White / grey film
forms. Sulphur from fuel is being
deposited on glass, logs or
combustion chamber sur-
faces. - clean the glass with a non-abrasive ammonia or vinegar based
glass cleaner. DO NOT CLEAN GLASS WHEN HOT.
If deposits are not cleaned off regularly, the glass may become
permanently marked.
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.

Vent is blocked
Vent is re-circulating
- check for vent blockage.
- check joint seals and installation.
4" flexible vent has become
disconnected from fireplace.
- re-attach to fireplace.
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.

grounding.
- check for ground (short); repair ground or replace wire. Remote wall switch wire is
grounding.
Main burner flame
is a blue, lazy,
transparent flame. Blockage in vent. - remove blockage. In really cold conditions, ice buildup may occur
on the terminal and should be removed as required.
- refer to Figure 13 to ensure correct location of storm collars.
Incorrect installation.
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 that the door gasketing is not broken or missing and that the
seal is tight.
- check that both 4" and 7" vent liners are free of holes and well
sealed at all joints.
- check that minimum rise per foor has been adhered to for any
horizontal venting.
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 door seal and relief flap seal.
- check for chimney blockage
- check that chimney is installed to building code.
- room is in negative pressure; increase fresh air supply.
Flames are very
aggressive.
Venting action is too great.
- tighten screws holding door in place
- remove combustion air deflector
from the burner
Door is ajar
