WARNING
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
(Group1). 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
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 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.

flame sensing electrodes
• check the condition of the burner and its connection to
the aluminum front plate
• check for dirt in the combustion chamber, clean if
necessary. Use the vacuum cleaner for this cleaning
operation
• check the gas valve is calibrated correctly
• check that there is no dirt in condensate trap
• check the central heating system pressure
• check the expansion tank pressure
• check the vent system, clean if necessary
