Inspections and maintenance
- Remove the bottom panel with the furnace door open,
pulling it by the top part to release it from the blockage
system.
Extract the two ash pans and empty them. To extract the
pans, turn the front pins until they release from the blockage
system.
- IMPORTANT! STILE 27 is equipped with an internal heat
exchanger unit cleaning system which is controlled by
repeatedly pushing the lever in the inner top part of the
pellet combustion chamber.
This operation must be repeated until it slides without any
resistance.
Cleaning the surface of the heat exchanger pipes
guarantees the most efficient thermal exchange possible.
- It could also be necessary to clean the glass as it inevitably
gets dirty.
The frequency of this cleaning depends on use and the
quality of the pellets.
Clean the glass when it is completely cooled off, using
specific nonabrasive cleansers.
When cleaning is finished, put all pieces back in place
acting in the opposite order.
The frequency with which the glass is cleaned is
linked to how much the heat stove is used.
Boiler body maintenance
Danger!
Before performing any maintenance, make
sure the heat stove and its components
have cooled down.
Warnings
Never drain water from the system, even partially, unless
absolutely necessary.
Periodically check the proper operation and integrity of the
flue gas exhaust pipe and/or device.
If work or maintenance is performed on the structures near
the flue gas pipes and/or flue gas exhaust devices and their
accessories, switch the appliance off and, when the work is
over, check their efficiency.
Do not clean the heat stove and/or its parts with easily
flammable substances (e.g. petrol, alcohol, etc.).
Do not leave flammable substances in the room where the
heat stove is installed.
Do not clean the boiler room while the heat stove is running.
At the end of each heating period, inspect the heat stove to
keep the system in perfect efficiency.
Thorough maintenance always enhances energy saving and
safety.
IMPORTANT
Use brushes and a vacuum cleaner to clean
the heat stove; if rags are used, make sure they
are all recovered.
CLEANING AND ROUTINE MAINTENANCE STILE 27
STILE 27 must receive regular maintenance to guarantee its
correct and efficient operation.
The following cleaning operations must be performed only
when the heat stove is completely cold and disconnected
from the household electric mains.
Daily
-
Remove the ashes from the combustion chamber using a
vacuum cleaner intended for recovery of combustion
products.
-
This operation will be easier by removing the crucible from
the combustion chamber, as shown in the following figure.
Check the integrity of the bottom grate of the crucible and
in case of doubt, have it replaced.
Eliminate incrustations which obstruct the air passage
vents.
Remove any slag deposited around the crucible support.
