WARNING
Fire Risk
Explosion Risk
High pressure will damage valve.
• Disconnect gas supply piping BEFORE
pressure testing gas line at test pressures
above 60 mbar.
• Close the manual shutoff valve BEFORE
pressure testing gas line at test pressures
equal to or less than 60 mbar.
A. Gas Pressure Requirements
Pressure requirements for Heat & Glo gas fi replaces are
shown in Table 1 below.
Two taps are provided on the outlet side of the gas control
for a test gauge connection to measure the inlet and outlet
pressures. These inlet and outlet pressure taps can be ac-
cessed through the internal valve access panels as shown
in Section 11: Maintaining and Servicing the Fireplace.
The fi replace and its individual shut-off valve must be dis-
connected from the gas supply piping system during any
pressure testing of the system at test pressures in excess
of 60 mbar.
If the fi replace must be isolated from the gas supply piping
system by closing an individual shut-off valve, it must be of
the handle-less type.
B. Gas Connection
Note: Have the gas supply line installed in accordance
with local building codes by a qualified installer
approved and/or licensed as required by the locality.

Incoming gas line should be piped into the valve compart-
ment and connected to the ISO 7-Rp 1/2 (BSP Rp 1/2)
threaded gas inlet connection on the manual shutoff valve.
Note: Before the fi rst fi ring of the fi replace, the gas
supply line should be purged of any trapped air.
Note: Consult local building regulations to properly
size the gas supply line leading to the (Rp 1/2 in.)
hook-up at the unit.
