High Elevations
Input ratings are shown in BTU per hour and are
certified without deration for elevations up to
4,500 feet (1,370m) above sea level.
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
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370m).

Gas Line Installation
When purging the gas lines, the front glass
must be removed.
The gas pipeline can be brought in through the side and
back of the fireplace as well as the bottom. Knockouts
are provided on the bottom behind the valve to allow for
the gas pipe installation and testing of any gas connec-
tion. It is most convenient to bring the gas line in from
the 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 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.
Always check for gas leaks with a mild
soap and water solution. Do not use an
open flame for leak testing.

Typical gas supply installation.
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 the gas line can be easily disconnected for
burner or fan servicing. Refer to the gas specification
for pressure details and ratings.
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.
