Inspection and Maintenance

A. GENERAL
A well-planned maintenance program will help to avoid
unnecessary downtime or costly repairs, promote safety, and
aid boiler inspectors in performing required periodic
inspections. An inspection schedule with a listing of
procedures should be established. It is recommended that a
boiler room log or record be maintained. Recording of daily,
weekly, monthly, and yearly maintenance activities provides
a valuable guide and aids in obtaining safe, economical and
lengthy service from your Cleaver-Brooks equipment. It is
important to realize that the frequency of inspection will
depend on variable conditions such as load, fuel, system
requirements, boiler environment, etc.
WARNING
! DANGER
Shut off electrical power to the boiler when
performing any service or maintenance
work or work that requires removal of
covers or component parts. Failure to heed
this warning could result in electrical shock,
serious personal injury or death.
Good housekeeping practices help maintain a professional
appearing boiler room. Only trained and authorized personnel
should be permitted to operate, adjust, or repair the boiler and
related equipment. The boiler room should be kept free of all
material and equipment not necessary to the operation of the
boiler or heating system.
Even though the boiler has electrical and mechanical devices
that make it automatic or semiautomatic in operation, the
devices require systematic and periodic maintenance. Any
"automatic" feature does not relieve the operator from
responsibility. Automatic features do free the operator of

certain repetitive chores, thus providing more time to devote
to upkeep and maintenance.
Alertness in recognizing an unusual noise, improper gauge
reading, leaks, etc., can make the operator aware of a
developing malfunction, permitting prompt corrective action
that may prevent extensive repairs or unexpected downtime.
Any leaks - fuel, water, steam combustion gases - should be
investigated and repaired with all due consideration of the
necessary safety precautions.
Preventive maintenance measures such as regularly checking
the tightness of connections, locknuts, setscrews, packing
glands, etc., should be included in regular maintenance
activities.
! DANGER WARNING
Inspection and maintenance should be
performed only by trained personnel who
are familiar with the equipment. Failure to
heed this warning could result in serious
personal injury or death.
B. PERIODIC INSPECTION
Insurance regulations or local codes may require a periodic
inspection of the pressure vessel by an authorized inspector.
Inspections are usually scheduled for periods of normal boiler
downtime such as during an off season. The major inspection
can often be used to accomplish maintenance, replacement,
or repair tasks that cannot easily be done at other times. This
also serves as a good basis for establishing a schedule for
annual, monthly, or other periodic maintenance programs.
While the inspection pertains primarily to the waterside and
fireside surfaces of the pressure vessel, it provides the
