PROBLEM
No spark at pilot burner.
THERMOPILE
Out of propane gas.
Spark gap is incorrect.
No gas at the pilot burner.
Unit is over-fi red or underfi red.
B A
*MAXIMUM INLET PRESSURE NOT TO EXCEED 13"
Door is ajar.
Venting action is too
great.
Air shutter has become
blocked.
Flame is impinging on the logs
or combustion chamber.
TEST SOLUTiON
Check if pilot can be lit by a match.
-
- Check that the wire is connected to the push button
igniter.
Check if the push button igniter needs tightening.
-
Replace the wire if the wire insulation is broken or frayed.
-
Replace the electrode if the ceramic insulator is cracked
-
or broken.
- Replace the push button ignitor
Fill the tank.
-
Spark gap should be 0.150" (3.8mm) to 0.175" (4.5mm)
-
from the electrode tip and the pilot burner. To ensure
proper electrode location, tighten securing nut (fi nger
tight plus 1/4 turn).
Check that the manual valve is turned on.
-
Check the pilot orifi ce for blockage.
-
Replace the valve.
-
Call the gas distributor.
-
Check pressure readings:
-
Inlet pressure can be checked by turning screw (A)
-
counter-clockwise 2 or 3 turns and then placing
pressure gauge tubing over the test point. Gauge
should read as described on the chart below. Check
with main burner is operating on 'hI'.
Outlet pressure can be checked the same as above
-
using screw (B). Gauge should read as described on
the chart below. Check that main burner is operating on
'hI'.
AFTER TAkING PRESSURE READINGS, BE SURE TO
-
TURN SCREWS CLOCkWISE FIRMLy TO RESEAL. DO
NOT OVER TORQUE.
Leak test with a soap and water solution.

Ensure the mechanical means of securing the door is
-
providing a tight seal.
- Check to ensure venting is properly sealed.
If restriction is required see "RESTRICTING VERTICAL
-
VENT" section.
Ensure air shutter opening is free of lint or other
-
obstructions.
Check that the logs 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 values.
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 (meter) has been
-
adhered to for any horizontal venting.
