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.

REPAIR OPERATION OR MAINTENANCE
• 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 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.

OF THIS PRODUCT
• 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
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
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 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:
permanent wave solutions
,
chlorinated waxes or cleaners
MUST BE
chlorine-based swimming pool chemicals
water softening chemicals
deicing salts or chemicals
carbon tetrachloride
TO
halogen type refrigerants
SHOCK
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
• Seal off a non-direct vent furnace if it is installed near an
area frequently contaminated by any of the above
substances. This protects the non-direct vent furnace
from airborne contaminants. To ensure that the
enclosed non-direct vent furnace has an adequate supply
of combustion air, vent from a nearby uncontaminated
room or from outdoors. Refer to the Combustion and
Ventilation Air Requirements for details.
