TROUBLESHOOTING
WARNING: Turn off log set and let cool before
servicing. Only a qualified service person should
service and repair log set.
POSSIBLE CAUSE
REMEDY
OBSERVED PROBLEM
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 mani-
fold ports
3. Improper burner orifice size
1. Battery is not installed. Battery power
is low
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
Remote does not function (GHRC only)
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
Adjusting Regulator Pressure For Pro-
pane/LP Conversion, page 7)
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. Replace 9-volt batteries in receiver and
remote control
