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.
Main burner goes out;
pilot stays on.
Pilot fl ame is not large enough or
not engulfi ng the thermopile.
-
Turn up the pilot fl ame.
-
Replace pilot assembly.
Thermopile shorting.
-
Clean thermopile connection to the valve. Reconnect.
-
Replace thermopile / valve.
Remote wall switch wire is too
long; too much resistance in the
system.
-
Shorten wire to correct length or wire gauge.
Faulty thermostat or switch.
-
Replace.
Main burner goes out;
pilot goes out.
Refer to “MAIN BURNER GOES OUT; PILOT STAYS ON”
Vent is blocked
-
Check for vent blockage.

-
Check joint seals and installation
Flexible vent has become
disconnected from appliance.
-
Re-attach to appliance.
-
Cap was not replaced.
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.
Air shutter improperly adjusted.
-
Return air shutter to specifi ed opening, see “venturi adjustment” section.
Carbon is being
deposited on glass,
logs, rocks, media or
combustion chamber
surfaces.
Air shutter is blocked.
-
Ensure air shutter opening is free of lint or other obstructions.
Flame is impinging on the
glass, logs, rocks, media or
combustion chamber.
-
Ensure the media is positioned correctly in the appliance.
-
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.
-
Ensure door gasketing is not broken or missing and the seal is tight.
-
Ensure 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.
Exhaust fumes smelled
in room, headaches.
Appliance is spilling.
(This is not applicable in outdoor
