Maintenance Report
In unusually dirty or dusty conditions, care must be taken to keep
water heater cabinet door in place at all times. Failure to do so
VOIDS WARRANTY!
Allowing the water heater to operate with a dirty combustion
chamber will hurt operation. Failure to clean the heat exchanger
as needed by the installation location could result in water heater
failure, property damage, personal injury, or death. Such product
failures ARE NOT covered under warranty.
The combustion chamber insulation in this product contains
ceramic ber material. Ceramic bers 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 certied 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
approved respirators, manufacturers, and phone numbers are
also listed on this website.
• Wear long-sleeved, loose tting 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.
The water heater requires minimal periodic maintenance under
normal conditions. However, in unusually dirty or dusty conditions,
periodic vacuuming of the cover to maintain visibility of the display
and indicators is recommended.
Periodic maintenance should be performed once a year by
a qualied installer / service technician to assure that all the
equipment is operating safely and eciently. The owner should
make necessary arrangements with a qualied heating contractor
for periodic maintenance of the water heater. Installer must also
inform the owner that the lack of proper care and maintenance of
the water heater may result in a hazardous condition.
