Step 6. The Gas Supply Line

NOTE: Have the gas supply line installed in accordance
with local building codes by a qualified installer
approved and/or licensed as required by the locality.
(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 1/2 inch
(13 mm) hook-up at the unit.
This gas fireplace is designed to accept a 1/2 inch
(13 mm) gas supply line.
To install the gas supply line:
• A listed (and Commonwealth of Massachusetts approved)
1/2 inch (13mm) tee-handle manual shut-off valve and a
listed flexible gas connector are connected to the 1/2
inch (13mm) inlet of the control valve. NOTE: If substi-
tuting for these components, please consult local codes
for compliance.
• 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 Quadra-Fire gas fireplaces
are shown in the table below.
Pressure Natural Gas
Minimum 5.0 inches
Inlet Pressure
Maximum Inlet 14.0 inches
Gas Pressure
Manifold 3.5 inches
Pressure
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.
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).
