WARNING
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 absence, 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
25 West 43rd Street, 4th Floor
New York, NY 10036
National Fire Protection Association

Quincy, MA 02169
CSA International

Cleveland, OH 44131
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 accordance with “ASHRAE Guide” or “Manual
J-Load Calculations” published by the Air Conditioning Con-
tractors of America.
In the USA, this furnace MUST be installed in accordance with
the latest edition of the ANSI Z223.1 booklet entitled “National
Fuel Gas Code” (NFPA 54), and the requirements or codes of
the local utility or other authority having jurisdiction. Additional
helpful publications available from the NFPA are, NFPA 90A
- Installation of Air Conditioning and Ventilating System and
NFPA 90B - Warm Air Heating and Air Conditioning System.
All venting shall be in accordance with the National Fuel Gas
Code, ANSI Z223.1, or applicable local building and/or air
conditioning codes.
NOTE:
Furnaces with NOx screens meet the California NOx
emission standards and California seasonal efficiency stan
-
dards. ANNUAL inspections of the furnace and its vent system
is strongly recommended.
Location Requirements and Considerations
DM80SE models are approved for up flow and horizontal
(left or right side down) installation. DC80SE models are ap-
proved for down flow and horizontal (left or right side down)
installation.

WARNING
Follow the instructions listed below when selecting a furnace
location. Refer also to the guidelines provided in
Combustion
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.
• If the furnace is installed in an application where
the typical operating sound level of a furnace is
deemed objectionable, an optional sound reduction
kit is available. Consult your local distributor for more
details.
• Provisions must be made for venting combustion
products outdoors through a proper venting system.
The length of flue pipe could be a limiting factor in
locating the furnace.
•
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.
•
The furnace must be level. If the furnace is to be set
on a floor that may become wet or damp at times,
the furnace should be supported above the floor on
a concrete base sized approximately 1-1/2” larger
than the base of the furnace.
•
Ensure upflow or horizontal furnaces are not installed
directly on carpeting, or any other combustible
material. The only combustible material allowed is
wood.
•
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
halogen type refrigerants
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
• If the furnace is used in connection with a cooling
unit, install the furnace upstream or in parallel with the
cooling unit coil. Premature heat exchanger failure
will result if the cooling unit coil is placed ahead of
the furnace.
