The PH20-30A is designed so that the igniter should
never have to be replaced. If for some reason the
igniter is broken or the burner head requires cleaning
and the igniter is removed, the igniter gap should be
checked. Set the gap to .125” +.03 -00. It is important
that the gap be set correctly for flame ignition and
flame sensing.
To set the spark gap:
1. bend the center electrode
slightly
2. check with feeler gage
between igniter tip and
center electrode
NOTE: igniter should not need
to be bent. Adjust center
electrode only
