Gas Pressure
Requirements
Pressure requirements for Heat-N-Glo gas fireplaces
are shown in the table below.
Pressure Natural Gas Propane
Minimum 5.0 inches 11.0 inches
Inlet Pressure w.c. w.c.
Maximum Inlet 14.0 inches 14.0 inches
Gas Pressure w.c. w.c.
Manifold 3.5 inches 10.0 inches
Pressure w.c. w.c.
A one-eighth (1/8) inch (3 mm) N.P.T. plugged
tapping is provided on the inlet and outlet side of the
gas control for a test gauge connection to measure
the manifold pressure. Use a small flat blade
screwdriver to crack open the screw in the center
of the tap. Position a rubber hose over the tap to
obtain the pressure reading.
The fireplace and its individual shut-off valve must
be disconnected from the gas supply piping system
during any pressure testing of the system at test
pressures in excess of one-half (1/2) psig (3.5 kPa).
The fireplace must be isolated from the gas supply
piping system by closing its individual shut-off valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than one-
half (1/2) psig (3.5 kPa).
