INSTALLATION

T

hese instructions must be hung on or near the furnace in a

conspicuous place.

These furnace units are single package air conditioners with
gas heat designed for outdoor installation on a rooftop or a
slab.

The units are completely assembled. All piping, refrigerant
charge, and electrical wiring are factory installed and tested.
The units require only electric power, gas piping, condensate
drain, and duct connections, plus instruction of the vent cover
at the point of installation.

If components are to be added to a unit to meet local codes,
they are to be installed at the dealer’s and/or customer’s
expense.

The size of unit for the proposed installation should be based
on heat loss/heat gain calculation made according to the
methods of Air Conditioning Contractors of America (ACCA).
See Table 1 for application limitations.

Inspection

As soon as the unit is received, it should be inspected for
possible damage during transit. If damage is evident, the
extent of the damage should be noted on the carrier’s freight
bill.  A separate request for inspection by the carrier’s agent
should be made in writing.

Location

Use the following guidelines to select a suitable location for
these units.

1.

Unit is designed for outdoor installation only. Unit must
be installed so all electrical components are protected
from water.

2.

Condenser coils must have an unlimited supply of air.

3.

For ground level installation, use a level prefabricated
pad or use a level concrete slab.  Do not tie the slab to
the building foundation.

4.

Maintain level within a tolerance of 1/4" maximum across
the entire length or width of the unit.

5.

Do not locate the unit where the combustion air supply
will be exposed to any of the following substances:

Permanent wave solutions

Chlorinated waxes and cleaners

Chlorine-based swimming pool chemicals

Water softening chemicals

Deicing salts or chemicals

Carbon tetrachloride

Halogen-type refrigerants

Cleaning solvents (such as perchloroethylene)

Printing inks, paint removers, varnishes, etc.

Cements and glues

Antistatic fabric softeners for clothes dryers

Masonry acid washing materials

Chlorinated laundry products

Hydrochloric acid

These installation instructions are intended as a general
guide only, for use by an experienced, qualified
contractor.

In the State of Massachusetts:

This product must be installed by a licensed Plumber or
Gas Fitter.  When flexible connectors are used, the
maximum length shall not exceed 36".  When lever-type
gas shutoffs are used, they shall be T-handle type.

  WARNING

These units are certified by E.T.L. Testing Laboratories, Inc.:

For use as a forced air furnace with cooling unit.

For outdoor installation only.

For installation on combustible material.

For use with natural gas or propane gas.
(Conversion kit required for propane gas application.)

These units are not suitable for use with conventional
venting systems.
