The air handling capacity of this furnace is designed for cooling
airflow. Refer to Table 12 for expected airflows at various external
duct static pressures.

LOCATION

GENERAL

WARNING:

This furnace is not water tight and is not

designed for outdoor installation. This furnace shall be
installed in such a manner as to protect electrical com-
ponents from water. Outdoor installation would lead to a
hazardous electrical condition and to premature furnace
failure.

WARNING:

Do not use this furnace as a construction

heater. Use of this furnace as a construction heater
exposes furnace to abnormal conditions, contaminated
combustion air, and lack of air filters. Failure to follow
this warning can lead to premature furnace failure and/or
vent failure which could result in a fire hazard and/or
bodily harm.

CAUTION:

For attic installation, it is important to keep

insulation 12 in. or more away from any furnace open-
ings. Some types of insulating materials may be combus-
tibles and may cause a fire hazard and property damage.

This furnace is approved for reduced clearances to combustible
construction, therefore, it may be installed in a closet or similar
enclosure. Since this unit may be installed in an upflow, counter-
flow, or horizontal position, it may be located in a basement or on
the same level as area to be heated. In any case, unit should always
be installed level.
In a basement, or when installed on floor (as in a crawlspace), it is
recommended that unit be installed on a concrete pad that is 1 in.
to 2 in. thick.
When installed in counterflow position, furnace must not be
installed on combustible flooring, unless approved subbase is used.
Also, since flue pipe is in a counterflow position, Downflow
Conversion/Vent Guard Kit MUST be used. (Also, read page 9.)
When installed in a horizontal position, furnace may be suspended
by using an angle iron frame, as long as total weight of both
furnace and frame are allowed for in support calculations. (Other
methods of suspending are acceptable.) When installed in the
Horizontal Position, this furnace must not be installed on combus-
tible flooring, unless the approved Horizontal Subbase is used.
The required minimum clearances for furnace are specified in
Table 1.

The furnace should be located as close as possible to chimney or
vent in order to keep vent connections short and direct. The
furnace should also be located as near as possible to center of air
distribution system.

II.

LOCATION RELATIVE TO COOLING EQUIPMENT

When installing furnace with cooling equipment for year-round
operation, the following recommendations must be followed for
series or parallel airflow:

1. In series airflow applications, coil is mounted after furnace

in an enclosure in supply-air stream. The furnace blower is
used for both heating and cooling airflow.

WARNING:

The coil MUST be installed on air dis-

charge side of furnace. Under no circumstances should
airflow be such that cooled, conditioned air can pass over
furnace heat exchanger. This will cause condensation in
heat exchanger and possible failure of heat exchanger
which could lead to a fire hazard and/or a hazardous
condition which may lead to bodily harm. Heat exchanger
failure due to improper installation may not be covered by
warranty.

2. In parallel airflow applications, dampers must be provided

to direct air over furnace heat exchanger when heat is
desired and over cooling coil when cooling is desired.

IMPORTANT:

The dampers should be adequate to prevent

cooled air from entering furnace. If manually operated, dampers
must be equipped with a means to prevent operation of either
cooling unit or furnace unless damper is in full cool or heat
position.

INSTALLATION

AIR FOR COMBUSTION AND VENTILATION

WARNING:

Installation of this furnace in an area where

it will receive contaminated combustion air must be
avoided. Such contamination would include the follow-
ing: ammonia, chlorine, hydrogen sulfide, halogenated
hydrocarbons, carbon tetrachloride, cleaning solvents,
hydrochloric acid, water softening chemicals, and similar
chemicals. Failure to follow this warning will lead to
premature rusting of heat exchanger and possible prema-
ture furnace failure and/or vent failure which could result
in fire hazard and/or bodily harm.
