Gas Line Installation

Always remove the front window frame as-
sembly before purging the gas lines.
The gas pipeline can be brought in under the bottom of
the fireplace. The gas line connections will be covered
by bottom trim. Refer to Figure 7 for gas line dimen-
sions. Use 1/2" rigid pipe. When gas line is in place un-
der the fireplace, install supplied 1/2" FPT to 3/8" flare
brass fitting. Connect preinstalled flex line on fireplace
to brass fitting with 3/8" flare fitting on supply line.
The gas line connection can be made with 3/8" rigid
pipe or an approved flex connector. Since some munici-
palities have additional local codes, it is always best to
consult your local authority and the National Fuel Gas
Code, ANSI Z223.1/NFPA 54 in the USA or the CSA-
B149.1 installation code.

Fig. 7 Recommended gas line 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. Never use an open flame for leak
testing.
Never subject the fireplace valve to any
test pressures exceeding 1/2 psi. Always
isolate or disconnect the valve 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 a 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
servicing. See gas specification for pressure details and
ratings.
