Part 13 - Maintenance
A. Procedures
Periodic maintenance should be performed once a year by a
qualified service technician to assure that all the equipment
is operating safely and efficiently. The owner should make
necessary arrangements with a qualified heating contractor
for periodic maintenance of the boiler. The installer must also
inform the owner that a lack of proper care and maintenance of
the boiler may result in a hazardous condition.
BEFORE EACH HEATING SEASON a trained and qualified
service technician should perform the inspections as per the
boiler inspection and maintenance schedule in this manual.
Failure to do so could result in death or serious injury.
The combustion chamber insulation 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 a 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 job
site conditions. Current NIOSH recommendations can
be found on the NIOSH website: http://www.cdc.gov/
niosh/homepage.html. NIOSH
manufacturers, and phone numbers are also listed on this
website.
• Wear long-sleeved, loose fitting clothing, gloves, and eye
protection.
• Apply enough water to the combustion chamber lining to
prevent dust.
• Wash potentially contaminated clothes separately from
other clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
• Eye: Irrigate immediately.
• Breathing: Fresh air.
Do not use solvents to clean any of the burner components.
The components could be damaged, resulting in unreliable or
unsafe boiler operation, substantial property damage, severe
personal injury, or death.
B. Closing the Combustion Chamber Door
The boiler door can be opened to aid in mounting the burner and
other combustion components, and to clean the combustion
chamber. It should be closed with the proper torque before
starting the boiler.
NOTE: Whenever opening or closing the combustion chamber
door, (ensure you have personal protective equipment (PPE) in
place. Wear an N95 certified dust respirator, eye protection, and
gloves.

The recommended torque for closing the door should be
between 14 and 22 ft/lb. Use an appropriate torque wrench to
control that value. Otherwise use the standard door handle
(whose length is 220 mm) with a force between 66 and 100
ft/lb.
Tighten the hinges in a pattern (top left, bottom right, top
right, bottom left) to ensure a proper seal.
