White / grey film
forms. Sulphur from fuel is being
deposited on glass, logs or
combustion chamber sur-
faces. - clean the glass with a recommended gas fireplace glass cleaner.
DO NOT CLEAN GLASS WHEN HOT.
If deposits are not cleaned off regularly, the glass may become
permanently marked.
Pilot goes out
while standing;
Main burner is in
'OFF' position. Gas piping is undersized. - turn on all gas appliances and see if pilot flame flutters, dimin-
ishes or extinguishes, especially when main burner ignites. Monitor
appliance supply working pressure.
- check if supply piping size is to code. Correct all undersized piping.
Flames are con-
sistently too large
or too small.
Carboning occurs. - check pressure readings:
Inlet pressure can be checked by turning screw (A) counter-clock-
wise 2 or 3 turns and then placing pressure gauge tubing over the
test point. Gauge should read 7" (minimum 4.5") water column for
natural gas or 13" (11" minimum) water column for propane. Check
that main burner is operating on "HI".
Outlet pressure can be checked the same as above using screw
(B). Gauge should read 3.5" water column for natural gas or 10"
water column for propane. Check that main burner is operating on
"HI".
AFTER TAKING PRESSURE READINGS, BE SURE TO TURN
SCREWS CLOCKWISE FIRMLY TO RESEAL. DO NOT OVERTORQUE.
Leak test with a soap and water solution. Unit is over-fired or under-
fired.
Remote wall
switch is in "OFF"
position; main
burner comes on
when gas knob is
turned to "ON" po-
sition. Wall switch is mounted up-
side down - reverse.
Faulty valve. - replace.
- replace. Remote wall switch is
grounding.
- check for ground (short); repair ground or replace wire. Remote wall switch wire is
grounding.
Carbon is being
deposited on
glass, logs or com-
bustion chamber
surfaces.
Flame is impinging on the
logs or combustion cham-
ber. - check that the logs are correctly positioned.
- open air shutter to increase the primary air.
- check the input rate: check the manifold pressure and orifice size
as specified by the rating plate values.
- check to ensure proper venting action
Air shutter has become
blocked - ensure air shutter opening is free of lint or other obstructions.
Exhaust fumes
smelled in room,
headaches. Fireplace is spilling. - check for chimney blockage
- check that chimney is installed to building code.
- room is in negative pressure; increase fresh air supply.
Main burner flame
is a blue, lazy,
transparent flame. Not enough combustion air - room is in negative pressure; increase fresh air supply
