Figure 30. Gas Supply Line
Step 6. The Gas Supply Line
NOTE: Have the gas supply line installed by a qualified
service technician in accordance with all building
codes. (In the Commonwealth of Massachusetts
installation must be performed by a licensed plumber
or gas fitter).
NOTE: Before the first firing of the fireplace, the gas
supply line should be purged of any trapped air.
NOTE: Consult local building codes to properly size
the gas supply line leading to the 3/8 inch (9.5mm)
hook-up at the unit.
This gas fireplace is designed to accept a 3/8 inch (9.5mm)
gas supply line. To install the gas supply line:
• All codes require a listed shut off valve mounted in the
supply line.
• When using copper or flex connector use only listed
fittings. Always provide a union so that gas line can
be easily disconnected for burner or fan servicing (see
Figure 30). NOTE: The use of copper is not approved by
the Commonwealth of Massachusetts.
• Locate the gas line access hole in the outer casing of
the fireplace.
• The gas line may be run from either side of the fireplace
provided the hole in the outer wrap does not exceed 2” in
diameter and it does not penetrate the actual firebox.
• Open the fireplace lower grille, insert the gas supply line
through the gas line hole, and connect it to the shut-off
valve.
• When attaching the pipe, support the control so that the
lines are not bent or torn.
• After the gas line installation is complete, all connec-
tions must be tightened and checked for leaks with a
commercially-available, non-corrosive leak check solu-
tion. Be sure to rinse off all leak check solution following
testing.
Warning: DO NOT USE AN OPEN FLAME TO
CHECK FOR GAS LEAKS.
• Insert insulation from the outside of the fireplace and
pack the insulation tightly to totally seal between the
pipe and the outer casing.
• At the gas line access hole the gap between the supply
piping and gas access hole can be plugged with non-
combustible insulation to prevent cold air infiltration.

Step 7. Gas Pressure Requirements
Pressure requirements for Hearth & Home Technologies
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).
