8.2 BENCHMARK 750-5000N 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 12 Month Maintenance Kit P/N 58025-01 and all BMK750 – 5000N 24
Month 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:
Note that during installation, use the number of indexing (clocking) washers necessary that,
when tight, the gas injection tube is positioned as shown in Figure 8-1d.
