Chapter 5. – Installation Check
WARNING
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.
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!
CAUTION
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 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 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.
