OM-BPM-15/30/40E(C,A,C2T™) & BPP-30/40E(C,A,C2T™)
perform the work.
Service personnel should check the unit at least once a year. This periodic
maintenance should include inspecting electrical wires and connections, cleaning
the inside of the control console, and possible adjustment of the pilot light. (Units
with standing pilot ignition only) At least twice a year, grease the two trunnion
bearings and worm gear.
We recommend the use of number two grade LGI lithium grease. Add grease
through the zerk fittings on the gear hosing until grease flows out of the bearings
around trunnion shaft. Also, add grease in the gear to cover arc that is in contact
with the worm gear. Clean up excess grease.
A Service Log is provided with the warranty information at the back of this manual.
