Troubleshooting

Log Set is Smoking / Sooting Excessively

It is natural and unavoidable for vented gas log sets to produce moderate levels of carbon (soot) where flame contacts the logs. The logs can be cleaned using a soft-bristle brush. However, if soot is pro- duced where there is no flame impingement, one of the following may be the cause:

Fireplace venting system not drafting properly: Make sure the damper is wide open at all times. Preheat the flue in very cold weather by burning the log set at a very low level, then slowly increasing the flame height over a matter of hours. Have the fireplace and the venting system professionally cleaned.

Excessive flame impingement or blockage: Make sure there is proper spacing between the logs so they are not smothering the flame. Rearrange the logs so they are touched less by the flames.

Excessive gas supply/pressure: Make sure the gas pressure coming into the fireplace does not exceed the maximum pressure allowed with this gas set (refer to Tables on page 4). If you are using the gas logs with a safety pilot kit, make sure you installed the correct orifice into the set.

Burner is Excessively Noisy

Please Note: The movement and combustion of gas will create low, unavoidable levels of noise.

Excessive gas pressure: Make sure the gas pressure coming into the fireplace does not exceed the maximum pressure allowed with this gas log set (refer to Table on Page 3). If you are using the gas logs with a safety pilot kit, make sure you installed the correct orifice into the set.

Passage of air/gas across irregular surfaces: There may be burrs, paint or other blockages on the burner bar ports. Check these ports and remove any blockage.

Gas Connector: Relieve any tight bends or kinks in the flexible gas connector. Switch to a smooth aluminum gas connect, which can be purchased at any hardware or home improvement store.

Burner Flame is Too High (8-12” Above Top Logs) or Too Low (Below Top Logs)

Incorrect gas supply, pressure or burner orifice used: Make sure the gas pressure coming into the fireplace falls between the minimum and maximum pressures allowed with this gas set (refer to Table on Page 3). If you are using the gas logs with a safety pilot kit, make sure you installed the correct orifice into the set.

Blocked ports (low flame only): Free the main burner orifice and burner bar ports of any burrs, paint or other blockage.
