Gas Pressure
Requirements
Pressure requirements for Heat-N-Glo gas appliances
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 outlet side of the gas control for a test
gauge connection to measure the manifold pressure. To
measure inlet pressure, provisions must be made to
attach a test gauge to a one-eighth (1/8) inch (3 mm)
N.P.T. plugged tapping immediately upstream of the gas
supply connection to the fireplace. On some models
there may be a tap for the manifold and inlet pressure
on the face of the valve. 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).
