Spark gap is incorrect.
-
Spark gap should be 0.150” to 0.175” (5/32” to 11/64”
approx.) from the electrode tip and the pilot burner. To
ensure proper electrode location, tighten securing nut
(
fi
nger tight plus 1/4 turn).

fi
ce for blockage.
-
Replace the valve.
-
Call the gas distributor.

too large or too small.
Carboning occurs.
Unit is over-
fi
red or under
fi
red.
-
Check pressure readings:
-
Inlet pressure can be checked by turning screw (A)
counter-clockwise 2 or 3 turns and then placing pressure
gauge tubing over the test point. Gauge should read
7” (minimum 4.5”) water column for natural gas or 13”
(minimum 11”) water column for propane. Check with
main burner is operating on ‘HI’.
-
Outlet pressure can be checked the same as above
using screw (B). Gauge should read 3.5” water column
for natural gas or 10” water column for propane. Check
that main burner is operating on ‘HI’.
-
AFTER TAKING PRESSURE READINGS, BE SURE TO
TURN SCREWS CLOCKWISE FIRMLY TO RESEAL.
DO NOT OVER TORQUE.

Check that the logs are correctly positioned.
-
Open air shutter to increase the primary air.
-
Check the input rate: check the manifold pressure and
ori
fi
ce size as speci
fi
ed by the rating plate values.
-
Check that the door gasketing is not broken or missing
and that the seal is tight.
-
Check that both vent liners are free of holes and well
sealed at all joints.
-
Check that minimum rise per foot has been adhered to
for any horizontal venting.
