INTRODUCTION
All high efciency 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 qualied service technician to ensure that all the equipment
is in safe, efcient operation. Failure to do so may eliminate warranty coverage. In the rst 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 cleaning interval, but at no time should it exceed 12 months. The owner
MUST make necessary arrangements with a qualied 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.
An inspection should cover, at a minimum, the following areas:
