Test gauge connections are provided on the front
of the gas control valve; identified IN for the inlet
and OUT for the manifold side (see Figure 1).
The appliance and its appliance main gas
valve must be disconnected from the gas
supply piping system during any pressure
testing of that system at test pressures in
excess of 1/2 psi (3.5 kPa).

PURGE CYCLE
This is a power vented fireplace that
requires household electrical power
to operate. It will not operate during
a power failure. When the fireplace
is turned off, the exhaust blower will
continue to operate for approximately
fifteen (15) seconds after shutdown
to expel the exhaust gases from the
Propane Gas
venting system.
