The Control Module and Battery Pack are sensitive to heat. Proper
placement will help keep them from malfunctioning due to excess heat.
See the "Parts List" pictures to see how to properly place the Control
Module and Battery Pack under the Heat Shield. The best location for
the Control Module Assembly is outside of the fireplace – 1. On the
hearth or 2. In a cavity that is accessible next to the fireplace. It is
possible for the Control Module Assembly to be located inside the
fireplace if it is in the far right or left corner close to the front opening of
the fireplace. If nuisance operation problems arise the Control Module
Assembly may have to be moved onto the hearth.
Make sure all gas connection fittings and wire connections are secure and safe for ignition.
Set the Switching Device (Switch on Control Module Heat Shield, Remote Control, or Wall Switch) to
call for heat (ON position).
Watch and listen for a spark at the Pilot Assembly.
Pilot should light within a few seconds (if the pilot does not light within 10 seconds you may have to
bleed the gas line to get the air out of the gas inlet pipe).
Once the pilot lights, the heat sensor (straight rod next to the pilot hood) will heat up and then activate
the gas to the main burner.
When gas begins to flow to the main burner the pilot will light the burner gas and remain in operation
during the operation cycle.
When the switching device is turned to the OFF position the main burner flame and pilot flame will shut
down.
1. Main flame will shut off the cycle back on again.
This could be caused by poorly grounded system. If the system has a bad ground it can cause the valve to
turn off the cycle back on again. Check the Valve and Pilot to insure that they are secure. Also check black
wire to valve for tight connection.
This can be caused by not enough heat to the Sensor Rod causing the system to turn off the cycle back on
again. heck sensor rod to insure it is in the pilot flame and is glowing.
2. Pilot and or Main flame won't light but there is spark at pilot hood
This could be caused by the Orange and or Green wires spades have a poor connection at terminal block.
Remove the wires from valve and tighten the female spades on the wire assembly.
This could be caused by a bad solenoid. To check solenoid remove the wires from the solenoid and check
the Ohms with a multi-meter. The readings should be for Pilot = 0.037ohms.
3. Can hear spark, but no spark is visible at pilot hood.
This could be caused by bad connection of ignition wire at module.
This could be caused by improper spark gap between igniter rod and pilot hood it should be no greater
than 0.25" gap.
This could be caused by cracked ceramic on ignition rod. This would arc at the crack to the nearest ground.
4. Turn system on and there is no spark.
This could be caused by no line power from adapter. Check the adapters output with a multi-meter set on
A/C it should read 3.0+ volts if not check j-box for output. If output at j-box replace the adapter.
This could be caused by no D/C power from batteries. Check the connections from battery pack to the
module. Check output to RED & BLACK wires at spade connections from battery pack with multi-meter on
D/C setting it should be 3.0+ volts. If power present at connections remove the harness plug from module
check RED & BLACK females on harness plug for voltage output. If you have voltage at the spade
connection and none at the plug replace wire harness.
