Installing a New Main Gas Shut-Off Valve
Each appliance must have its own manual gas shut-off valve
located in close proximity. Where none exists, or where its size
or location is not adequate, contact your local authorized installer
for replacement or relocation.
Test For Leaks On Exposed Connections
Never use an exposed flame to check for leaks.
Turn Off the Fireplace. Compounds used on threaded joints of
gas piping must be resistant to the action of liquefied petroleum
gases. Check all gas connections for leaks with a leak test
solution or soap solution. Rinse off all of the solution after testing.
DO NOT get solution on electronic controls.
Test For Leaks On Unexposed Connections
Perform a pressure test on all unexposed connections.
Never pressure test with fireplace connected; control valve will
sustain damage. Disconnect the fireplace from piping at the
control valve inlet and cap the pipe before pressure testing.
NOTICE: The IP valve is equipped with a captured screw type
pressure test port, therefore it is not necessary to provide a test
point upstream.
Disconnect the appliance and its individual shut-off valve from
the gas supply piping system before any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5kPa).
Isolate the appliance from the gas supply piping system by
closing its manual shut off valve during any pressure testing of
the gas supply piping system at test pressures equal to or less
than 1/2 psig (3.5kPa).
If one of the procedures results in pressures in excess of
1/2 psig (14-inch w.c.) (3.5 kPa) on the fireplace gas valve, it
will result in a hazardous condition.
All wiring should be done by a qualified electrician and shall be in compliance with all local, city and state building codes.
Before making the electrical connection make sure the main power supply is disconnected. The appliance, when installed,
must be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical
Code ANSI/NFPA70 (Latest Edition).

Checking Manifold Pressures
Both Propane and Natural Gas valves have a built-in pressure
regulator.
Natural Gas models will have a manifold pressure of
approximately 3.5-inch w.c. (.871kPa) at the valve outlet with
the inlet pressure to the valve from a minimum of 4.5-inch w.c.
(1.120kPa) for the purpose of input adjustment to a maximum of
14.0-inch w.c. (3.484kPa).
Propane models will have a manifold pressure of approximately
10.0-inch w.c. (2.49kPa) at the valve outlet with the inlet pressure
to the valve from a minimum of 10.8-inch w.c. (2.68kPa) for the
purpose of input adjustment to a maximum of 14.0-inch w.c.
(3.484kPa).
