TROUBLESHOOTING

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
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 flames are too low or too high
WARNING: If you smell gas
• Shut off gas supply.
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the fire department.
OBSERVED PROBLEM
