The tip of the igniter is exposed to a harsh environment
consisting of high temperatures and combustion products.
Periodic servicing is required.
MAINTENANCE
1.
Using a small wire brush, reach into the outlet of the
heater and brush the igniter electrode. Ensure any
buildup is removed.
2.
Test the igniter. With the gas supply shut off, turn the
heater on. If there is not a spark, or a weak spark is
evident, either check the gap of the igniter electrode
or replace the igniter. If a spark jumps between the
electrodes, the igniter is functioning properly.
REPLACEMENT
1.
Remove ignition cable from igniter. See Fig. 11.
