnace on a level floor to enable proper
condensate drainage.  If the floor becomes wet or damp
at times, place the furnace above the floor on a concrete
base sized approximately 1-1/2" larger than the base of
the furnace.  Refer to the 

Section VII, Horizontal

Applications and Considerations

 for leveling of horizontal

furnaces.

Ensure upflow or horizontal furnaces are not installed
directly on carpeting, or any other combustible material.
The only combustible material allowed is wood.

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.  (NOTE: A subbase will not be
required if an air conditioning coil is located beneath the
furnace between the supply air opening and the
combustible floor.

Exposure to contaminated combustion air will result in
safety and performance-related problems.  Do not install
the 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

NOTE:

 Do not connect the temporary duct directly to the

furnace. The duct must be sized according to the
instructions under 

Section V, Combustion and Ventilation

Air Requirements, Section 5.3.3.

The furnace heat exchanger, components, duct system,
air filters and evaporator coils are thoroughly cleaned
following final construction clean up.

All furnace operating conditions (including ignition, input
rate, temperature rise and venting) are verified according
to these installation instructions.

NOTE: 

The Commonwealth of Massachusetts requires that the

following additional requirements must also be met:

Gas furnaces must be installed by a licensed plumber or
gas fitter.

A T-handle gas cock must be used.

If the unit is to be installed in an attic, the passageway to
and the service area around the unit must have flooring.

To ensure proper installation and operation, thoroughly read this
manual for specifics pertaining to the installation and application
of this product.

WARNING

P

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

T

O PREVENT PROPERTY DAMAGE, PERSONAL INJURY OR DEATH DUE TO FIRE,

DO NOT INSTALL THIS FURNACE IN A MOBILE HOME, TRAILER, OR RECREATIONAL

VEHICLE.

To ensure proper furnace operation, install, operate and maintain
the furnace in accordance with these installation and operation
instructions, all local building codes and ordinances.  In their ab-
sence, follow the latest edition of the National Fuel Gas Code
(NFPA 54/ANSI Z223.1), and/or CAN/CSA B149 Installation Codes,
local plumbing or waste water codes, and other applicable codes.
A copy of the National Fuel Gas Code (NFPA 54/ANSI Z223.1) can
be obtained from any of the following:

American National Standards Institute
1430 Broadway
New York,  NY  10018

National Fire Protection Association
1 Batterymarch Park
Quincy, MA  02269

CSA International

A copy of the CAN/CSA B149 Installation Codes can also be ob-
tained from:

CSA International
178 Rexdale Boulevard
Etobicoke, Ontario, Canada M9W 1R3

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 accor-
dance with “ASHRAE Guide” or “Manual J-Load Calculations” pub-
lished by the Air Conditioning Contractors of America.
