Installation Instructions and Owner’s Manual - L48
ENGLISH
Installing a New Shut-Off Valve
Each fireplace should have its own manual
gas shut-off valve. A manual main gas shut-
off valve should be located in the vicinity of
the fireplace. Where none exists, or where its
size or location is not adequate, contact your
local authorized installer for installation or
relocation.
Compounds used on threaded joints of gas
piping shall be resistant to the action of
liquefied petroleum gases. The gas lines must
be checked for leaks by the installer. This
should be done with a soap solution watching
for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed flame to check for
leaks. Fireplace must be disconnected
from piping at inlet of control valve and
pipe capped or plugged for pressure test.
Never pressure test with fireplace
connected; control valve will sustain
damage!
NOTICE:
The gas control is equipped with
a captured screw type pressure test point,
therefore it is not necessary to provide a 1/8
inch test point up stream of the control. See
.
When using copper or flex connector use
only approved fittings. The fireplace and it’s
individual shut-off valve must be disconnected
from supply piping system during any pressure
testing of that system at test pressures in
excess of 1/2 psig (3.5 kPa).
The fireplace must be isolated from the gas
supply piping system by closing its individual
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 (3.5
kPa).
Checking Manifold Pressures
Both Propane and Natural Gas valves have a
built-in pressure regulator in the gas valve.
Natural Gas models will have a manifold
pressure of approximately 3.5-in w.c. (.871
kPa) at the valve outlet with the inlet pressure to
the valve from a minimum of 4.5-in w.c. (1.120
kPa) for the purpose of input adjustment to a
maximum of 14.0-in w.c. (3.484 kPa).
Propane Gas models will have a manifold
pressure approximately 10.0-in w.c. (2.49 kPa)
at the valve outlet with the inlet pressure to
the valve from a minimum of 10.8-in w.c. (2.68
kPa) for the purpose of input adjustment to a
maximum of 14.0-in w.c. (3.484 kPa).
CAUTION
If one of the procedures results
in pressures in excess of 1/2 psig
(14-in w.c.) (3.5 kPa) on the fire-
place gas valve, it will result in a
hazardous condition.

Gas Line Connection
Remove the access panel from the right side
of the fireplace shown in
the gas valve, gas flex line, junction box, and
system wiring.
Attach the gas flex line to the pre-installed
gas line. Refer to the Gas Supply section in
this manual for details on the installation
requirements for the gas supply line.
