CARE AND MAINTENANCE
STEAM BOILERS
CAUTION:
• The boiler area should be kept free of combustible materials, gasoline and other flammable liquids.
• The boiler and venting system must be kept free of obstructions of the air louvers and draft hood
relief openings.
• The following procedures must be conducted as outlined to assure safe operation of the boiler.
• All cover plates, enclosures, and guards must be in place at all times except during maintenance
and servicing.
3.1 REQUIRED PRECAUTIONS DURING TEMPORARY USE
GENERAL
A boiler is often utilized in new construction to
assist in curing of building components or to
provide temporary heat for the construction crew
or for other purposes during the time the building
is under construction. If precautions are not taken
during this time to protect the boiler, a great deal
of damage can occur before the ultimate owner
takes over the building.
It is the mutual responsibility of the installing
contractor and the boiler owner to consider the
effect of temporary usage on the boiler warranty.
The following should be observed so as to assure
the longevity of the boiler.
OPERATOR SKILLS/RESPONSIBILITIES
During the temporary use period, a single
individual must be assigned responsibility for the
care and operation of the boiler. This person's
responsibility must include, but not be limited to,
the following:
1. Knowledge of burner/boiler operation.
2. Possession and understanding of boiler/burner
operating instruction manual.
3. Assurance that the boiler is fed with only
treated water at all times and that chemical
treatment and blowdown procedures are always
followed.
4. Notification to the manufacturer (or
manufacturer's agent) to provide start-up services
if the boiler was purchased with start-up by a
factory representative.
5. Adherence to all of the start-up procedures
noted in the boiler/burner manual.
6. Considerations of warranty should the boiler be
used for temporary heat without adherence to the
recommended start-up and operating procedures
outlined in the instruction manuals.
3.2 CLEANING THE BOILER AND SYSTEM - NEW SYSTEMS
BOIL OUT PROCEDURE
The internal surfaces of a newly installed boiler
will have oil, grease or other protective coatings
used in manufacturing. Such coatings must be
removed since these coatings lower the heat
transfer rate and could lead to overheating of a
tube and reduce operating efficiency. Before
boiling out procedures may begin, the burner
must be ready for firing. The operator must be
familiar with the procedure outlined in the
boiler/burner operating instruction manuals.
In combination with system contamination,
bacteria may cause objectionable odors,
sometimes resembling natural gas. It is important
to keep these fumes from air intakes which would
distribute them throughout the building. On steam
humidification systems this is especially critical.
Consult your local water treatment chemist for
further information.
