Cold climate installation recommendation:
When installing this unit against a non-
insulated exterior wall or chase, it is
mandatory that the outer walls be insulated
to conform to applicable insulation codes.
Hearth
A hearth is not mandatory but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth which projects out 12” (305 mm) or more from
the front of the fireplace.
Framing and Finishing
Check fireplace to make sure it is levelled
and properly positioned.
To mount the appliance:
1. Choose the location.
2. Nailing flanges are supplied with the fireplace (found
on the fireplace hearth). To level the box and secure
it firmly in place, remove the nailing flanges from
the hearth and install at the sides of the fireplace as
shown in Figure 5.

For elevations above 4,500 feet (1,370m) in USA,
installations must be in accordance with the
current ANSI Z223.1/NFPA 54 and/or local codes
having jurisdiction.
In Canada, please consult provincial and/or local

Gas Line Installation
When purging gas line the front glass must
be removed.
The gas pipeline can be brought in through the right
side of the appliance. Knockouts are provided at con-
venient locations to allow for the gas pipe installation
and testing of any gas connection.
The gas line connection can be made with 3/8” copper
tubing, 1/2” rigid pipe or an approved flex connector.
Since some municipalities have additional local codes,
it is always best to consult your local authority and the
CSA-B149.1 installation codes. For US installations
consult the current National Fuel Gas Code, ANSI
Z223.1/NFPA 54.
