WARNING: Turn off log set and let cool before servicing. Only a qualified service person should service
and repair log set.
Note: All troubleshooting items are listed in order of operation.
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 con-
tact 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
When ignitor button is pressed, there is no
spark at pilot

TROUBLESHOOTING
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 sur-
faces
2. Excessive gas pressure on natural gas
units
1. Incorrect gas supply or pressure
2. Blocked burner orifice or burner manifold
ports
3. Improper burner orifice size
1. Ignitor electrode not connected to ignitor
cable
2. Ignitor cable pinched or wet
3. Bad ground on piezo ignitor
4. Broken ignitor cable
5. Bad piezo ignitor
6. Ignitor electrode broken
7. Ignitor electrode positioned wrong

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
2. Check/reset gas regulator pressure
(see Figure 10, page 8)
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 5)
1. Reconnect ignitor cable
2. Free ignitor cable if pinched by any metal
or tubing. Keep ignitor cable dry
3. Scrape away paint on bracket for better
contact with ground on piezo ignitor
4. Replace ignitor cable
5. Replace piezo ignitor
6. Replace electrode
7. Reposition electrode
