Al
ways 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.

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 approved flex connector. Since
some municipalities have some additional
local codes, it is always best to consult your
local authority and the CAN/CGA- B149 (.1 or
.2) installation code.
