Notes:
Table 28 - 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.
