High Elevations

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/NFPA 54 and/or local codes
having jurisdiction.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370 m).

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 conve-
nient locations to allow for the gas pipe installation and
testing of any gas connection.
The gas line connection can be made with properly
tinned 3/8" copper tubing, 1/2" rigid pipe or an approved
flex connector. Since some municipalities have addi-
tional local codes, it is always best to consult your local
authority and the CSA-B149.1 installation codes.
For USA installations consult the current National Fuel
Gas Code, ANSI Z223.1/NFPA 54.

Fig. 6 Typical gas supply installation.
Always check for gas leaks with a mild
soap and water solution applied with a
brush no larger than 1" (25 mm). Never
apply soap and water solution with a spray
bottle. Do not use an open flame for leak
testing.
The fireplace valve must not be subjected
to any test pressures exceeding 1/2 psi.
Isolate or disconnect this or any other gas
appliance control from the gas line when
pressure testing.

The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to pro-
vide a 1/8" test point up stream of the control.
When using copper or flex connector use only approved
fittings. Always provide a union when using black iron
pipe so that the gas line can be easily disconnected for
burner or fan servicing. (Fig. 6) See the gas specifica-
tions for pressure details and ratings.

Remote ON/OFF Switch Installation

Do not wire the remote ON/OFF wall switch for this gas
appliance into a 120v power supply.
1. Thread wire through the electrical knockout located
on either side of the unit. Take care not to cut the
wire or insulation on metal edges. Ensure the wire is
secured and protected from possible damage. Run
one end of the gas control valve and the other end to
the conveniently located wall switch.
2. Attach the wire to the ON/OFF switch and install
switch into receptacle box. Attach cover plate to
switch.
3. Connect wiring to gas valve. (Fig. 7)
