combustion chamber.
Sulphur from fuel is being
deposited on glass, logs or
combustion chamber surfaces.

test solution
-
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.
-
Turn up the pilot fl ame.
-
Replace pilot assembly.
-
Clean thermopile connection to the valve. Reconnect.
-
Replace thermopile / valve.
-
Shorten wire to correct length or wire gauge.
-
Replace.
-
Check for vent blockage.
-
Check joint seals and installation
-
Re-attach to appliance.
-
Cap was not replaced.
-
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.

Return air shutter to specifi ed opening, see "venturi adjustment" section.
-
Ensure air shutter opening is free of lint or other obstructions.
-
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.
-
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.
