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 Contractors 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. In Canada, this furnace
must be installed in accordance with the current CAN/CGA-B149.1
& 2 Gas Installation Codes, local plumbing or waste water codes and
other applicable codes. 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 Condi-
tioning System.
All venting shall be in accordance with PART 7, Venting of Equip-
ment, of the National Fuel Gas Code, ANSI Z223.1, or applicable
local building and/or air conditioning codes. These publications are
available from:

Your unit model type determines which installation procedures must
be used. For *MVC8 models, you must follow instructions for Hori-

WARNING
Follow the instructions listed below when selecting a furnace loca-
tion. Refer also to the guidelines provided in
Section V, 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.
•
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
section
.
•
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.
•
If the furnace is installed in a residential garage, position
the furnace so that the burners and ignition source are
located not less than 18 inches (457 mm) above the floor.
Protect the furnace from physical damage by vehicles.
•
If the furnace is installed horizontally, the furnace access
doors must be vertical so that the burners fire horizontally
into the heat exchanger. Do not install the unit with the
access doors on the “up/top” or “down/bottom” side of the
furnace.
•
Do not connect this furnace to a chimney flue that serves
a separate appliance designed to burn solid fuel.
