At the gas line access hole, use insulation to re-
pack the space around the gas pipe.
Insert insulation from the outside of the fireplace
and pack the insulation tightly to totally seal be-
tween the pipe and the outer casing.
The gas line should be
installed by a qualified
service technician.

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 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.
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).
