TEST SOLUTION
- Check if pilot can be lit by a match.
- Check that the wire is connected to the push button
igniter.
- Check if the push button igniter needs tightening.
- Replace the wire if the wire insulation is broken or frayed.
-
Replace the electrode if the ceramic insulator is cracked
or broken.
- Replace the push button ignitor
- Fill the tank.
- Spark gap should be 0.150" (3.8mm) to 0.175" (4.5mm)
from the electrode tip and the pilot burner. To ensure
proper electrode location, tighten securing nut (fi nger
tight plus 1/4 turn).
- Check that the manual valve is turned on.

- 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 as described on the chart below.
with main burner is operating on 'HI'.
- Outlet pressure can be checked the same as above
using screw (B). Gauge should read as described on
the chart below. Check that main burner is operating on
'HI'.
