W415-0687 / G / 08.26.13
PROBLEM
Gas supply.
Module is not grounded.
Out of propane gas.
Short or loose connection
in sensor rod.
Poor fl ame rectifi cation or
contaminated sensor rod.
Poor grounding between
pilot assembly and gas
valve.
Damaged pilot or dirty
sensor rod.
Pilot has been painted
Receiver switch is in the
wrong position.
No power to the system.
Transmitter isn't
operational.
Control module switch is
in the wrong position.
COM switch is unplugged.
TEST SOLUTION
- 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 14"
W.C. (34.9mb).
- Verify the value and pilot assemblies are properly
grounded to the metal chassis of the fi replace.
- Fill the tank.
Verify all connections. Verify the connections from the
pilot assembly are tight; also verify these connections
are not grounding out to any metal.
- Verify the fl ame is engulfi ng the sensor rod. This
will increase the fl ame rectifi cation. Verify correct
pilot orifi ce is installed and inlet gas specifi cations
to manual. (Remember, the fl ame carries the
rectifi cation current, not the gas. If the fl ame lifts from
pilot hood, the circuit is broken. A wrong orifi ce or too
high of an inlet pressure can cause the pilot fl ame to
lift.) The sensor rod may need cleaning.
- Verify that the wire harness is fi rmly connected to
module.
- Verify that the ceramic insulator around the sensor
rod is not cracked, damaged, or loose. Verify the
connection from the sensor rod to the sensor wire.
Clean sensor rod with an emery cloth to remove
any contamination that may have accumulated on
the sensor rod. Verify continuity with multimeter with
ohms set at the lowest range.
- Using a piece of sandpaper or emery cloth remove
the paint from the pilot hood, ignitor and fl ame sensor.
- Verify that the 3 position switch on the receiver is in
the "REMOTE" position (middle).
- Check breaker to verify it's in the "ON" position.
- Check battery power and battery orientation.
- Verify ON/OFF switch is in the "I" position which
denotes on.
- Verify "COM" switch is plugged into the front of the
control module.
