Shut-off Valve
A shut-off valve must be installed upstream of the
gas control valve. This allows for the disconnection of the
fireplace for servicing and maintenance. See Fig. 6.3.
The fireplace and gas control valve must be disconnected
from the gas supply piping during any pressure testing of

Control Valve Connection
The gas supply line connection to the elbow above
the shut-off valve is made through the inlet in the left
side of the fireplace. The gas supply line should be a
minimum3/8”insidediameter,ortheappropriatesizeto
provide sufficient gas pressure to the valve regardless of
the input setting.
