7.2 IGNITER-INJECTOR
The ignitor-injector should be
inspected
annually and
replaced
at least every 24 months of
operation, sooner if there is evidence of substantial erosion or carbon build-up. Parts and
instructions are included in the CEN2000 12 Month (P/N
58025-25)
and 24 Month (P/N
58025-
26
and
58025-27
) Maintenance Kits.
The igniter-injector may be hot; therefore, care should be exercised to avoid burns. It is easier to
remove the igniter-injector from the unit after the unit has cooled to room temperature. To
inspect/replace the Igniter:
