TROUBLESHOOTING
Note: All troubleshooting items are listed in order of operation.
WARNING: Turn off log set and let cool before
servicing. Only a qualified service person should
service and repair log set.
OBSERVED PROBLEM
Log set is smoking/sooting excessively
( Note: It is natural and unavoidable for
vented gas log sets to produce moderate
levels of carbon (soot) where flames
contact the logs. This is especially true
with propane/LP gas.)
Burner is excessively noisy
( Note: The movement and combustion of
gas will create low, unavoidable levels of
noise.)
Burner flame is too low or too high
White powder residue forming within burner
box or on adjacent walls or furniture
POSSIBLE CAUSE
1. Poor fuel quality
2. Fireplace venting system not drafting
properly
3. Excessive flame impingement or
blockage
4. Improper fuel/air mixture
5. Excessive gas supply/pressure
1. Passage of air/gas across irregular
surfaces
1. Incorrect gas supply or pressure
2. Blocked burner orifice or burner mani-
fold ports
3. Improper burner orifice size
1. When heated vapors from furniture pol-
ish, wax, carpet cleaners, etc. may turn
into white powder residue
REMEDY
1. Contact local natural or propane/LP gas
company
2. Adjust damper wide open and/or have
fireplace and venting professionally
cleaned and checked
3. Separate the logs to allow more flame
passage
4. Remove any foreign items from the
flame pattern and/or check for proper
orifice sizing
5. Preheat flue in very cold weather
1. Relieve any tight bends or kinks in gas
supply line
1. Check for proper gas supply pressure
2. Free burner orifice and manifold ports
of any burrs, paint, or other blockage
3. Verify proper burner orifice sizing (see
Figure 2, page 4)
1. Turn heater off when using furniture
polish, wax, carpet cleaners or similar
products
