“FIRST TIME” PILOT LIGHTING INSTRUCTIONS 
IMPORTANT:

  Be sure all items on "INSTALLATION CHECK OFF LIST" in the Installation Manual have been completed! 

CAUTION:

  If the pilot goes out, be sure to wait a minimum of five minutes before attempting to relight the pilot. 

Make certain that any manual gas supply shut-off valves located upstream of fireplace are open and the Master On/Off 
switch is toggled to the ON position.   
Make certain that 110VAC power is connected to Electrical Junction Box on left side of Fireplace and that the Electrical 
Power is “ON”. 
Insert Batteries in the Remote Transmitter. Note the polarity of batteries and 
insert as indicated on the battery compartment cover. 
For the “First Time Lighting”, Remove the Glass Door. This is required to 
purge the gas line of air and to inspect the pilot lighting spark. 
Press OFF on the remote Transmitter. Press MODE button on Transmitter. 
Press UP for “CPI” (standing pilot mode). Press MODE button again to exit. 
You will hear a series of clicks and after a few seconds, you will hear spark-
ing at the pilot spark electrode. 
Allow adequate time for the air in the gas-line to purge. The control system 
will stop sparking after 30 seconds if the pilot light does not light. After a 30 
second delay the control system will start sparking again for 30 seconds 
more.  If the pilot light does not light after the third 30 second spark event, 
the system will enter “Lock-out” mode. To unlock from “Lock-out” mode, 
Press the ON/OFF button on Transmitter then Press ON/OFF button on the transmitter again so the Transmitter display 
turns off. Wait 30 seconds. Turn OFF the Master Switch. Wait 30 seconds and Turn Master Switch ON again. Repeat this 
sequence until the pilot flame lights and the pilot is burning steadily.  

Once the pilot flame is lit and well-established, close glass door.  WARNING: NEVER IGNITE MAIN BURNERS WITH 
GLASS DOOR REMOVED OR OPEN. Doing so will lead to damage to pilot flame sensor and spark electrode wire leads. 

Press the ON/OFF button on Transmitter to “ON”. All burners should ignite and 
run at “high-fire”.  Toggle through other functions of the Fireplace (Flame 
Height, Fan Speed and Accent Light brightness) to verify all functions. 

Perform gas inlet and outlet pressure tests and leak tests on field installed gas 
fittings and factory installed fittings in the gas valve compartment, at this time. 
Note: Burners must be ON to check outlet pressures and to leak test gas train 
fittings upstream of main gas valve. 

INITIALIZING THE REMOTE CONTROL SYSTEM 

MASTER SWITCH: Remote Transmitter WILL NOT communicate to receiver 
unless the Master Switch is ON. The master switch when OFF disable all 
functions and acts as a Master Safety Shutoff Switch. 

(Synchronizing Receiver and Transmitter) 
Master Switch and Sync Switch are located at the bottom left corner of the 
Glass Frame. 

Toggle Master Switch to ON (pull toward front of unit). Remote Transmitter 
WILL NOT communicate to receiver unless the Master Switch is ON. 

Locate Sync Switch (directly above Master Switch). Press the Sync Button. The receiver will beep 3 times indicating that it 
is ready to synchronize with a Remote Transmitter. 

Push the “ON” key on the Remote Transmitter. The receiver will beep 4 times to indicate that the Transmitter’s command 
is accepted and sets to the particular code of that Transmitter.  The system is now initialized. 

NOTE

: Once synchronized, the Transmitter and Receivers will communicate permanently and no further Synchronizing 

steps are necessary unless either the Transmitter or Receiver is replaced.
