During any pressure testing of the gas line system,
when the test pressures are to exceed 1/2 psi (3.5 kpa)
the fireplace and its gas valve must not be connected
to that system.
At test pressures equal to or less than 1/2 psi, the gas
valve of the fireplace may be connected to the gas line,
but must be in the closed position.
Some municipalities have additional local codes, it is
always best to consult the local authority and the CSA-
B149.1 installation code in Canada.
FOR U.S.A Installations consult the current National
Fuel Gas Code, ANSI Z223.1
Always check for gas leaks with a mild soap
and water solution. Do not use an open
flame for leak testing.

cap in it. Remove the plastic cap and connect your gas
supply line at this point.
