to freezing.
NOTE
Failure to properly maintain the PB-1525 can result in equipment
damage.
The boiler/furnace needs to be cleaned on a regularly basis by a trained,
certified professional. During operation of the burner, fly ash is created.
This ash is carried throughout the boiler/furnace through the normal
combustion gas flow from the burn chamber, through the firebox, over
the heat exchanger surfaces and out the chimney. Fly ash will
accumulate on every horizontal surface within the boiler/furnace and will
also begin to adhere to the heat exchanger surfaces. This causes a
reduction in system efficiency due to the insulative effect the ash has
within the boiler/furnace. Regular cleanout of the boiler/furnace is
required to maintain the highest efficiency as well as to maintain proper
system operation.
It is recommended that the PB-1525 owner execute a regular
maintenance contract with your certified installation professional for
regular cleanout services on the boiler/furnace. In general, oil fired
boilers/furnaces require cleaning once per year when fired on oil; when
fired using a PB-1525 system cleanout may be required every 3-4 tons of
pellets burned, or more frequently depending on your particular boiler.
WARNING!
Failure to properly and regularly clean the boiler/furnace may
result in high chimney temperatures or system failure. Have the
boiler/furnace cleaned by a trained professional on a regular
basis.
Cleaning burner chamber
The PB-1525 burn chamber requires the regular, manual removal of clinker
and ash buildup. This task can be easily accomplished by the
homeowner in as little as one minute with practice.
Before beginning to clean the burn chamber, be sure the system is not
running by looking at the controller display and listening to the system. Do
not interrupt a burn cycle; rather, wait till the burn cycle is complete to
perform the cleanout.
