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