Chapter 5 — Service And Periodic Maintenance
5-6 Part No. 750-295
If any adverse conditions are observed during operation or
inspection, contact your authorized Cleaver-Brooks service
representative.
When inspection and servicing are completed, reassemble the
burner in reverse order. When re-fastening burner door:
1) Coat bolt threads with anti-seize compound.
2) Tighten bolts gradually in a diagonal pattern to ensure a secure
fit (see Figure 5-5 ). It may take several cycles of the pattern to
reach uniform tightness.
3) Torque bolts to 11 ft-lbs (132 in-lbs).*
Ensure that all connections are tight and secure before
reconnecting power or fuel supply. After turning the gas supply
on, reset the gas pressure switches.
5.5-IGNITION ELECTRODES
The ignition electrodes should be checked on an annual basis or as needed if ignition problems are
encountered. Replacement should be accomplished as shown in
Figure 5-6 with the electrode turned
toward the burner mantle/canister after it is inserted into the burner head.
NOTE: A gas valve leak test is recommended during fireside
inspection.
*NOTE: Re-torque door bolts 7-10 days after replacing burner door
gasket.
