4 Settings and maintenance
Maintenance
The Swedish Rescue Services Act specifies how of -
ten a boiler is to be swept and at what intervals with
regard to the risk of soot fires. Sweeping carried out
by a chimney sweep includes all flue gas routes from
the hearth to the top of the chimney.
You can check the boiler’s fire-affected surfaces and
flue gas ducts yourself to determine how often the
boiler should be swept.
Gas, which contains tar substances, builds up in the
wood magazine. These substances condense on the
walls of the wood magazine and are later burned off.
This means that the walls of the wood magazine do
not usually have to be cleaned.
For optimum combustion and efficiency the boiler’s
secondary combustion chamber should be cleaned
after about 15 smoking (burning) cycles.
Tips and remarks
In order to ensure the safety of boiler maintenance
and cleaning activities, please observe the rules and
notes below:
• Maintenance and cleaning activities have to be
completed prior to commencement of boiler op-
eration, or when the combustion chamber is com-
pletely cool.
• During maintenance and cleaning always use
protective gloves, in order to avoid burning of
skin.
• When cleaning the boiler never use abrasive or
caustic cleaning agents.
• Clean the boiler regularly in order to maintain
its efficiency, safe operation and environmental -
ly-friendly combustion process.
• Clean ceramic inserts using brush only in order to
avoid damage to ceramics.
Cleaning the loading chamber
Cleaning the loading chamber::
1. Wait until the boiler cools down.
2. Open the loading chamber door.
3. Remove the smoke blocking plate as per the se-
quence in figure below (numbers 1, 2, 3).
4. Dismantle 6 lateral walls in the loading chamber,
as per the sequence in figure below (numbers 4,5).
5. Check the cleanness of the loading chamber and
clean, if necessary, using a scraper and a brush.
6. Swipe the removed residue out through the open-
ing in the ceramic plate.
7. Install lateral walls in the loading chamber.
8. The loading chamber was cleaned properly and
is ready for operation.
Boiler cleaning interval depends to a large
extent on quality of fuel. Maximum permitted
moisture content in fuel is 20%. Exceeding the
permitted moisture content shall have an ad-
verse impact on combustion parameters and
boiler lifecycle.
ATTENTION
Maintenance and cleaning activities have to
be completed prior to commencement of boiler
operation, or when the combustion chamber is
completely cool!
