7.1 Gas Supply Connection
The gas supply line connection is made to the valve on
the left side of the unit facing the front. The gas supply
line should be a minimum of 3/8” in diameter, or the
appropriate size to provide sufficient gas pressure to the
valve regardless of the input setting. See fig. 7.1-7.2.
This appliance is shipped with a 36” length of
3/8” flexible gas line
to ease installation and service.
However, for those areas where flexible gas lines are
not permitted, use of a 3/8” iron nipple and union is
recommended. See fig. 7.1.
The use of Flexible Gas Appliance Connectors is
acceptable in many areas in the U.S., however, Canadian
methods vary depending on local code.
ALL INSTALLATIONS MUST COMPLY WITH LOCAL
CODE OR IN THE ABSENCE OF LOCAL CODE, MUST
COMPLY WITH THE MOST RECENT EDITION OF THE
NATIONAL FUEL GAS CODE ANSI Z223.1/NFPA 54 OR
CAN-B149.
An integrated gas cock must be installed into the
fuel supply line upstream of the valve. This feature
conforms to building codes requiring a shut-off valve be
located within the same room as the appliance. The gas
cock allows for the disconnection of the appliance for
servicing and maintenance. See fig. 7.1.
Secure all joints tightly using appropriate tools
and sealing compounds.
Propane fuel requires sealant
specifically resistant to propane chemical degradation.
INSTALLATION OF A T-HANDLE GAS COCK IS
REQUIRED IN MASSACHUSETTS IN COMPLIANCE
WITH CODE 248 CMR.

7. Fireplace Assembly
Before beginning final assembly, push the insert
partially into the fireplace and adjust the leveling
bolts located at each corner as appropriate to
achieve a level and plumb installation.
Complete assembly procedures 1-5 before placing the
insert within the firepace.

7.2 Gas Pressure
Correct gas pressure is essential for efficient and
safe operation of this appliance. It is important that
the correct pressure is established at the time of the
installation. Proper gas pressure provides a consistent
flow of gas to the appliance and is instrumental in
checking for gas leaks.
Pressure Test:
Attach a manometer to the
appropriate test point on the valve. See fig. 7.2. The
gauge connections are located on the front of the valve.
Connections are identified by:
A - for Inlet or Supply Pressure
(the amount of gas
coming to the valve.)
B - for Manifold Pressure
(the amount of gas that
is coming out of the valve to the burner.)
ALWAYS TEST PRESSURES WITH VALVE REGULATOR
CONTROL KNOB SET ON “HIGH”.
High Altitude Adjustment
The this appliance does not require adjustment for
altitude.
LEAK TEST:
Open the gas supply valve and test for
gas leaks using a soapy water solution or digital
gas sensor.
DO NOT use an open flame to check for
leaks
. Tighten or reconnect any leaking joint and
retest to confirm secure fittings.
