CHAPTER 8
Inspection and Maintenance
8.1 — Overview
A well-planned maintenance program will help avoid unnecessary down-time or costly repairs, promote
safety, and aid boiler 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 of daily, weekly, monthly, semi-
annually, and yearly maintenance activities provides a valuable guide and aids in obtaining economical and
reliable service from Cleaver-Brooks equipment. A boiler inspection schedule is shown in Table 8-1. It is
important to realize that the frequency of inspection will depend on variable conditions: such as load, fuel,
system requirements, boiler environment (indoor/outdoor) etc.
Good housekeeping helps maintain a professional appearing boiler room. Only trained and authorized personnel
should be permitted to operate, adjust, or repair the boiler and its 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 semi-automatic in opera-
tion, the devices require systematic and periodic maintenance. Any automatic feature does not relieve the operator
from responsibility, but rather frees the operator from certain repetitive chores providing 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 and permit prompt corrective action that may prevent extensive repairs or unexpected
downtime. Any leaks — fuel, water, steam, exhaust gas — should be repaired promptly and under conditions that
observe 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.
Inspection and maintenance should be performed only by trained personnel who are familiar with this equipment. Fail-
ure to follow these instruction could result in equipment damage.
