PROBLEM
Sulphur from fuel is being
deposited on glass, logs or
combustion chamber
surfaces.
Door is ajar.
Venting action is too great.
Blockage in vent.
Compromised venting.
GLASS EMBERS ONLY:
Too many glass embers.
Vent recirculation.
TEST SOLUTION
- Clean the glass, see "CARE OF GLASS" section
- DO NOT CLEAN GLASS WHEN HOT.
- If deposits are not cleaned off regularly, the glass
may become permanently marked.
- Tighten door clamps.
- Restrict vent exit with restrictor plate. See
"RESTRICTING VENTS" section.
- Remove blockage. In really cold conditions, ice
buildup may occur on the terminal and should be
removed. 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.
- Check venting system parameters (seal, length,
rise, etc.).
- Re-distribute glass embers so that only a single
layer is over top of the burner tube.
- Check joint seals and installation.
