FIRED WATER BOILER
— Boiler Manual
Part number 550-101-233/0903 29
Annual startup
The boiler should be inspected and started annually, at the beginning of the heating season, only by a
qualified service technician. In addition, the maintenance and care of the boiler designated in Table 5
and explained on the following pages must be performed to assure maximum boiler efficiency and
reliability. Failure to service and maintain the boiler and system could result in equipment failure.
Electrical shock hazard — Turn off power to the boiler before any service operation on the boiler except
as noted otherwise in this instruction manual. Failure to turn off electrical power could result in
electrical shock, causing severe personal injury or death.
Address reported problems
1. Inspect any problems reported by owner and correct
before proceeding.
Inspect boiler area
1. Verify that boiler area is free of any combustible
materials, gasoline and other flammable vapors and
liquids.
2. Verify that air intake area is free of any of the
contaminants listed on page 8 of this manual. If any
of these are present in the boiler intake air vicinity,
they must be removed. If they cannot be removed,
reinstall the air and vent lines per this manual and the
Ultra Boiler Vent Supplement.
REMOVAL OF COMBUSTION CHAMBER LINING
The combustion chamber lining in this product contains ceramic fiber material. Ceramic fibers can be
converted to cristobalite in very high temperature applications. The International Agency for Research
on Cancer (IARC) has concluded, "Crystalline silica inhaled in the form of quartz or cristobalite from
occupational sources is carcinogenic to humans (Group 1).":
■ Avoid breathing dust and contact with skin and eyes.
• Use NIOSH certified dust respirator (N95). This type of respirator is based on the OSHA requirements for
cristobalite at the time this document was written. Other types of respirators may be needed depending on
the job site conditions. Current NIOSH recommendations can be found on the NIOSH web site at http://
www.cdc.gov/niosh/homepage.html. NIOSH approved respirators, manufacturers, and phone numbers
are also listed on this web site.
• Wear long-sleeved, loose fitting clothing, gloves, and eye protection.
■ Apply enough water to the combustion chamber lining or base insulation to prevent airborne dust.
■ Remove combustion chamber lining or base insulation from the boiler and place it in a plastic bag for disposal.
■ Wash potentially contaminated clothes separately from other clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
■ Eye: Irrigate immediately
■ Breathing: Fresh air.
Inspect boiler interior
1. Remove jacket front door and inspect interior of
boiler.
2. Remove the venturi air inlet silencer and clean if
necessary. Replace silencer.
3. Vacuum any sediment from the inside of the boiler
and components. Remove any obstructions.
Do not use solvents to clean any of the
boiler components. The components could
be damaged, resulting in unreliable or
unsafe operation.
