PART 8. MAINTENANCE
A. MAINTENANCE PROCEDURES
All high efficiency condensing appliances will require more regular maintenance (cleaning) than their non-
condensing counterparts. Failure to do so may result in damage to the appliance that is not covered under warranty.
Failure to follow all of the instructions contained in this manual may also cause premature product failure that
may not be covered under warranty.
Periodic maintenance should be performed at least once a year by a qualified service technician to ensure that
all the equipment is in safe, efficient operation.
Failure to do so may eliminate warranty coverage
. In the first
year of operation, it is highly recommended that inspections of all connection points and the combustion chamber
be done at three month intervals, any signs of fouling or leaks must be thoroughly investigated immediately as
failure to do so may void warranty. Assuming no cause for excessive fouling is found, then the period of months
from initial start up that it was found that cleaning was required, shall become the required future minimum clean-
ing interval, but at no time should it exceed 12 months. The owner MUST make necessary arrangements with
a qualified heating contractor for proper 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 and lack of warranty
coverage. The installer should discuss the contents of the User’s Information Manual with the owner.
