may also be used to prevent ESD damage.
LOCATION
I. GENERAL
CAUTION: Do not install furnace in a corrosive or
contaminated atmosphere. Make sure all combustion and
circulating air requirements are met, in addition to all
local codes and ordinances.
CAUTION: Do not use this furnace during construction
when adhesives, sealers, and/or new carpets are being
installed. If the furnace is required during construction,
use clean outside air for combustion and ventilation.
Compounds of chlorine and fluorine when burned with
combustion air form acids which cause corrosion of the
heat exchangers and metal vent system. Some of these
compounds are found in paneling and dry wall adhesives,
paints, thinners, masonry cleaning materials, and many
other solvents commonly used in the construction pro-
cess.
Excessive exposure to contaminated combustion air will
result in safety and performance related problems.
WARNING: DO NOT install the furnace on its back or
sides. Safety control operation will be adversely affected.
A failure to follow this warning can cause a fire, personal
injury, or death.
This furnace must be installed so the electrical components are
protected from water. This furnace shall not be installed directly on
carpeting, tile, or any combustible material other than wood
flooring.
Locate furnace as close to the chimney/vent and as near the center
of the air distribution system as possible. The furnace should be
installed as level as possible.
Provide ample space for servicing and cleaning. Always comply
with the minimum fire protection clearances shown on the unit
rating plate.
II. LOCATION RELATIVE TO COOLING EQUIPMENT
The cooling coil must be installed parallel with or on the
downstream side of the unit to avoid condensation in the heat
exchangers. When installed parallel with a furnace, dampers or
other means used to control the flow of air must prevent chilled air
from entering the unit. If the dampers are manually operated, they
must be equipped with means to prevent operation of either unit
unless the damper is in the full-heat or full-cool position.
III. HAZARDOUS LOCATIONS
Air For Combustion and Ventilation
Provisions for adequate combustion and ventilation air must be
provided in accordance with Section 5.3 of the NFGC, Air for
Combustion and Ventilation, or applicable provisions of the local
building codes.
Canadian installations must be installed in accordance with NSC-
NGPIC and all authorities having jurisdiction.
WARNING: When furnace is installed in a residential
garage, it must be installed so that burners and ignition
sources are located a minimum of 18 in. above floor. The
furnace must be located or protected to avoid physical
damage by vehicles. When furnace is installed in a public
garage, airplane hangar, or other building having a
hazardous atmosphere, unit must be installed in accor-
dance with requirements of National Fire Protection
Association, Inc.
CAUTION: Air for combustion must not be contami-
nated by halogen compounds, which include fluoride,
chloride, bromide, and iodide. These elements are found
in aerosol sprays, detergents, bleaches, cleaning solvents,
salts, air fresheners, and other household products.
All fuel-burning equipment must be supplied with air for combus-
tion of the fuel. Sufficient air MUST be provided to ensure there
will not be a negative pressure in the equipment room or space. In
addition, a positive seal MUST be made between the furnace
cabinet and the return-air duct to prevent pulling air from the
burner area and blocked vent safeguard opening.
CAUTION: The operation of exhaust fans, kitchen ven-
tilation fans, clothes dryers, or fireplaces could create a
NEGATIVE PRESSURE CONDITION at the furnace.
Make-up air MUST BE PROVIDED for the ventilation
devices, in addition to that required by the furnace.
The requirements for combustion and ventilation air depend upon
whether the furnace is located in an unconfined or confined space.
IV. UNCONFINED SPACE
An unconfined space has volume of at least 50 cu ft for each 1000
Btuh of total input for all appliances (such as furnaces, clothes
dryers, water heaters, etc.) in the space.
For Example:
If the unconfined space is of unusually tight construction, air for
combustion and ventilation MUST come from either the outdoors
or spaces freely communicating with the outdoors. Combustion
and ventilation openings must be sized the same as for a confined
space as defined below. Return air must not be taken from the
room unless an equal or greater amount of air is supplied to the
room.
