Head Coil Defective; Incorrect Air Shutter Setting - Travis Industries Spirit 300 GS Service Manual

2 - 8

Head Coil Defective

If the thermopile production is adequate (see "Thermopile Defective") and the burner does not turn
on when jumped(see step #1 under "Burner Electrical Circuit is Faulty"), yet the burner does not turn
on, the Head Coil inside the gas control valve is malfunctioning.
Remedy
Replace the gas control valve.

Incorrect Air Shutter Setting

The air shutter regulates the amount of air allowed into the mixing tube prior to ignition on the burner.
It is factory-adjusted for use near sea level. But due to venting configuration, gas quality, and altitude,
the air shutter should be adjusted for each installation. The flames should be blue at the base and
orange/yellow at the top with no sooting. When adjusted correctly, the flames will be efficient and
attractive.
1 Start the heater, and let it burn for 15 minutes.
2 Inspect the flames.
Locate the air shutter adjustment
lever behind the gas control valve.
Move it up or down until the flame
is correct. Pushing up gives the
flame more air (making it bluer).
Pulling it down cuts air down,
making it more orange.
NOTE: If the air control is all the
way up, yet the flames remain
sooty, shut off gas to the fireplace
and contact a qualified gas service
technician.
Correct
Flames should be blue at the
base, yellow-orange on the top.
NOTE: The logs must be installed correctly to monitor the flame while adjusting the air shutter.
Locate the air shutter adjustment lever behind the gas control valve.
NOTE: If the air control is all the way up, yet the flames remain sooty, make sure to check the
restrictor position (on DVÕs only), gas inlet pressure, and log position.
Remedy
Move the air shutter lever up or down until the flame is correct. Pushing up gives the flame more air
(making it bluer). Pulling it down cuts air down, making it more orange.
