INSTALLATION

For detailed installation instructions, see the
Owner’s Operation and Installation Manual that
is packaged with the heater.

* Available from the American National Standards
Institute, Inc.,  1430 Broadway, New York, NY
10018 or from the National Fire Protection
Association Inc., Batterymarch Park, Quincy,
MA  02269.

Before servicing the heater, be sure that the
installation conforms to local codes and all safety
precautions outlined in the Owner’s Operation
and Installation Manual. In the absence of local
codes, the installation must conform with the
National Fuel Gas Code, ANSI Z223.1 1984,
and ADDENDA Z223.1a-1987 also known as
NFPA 54*. Only qualified (licensed or trained)
persons should install the product.

Location: Safety Precautions

Be sure that the following safety precautions
have been followed for locating the heater:
1.

DO NOT install the heater in sleeping quar-
ters, mobile homes or recreational vehicles.

2.

DO NOT install heater as a fireplace insert.

3.

The heater should be located to give easy
access for operation, servicing and inspec-
tion.

4.

DO NOT install in areas where curtains,
drapes, clothing or other flammable materi-
als are within 36 inches of the front, top and
sides of the heater.

5.

This heater has been designed for wall
mounting. The clearances from the heater
to combustible surfaces MUST NOT be
less than shown in Figure 7. These are
absolute minimum clearances. Greater
clearances should be allowed if possible.
The heater can also be mounted to an
optional floor mounting base that is sold as
a separate accessory. If a base accessory
is used, be sure the base is securely at-
tached to the floor.

If the heater is installed in a residential garage,
the following precautions should be taken:
1.

The heater pilot and burners must be at
least 18 inches above the floor.

2.

The heater must be located or reasonably
protected, so as not to be subjected to
damage by a moving vehicle.

Wall or Base Mounting

See Owner’s Manual for detailed instructions for
wall or base mounting.

Gas Type

Be sure that the type of gas supplied to the
heater is the same as that indicated on the
heater data plate. If you observe that the gas
supply is different than that specified on the
heater data plate, DO NOT operate the heater
until the correct gas supply is installed. Verify
that the regulator, burner orifices, and pilot as-

sembly are for the same gas type as is indicated
on the heater data plate (see 

“SPECIFICA-

TIONS”, page 13). DO NOT attempt to convert
a heater from one gas type to another (i.e.,
Propane to Natural Gas or vice versa). If neces-
sary, replace the heater with a model suitable for
the type of gas being supplied.
