Orifice
Changing Pilot Orifice
The pilot is provided with a natural gas
orifice installed. For propane/LP gas you
must remove it and replace it with a pro-
pane/LP orifice. The hardware kit contains
an propane/LP orifice with a red stripe for
converting the pilot.
1. Gently loosen and remove the pilot
line connection from the bracket (see
Figure 18).
2. Replace the orifice (see Figure 18) with
the propane/LP pilot orifice with the
red stripe.
3. Replace and tighten the pilot line to the
bracket.
4. Continue with step 7 under Hearth Kit
Assembly and Installation, page 9.
Note:
Follow the instructions under the sec-
tion, Testing Burner for Leaks, column 3.
REMOTE CONTROL OPTIONS
GHRC
If you are using the GHRC remote control
option, you must first connect the leads of
the receiver to the terminal block on the gas
control (see Figure 19).
1. Connect the leads to the male fast-on
terminals marked TH and TPTH.
2. Install a 9V battery (refer to the instruc-
tions included with the GHRC).
3. Install a 9V battery into the hand-held
transmitter.
4. Insert the receiver into the simulated
log control cover, with the raised cyl-
inder fitting into the hole in the cover.
5. The cover may be moved aside when
operation of the gas control is necessary.

Valve
GWMS2
When installing the GWMS2 remote wall
switch option, follow all instructions in-
cluded with the accessory. Connect wires as
shown in Figure 19. You will need to route
the wiring away from the gas control and log
set in a way which prevents direct radiant
heat on the wires.
No Optional Accessories
If you choose no remote accessories at this
time, the provided jumper wire must be
installed to the terminal block on the gas
control. Connect the lead to the fast-on
terminals marked TH and TPTH.
TESTING BURNER FOR
LEAKS
1. Generously apply soapy solution to all
connections.
WARNING: Never check for
gas leaks with open flame.
2. Light the burner with the shut-off valve
no more than half open and holding a
match slightly in front of the pan (see
Lighting Instructions, page 13).
3. Inspect all connections for bubbles, raw
gas odor, or flame from any area other
than the burner (leaks). If leaks are de-
tected, shut off the gas valve immedi-
ately. Tighten, or reassemble the loose
connection(s) using pipe joint com-
pound until burner system is leak free.
4. When the burner is tested and leak free,
observe the individual tongues of flame
on the burner.
Note:
The burner design
includes more ports on the outside of the
bar. Make sure that all ports are clear
and producing flame evenly across the
burner. If any ports appear blocked, clear
them by removing the burner manifold
and reaming the ports with a modified
paper clip or other suitable tool.
5. When finished testing, turn the gas shut-
off valve OFF to extinguish all flames.
