Notes:
Table 30 - Installation Checklist
Allowing the boiler 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 boiler failure, property
damage, personal injury, or death. Such product failures ARE NOT
covered under warranty.
In unusually dirty or dusty conditions, care must be taken to keep
boiler cabinet door in place at all times. Failure to do so VOIDS the
warranty.
The boiler 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 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.
Installer must also inform the owner that the lack of proper care and
maintenance of the boiler may result in a hazardous condition.
