PREPARATION
GAS LINE INSTALLATION
The use of wall paper adjacent to this
fireplace is not recommended, as the
high heat given off by this fireplace may
adversely affect the binders in the
adhesive used to apply the wallpaper.
Before beginning, remove the window frame assembly
from the fireplace. Also check to make sure there is not
hidden damage to the fireplace. Take a minute and
plan out the gas, vent and electrical supply. See
Window Frame Assembly Section.
When purging the gas line, the front
glass must be removed.
The gas pipeline can be brought in through the rear of
the fireplace as well as the bottom. Opening is provided
on the bottom behind the valve to allow for the gas pipe
installation and testing of any gas connecion. It is most
convenient to bring the gas line in from the rear right
side of the valve, as this allows fan installation or
removal without disconnecting the gas line.
The gas line connection can be made
with properly tinned 3/8” copper tubing,
3/8” rigid pipe or an approved flex con-
nector. Since some municipalities have
some additional local codes, it is always
best to consult your local authority and
the CSA-B149 (.1 or .2) installation code.
For USA Installations consult the current
National Fuel Gas Code, ANSI Z223.1.
Always check for gas leaks with a mild
soap and water solution. Do not use an
open flame for leak testing.
The gas control is equipped with a
captured screw type pressure test point,
therefore it is not necessary to provide a
1/8” test point up stream of the control.
This appliance may be installed in an aftermarket
permanently located, manufactured (mobile) home,
where not prohibited by local codes.
This appliance is only for use with the type of gas
indicated on the rating plate. This appliance is not
convertible for use with other gases, unless a
certified kit is available and used.

Input ratings are shown in BTU per hour and
are certified without deration for elevations up
to 4,500 feet (1,370 m) above sea level.
For elevations above 4,500 feet (1,370 m) in
USA, installations must be in accordance with
the current ANSI Z223.1 and/or local codes
having jurisdiction.
In Canada, please consult provincial and/or
local authorities having jurisdiction for install-
ations at elevations above 4,500 feet (1,370 m).
