MAINTENANCE REPORT
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 WARRANTY!
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.
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.

leakage. Continual fresh make-up water will reduce
boiler life. Leaking pipes could cause property
damage. Make sure all piping is properly supported.
Vent Check condition of all vent pipes and joints. Ensure all
vent piping is properly supported. Check for
obstructions at intake and exhaust termination points.
Gas Check Gas piping, test for leaks and signs of aging.
Make sure all pipes are properly supported.
