NOTE: Starting from OFF, press the ON button on the transmitter. Approximately 4
seconds after the ON/OFF button is pressed the ignition board will start the spark. The
first try for ignition will last approximately 60 seconds. If there is no flame ignition
(rectification) the board will stop sparking for approximately 35 seconds. After the wait
time the board will start the second try for ignition by sparking for approximately 60
seconds. If there is still no positive ignition, the board will go into lock out.
TEST SOLUTION
- Ensure exhaust bracket gasket seal.
- Check door seal.
- Check for exhaust blockage.
- Check that venting is installed correctly.
- Room is in negative pressure; increase fresh air supply.
- Verify the wire for the sensor and the wire for the ignitor
are connected to the correct terminals (not reverse) on
the module and pilot assembly.
- Verify no loose connections, electrical shorts in the
wiring or ground out to any metal object.
- Spark gap of the ignitor to the pilot should be .125"
(1/8").
- Remove and reinstall the wiring harness that plugs into
the module.
- Remove and verify continuity of each wire in the wiring
harness.
- Verify the valve and pilot assemblies are properly
grounded to the metal chassis of the fireplace.
