Installation Cod s
The fireplace installation must conform to local codes. Before installing the
fireplace, consult the local building code agency to ensure that you are in
compliance with all applicable codes, including permits and inspections.
In the absence of local codes, the fireplace installation must conform to the
National Fuel Gas Code ANSI Z 3.1 (in the United States) or the CAN/CGA-
B149 Installation Codes (in Canada). The appliance must be electrically
grounded in accordance with local codes or, in the absence of local codes with
the National Electric Code ANSI/NFPA No. 70 (in the United States), or to the
CSA C .1Canadian Electric Code (in Canada).
These models may be installed in a bedroom or bed-sitting room in the U.S.A.
and Canada.

High Altitud Installations
U.L. Listed gas fireplaces are tested and approved for elevations from 0 to
,000 feet in the U. S. A. and from 0 to 4,500 feet in Canada.
When installing this fireplace at an elevation above ,000 feet (in the United
States), it may be necessary to decrease the input rating by changing the
existing burner orifice to a smaller size. Input should be reduced four percent
(4%) for each 1,000 feet above sea level, unless the heating value of the gas
has been reduced, in which case this general rule will not apply. To identify the
proper orifice size, check with the local gas utility.
When installing this fireplace at an elevation between ,000 and 4,500 feet (in
Canada), the input rating must be reduced by ten percent (10%).
When installing this fireplace at an elevation above 4,500 feet (in Canada),
check with local authorities.
Consult your local gas utility for assistance in determining the proper orifice for
your location.

Introducing
Heat-N-Glo
Fireplace

When planning a fireplace installation, its necessary to determine:
Where the unit is to be installed.
The vent system configuration to be used.
Gas supply piping.
Electrical wiring.
Framing and finishing details.
Whether optional accessoriesdevices such as a fan, wall switch, or remote
controlare desired.
If the fireplace is to be installed on carpeting or tile, or on any combustible
material other than wood flooring, the fireplace should be installed on a metal or
wood panel that extends the full width and depth of the fireplace.
The CFK-SL36 Clean Face Kit is designed to convert a Model SL-36 Gas
Fireplace to a Clean Face Design. The kit includes a top extension piece, an
upper grille cover, and a lower grille cover. See Figure . The following
requirements MUST be met if this kit is installed. IF THESE REQUIREMENTS
ARE NOT MET, A POTENTIAL FIRE HAZARD WILL EXIST AND THE
FIREPLACE WARRANTY WILL BE VOIDED.
1. The first vent component attached to the fireplace starting collar MUST be
a 3-foot (904 mm) length of straight pipe.
. The top extension piece in this kit MUST be properly installed to avoid a fire
hazard.
3. The lower fireplace grille MUST be able to be opened for access to the gas
valve and controls. This condition MUST be met after the Clean Face Kit is
installed and the fireplace finishing has been completed.
4. An optional fan (kit no. GFK-160A or any other fan) CANNOT be installed in
the SL-36 fireplace when converted to a clean face fireplace.
5. Damaged components or components field-modified without factory autho-
rization cannot be installed or used. Installation instructions are included in
the CFK-SL36 Kit.
