SYMPTOM PROBLEM TEST SOLUTION
Main burner fl ame
is a blue, lazy,
transparent fl ame. Blockage in vent. - Remove blockage. In really cold conditions, ice buildup may
occur on the terminal and should be removed as required.
To minimize this from happening again, it is recommended
that the vent lengths that pass through unheated spaces
(attics, garages, crawl spaces) be wrapped with an
insulated mylar sleeve. Prevent sleeve from sagging.
Contact your local authorized dealer for more information.
Incorrect installation. - Refer to “VENTING” section to ensure correct installation.
Flames are
consistently too
large or too small.
Carboning occurs. Appliance is over-fi red or
underfi red. - 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 that 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.
Carbon is being
deposited on glass,
logs, rocks, media
or combustion
chamber surfaces. Air shutter has become
blocked. - Ensure air shutter opening is free of lint or other
obstructions.
Flame is impinging on the
glass, logs, rocks, media or
combustion chamber. - Check that the glass, logs, rocks, 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 (meters) has been
adhered to for any horizontal venting.
White / grey fi lm
forms. Sulphur from fuel is being
deposited on glass, logs
or combustion chamber
surfaces. - Clean the glass with a recommended gas fi replace glass
cleaner. DO NOT CLEAN GLASS WHEN HOT.
- If deposits are not cleaned off regularly, the glass may
become permanently marked.
No spark after pilot
ignition. Valve turns
off in one minute
and does not
operate. Minimal voltage from
thermocouple or resistance
in circuit (Parts resulting in
resistance include: “ON/
OFF” switch, receiver,
thermocurrent connections
or temperature switches). - Measure the voltage, it should read a least 5mV. The spade
connector is on the outer surface beside the magnet nut.
Verify with manufacturer the drop time, after thermocouple
is heated measure the drop time.

WARNING
ALWAYS LIGHT THE PILOT WHETHER FOR THE FIRST TIME OR IF THE GAS SUPPLY HAS RAN OUT,
WITH THE GLASS DOOR OPEN OR REMOVED.
TURN OFF THE GAS AND ELECTRICAL POWER BEFORE SERVICING THE APPLIANCE.
