Preparation
The use of wallpaper adjacent to this fireplace is not
recommended, as the high heat given off by this fire-
place 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. Refer to Window
Frame Assembly Removal Section.

Gas Line Installation
When purging gas line, the front window
frame assembly must be removed.
The gas pipeline can be brought in through the rear
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 connection.
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 ap-
proved flex connector. Since some municipalities 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 installa-
tion codes.
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 neces-
sary to provide 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 . See gas specifications for pres-
sure 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.
