WARNING
!
TEST SOLUTION
- Verify the "S" wire for the sensor and the "I" wire for the ignitor
are connected to the terminals on the module and pilot assembly.
- Verify no loose connections, electrical shorts in the wiring or
ground out to any metal object.
- Turn the ON/OFF switch to the "OFF" position. Remove the
igniter wire "I" from the module. Place the ON/OFF switch to the
"ON" position. Hold a grounded wire about 3/16" (4.8mm) away
from the "I" terminal on the module. If no spark, the module
must be replaced. If there is a spark, the module is fi ne. Inspect
pilot assembly for a shorted wire or cracked insulator around
the electrode.
- Spark gap of the ignitor to the pilot should be .125" (3.2mm)
- Verify the transformer is installed and plugged into the relay
box. Check voltage of the transformer under load at the spade
connections on the relay box with the ON/OFF switch in the
"ON" position. Acceptable readings of a good transformer are
between 2.8 and 3.4 volts A.C.
- Remove and reinstall the wiring harness that plugs into the module.
Remove and verify continuity of each wire in wiring harness.
- Check batteries.
- Troubleshoot the system with the simplest ON/OFF switch.
- Verify that the incoming gas line ball valve is "Open". Verify that the
inlet pressure reading is within acceptable limits, inlet pressures
must not exceed 7" W.C. (17.4mb) for NG and 13" W.C. (32.4mb)
for LP.
- Fill the tank.
- Ensure air shutter opening is free of lint or other obstructions.
- Ensure air shutter is properly set.
- Check that the glass, logs, rocks or media are correctly positioned.
- Open air shutter to increase the primary air.
- Check the input rate: check the manifold pressure and orifi ce size
as specifi ed by the rating plate.
- Check that the door gasketing is not broken or missing and that
the seal is tight.
- Check that both vent liners are free of holes and well sealed at all
joints.
- Check that minimum rise per foot has been adhered to for any
horizontal venting.
