Operating the Boiler
Prevent Combustion Air Contamination
!
If the boiler combustion air inlet is located in any
area likely to cause contamination, or if products
which would contaminate the air cannot be
removed, you must have the combustion air and
vent repiped and terminated to another location.
Contaminated combustion air will damage the
boiler, and can result in severe personal injury,
death, or substantial property damage.
To prevent potential of severe personal injury or
death, check for products or areas listed in Table 1
before installing boiler. If any of these contaminants
are found:
• remove contaminants permanently.
— OR —
• isolate boiler and provide outside combustion air.
See national, provincial or local codes for further
information.

See the warnings and operating instructions on the
following pages to start and turn o the boiler. See
