and masonry acid washing materials. If the furnace is
installed near an area which will be frequently con-
taminated by these substances, the furnace should
be sealed from this area so that little contaminated air
can reach the furnace. The furnace must still have an
adequate supply of combustion air, either from a
nearby uncontaminated room or from outdoors. For
details, see “AIR REQUIREMENTS” Section III.
• 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.
• When installed horizontally, the furnace must be in-
stalled with the access doors vertical so that the
burners fire horizontally into the heat exchanger. The
unit cannot be installed with the access doors on top
or bottom. (See Specification Sheet)
• Allow clearances from the enclosure as shown on
Specification Sheet for fire protection, proper opera-
tion, and service access. These clearances must be
permanently maintained. The combustion and venti-
lating air openings in the front and top panels of the
furnace must never be obstructed.
• This furnace shall not be connected to a chimney flue
serving a separate appliance designed to burn solid
fuel.
• When the furnace is used in connection with a cooling
unit, the furnace must be upstream of, or in parallel
with, the cooling unit. For details see Section VIlI.
• On Counterflow Installations, the air conditioning coil
must be downstream from the heat exchanger of the
furnace.
• Counterflow Installation over a noncombustible floor.
Before setting the furnace over the plenum opening,
insure the surface around the opening is smooth and
level. A tight seal should be made between the furnace
base and floor by using a silicone rubber caulking
compound or cement grout.
• Counterflow Installation over a combustible floor. If
installation over a combustible floor becomes neces-
sary, use an accessory subbase as shown on the
Specification Sheet. Follow the instructions with the
subbase for proper installation. Do not install the
furnace directly on carpeting, tile, or other combustible
material other than wood flooring. (Note: The subbase
will not be required if an air conditioning coil is installed
between the supply air opening on the furnace and the
floor.)
• 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.
ADDITIONAL LOCATION CONSIDERATIONS
• The furnace should be as centralized as is practical
with respect to the air distribution system.
• Do not install the furnace directly on carpeting, tile, or
combustible material other than wood flooring.
• When suspending the furnace from rafters or joists,
use 3/8" threaded rod and 2” x 2” x 3/8” angle as shown
on the Specification Sheet. The length of the rod will
depend on the application and clearance necessary.
I. Safety and Unit Location
WARNING
To prevent personal injury or death due to
improper installation, adjustment,
alteration, service, or, maintenance refer
to this manual or for additional assistance
or information consult a qualified installer,
service agency or the gas supplier.
WARNING
This product contains or produces a
chemical or chemicals which may cause
serious illness or death and which are
known to the State of California to cause
cancer, birth defects or other reproductive
harm.
WARNING
To prevent possible death, personal injury
or equipment damage due to fire, the
following points must be observed when
installing the unit.
WARNING
To prevent possible death, personal injury
or property damage due to electrical shock,
the furnace must be located to protect the
electrical components from water.
NOTE: This unit must not be used as a “construction
heater” during the finishing phases of construction on a
new structure. This type of use may result in premature
failure of the unit due to extremely low return air tempera-
tures and exposure to corrosive or very dirty atmospheres.
WARNING
To prevent possible death, personal injury
or property damage, do not install this unit
in a mobile home, trailer or recreational
vehicle.
ADDITIONAL SAFETY CONSIDERATIONS
• This furnace is approved for Category I Venting only.
• When the furnace is heating, the temperature of the
return air entering the furnace must be between 55°F
and 100°F.
• Do not install the furnace where the combustion air is
exposed to the following substances: permanent wave
solutions, chlorinated waxes or cleaners, chlorine
based swimming pool chemicals, water softening
chemicals, deicing salts or chemicals, carbon tetra-
chloride, halogen type refrigerants, cleaning solutions
(such as perchloroethylene), printing inks, paint re-
movers, varnishes, hydrochloric acid, cements and
glues, antistatic fabric softeners for clothes dryers,
