A. GENERAl
While each boiler is tested for correct operation
before shipment from the factory, variable condi-
tions such as burning characteristics of the fuel
used and operating load conditions may require
further adjustment after installation to assure
maximum operating efficiency and economy. Prior
to placing the boiler into initial service, a complete
inspection should be made of all controls, connect-
ing piping, wiring, and aU fastenings such as nuts,
bolts and setscrews to be sure that no damage or
mis-adjustments occurred during shipment and in-
stallation.
safety and aids boiler code and local inspectors. An
inspection schedule with a listing of procedures
should be established. It is recommended that a
boiler room log or record be maintained, recording
daily, weekly and monthly and yearly maintenance
activities. This provides a valuable guide and aids
in obtaining economies and length of service from
Cleaver-Brooks equipment.
A well planned maintenance program avoids un-
necessary down time or costly repairs, promotes
Even though the boiler has electrical and mechan-
ical devices that make it automatic or semi-auto-
matic in operation, these devices require
systematic and periodic maintenance. Any "auto-
matic" features do not relieve the operator from
responsibility,
but rather free him of certain repeti-
tive chores, providing him time to devote to upkeep
and maintenance.
