First Time" Pilot Lighting Instructions - Mendota DXV-45 DT3-LX Operating Instructions Manual

"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.
1. Make certain that any manual gas supply shut-off valves located upstream of fireplace are open and the receiver and
the remote control transmitter are in the "OFF" position. Make certain that the receiver harness is connected to the
wall receiver properly.
2. Make certain that 110VAC power is connected to Electrical Junction Box on right side of Fireplace and that the Elec-
trical Power is "ON".
3. Insert Batteries in the Receiver and the Remote Transmitter. Note the polarity of batteries and insert as indicated on
the battery compartment covers.
4. 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.
5. Slide the receiver switch to "REMOTE". Locate the "Standing Pilot ON/OFF Switch".
6. Toggle "Standing Pilot ON/OFF Switch" to "ON". You will hear a series of clicks and after a few seconds, you will hear
sparking at the pilot spark electrode.
7. 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, slide Receiver Switch to "OFF" and toggle "Standing Pilot ON/OFF Switch" to "OFF", wait 30
seconds and slide back to "Remote". Repeat this sequence until the pilot flame lights and the pilot is burning steadily.
7. 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 elec-
trode wire leads.
8. Slide switch on Receiver to "ON". All burners should ignite and run at "high-fire". Slide Receiver switch to REMOTE
after 15 seconds. Burner Flames will extinguish.
9. 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
(Synchronizing Receiver and Transmitter)
1. Place 3-position slider switch in Receiver in the "Remote" position.
2. Locate "PRG" key on Receiver Face. Use the tip of a pen/pencil or a wire clip to push the PRG button. The receiver
will beep 3 times indicating that it is ready to synchronize with a Remote Transmitter.
3. Push the "ON" key on the Remote Transmitter. The receiver will beep 4 times to indicate that the Transmitter's com-
mand is accepted and sets to the particular code of that Transmitter. The system is now initialized.
NOTE: Use this Synchronizing procedure every time the batteries are replaced in the Receiver or the Transmitter.
