Open the casing door and ash door (7)
Clean the combustion chamber
Keep the primary air feeds (3) clean with
bellows for primary air feeds (19)
Keep the combustion plate inputs clean with
(5) clean with bellows for primary air feeds
(19)
Clean out the combustion tray and
combustion plate using the bellows for the
combustion plate (18)
Close the ash door (7).
Any elongation fissures on the
insulation plates or combustion
chamber bricks do not affect
their functioning and therefore
do not represent a claim
against the guarantee.
During cleaning ensure that the
slot between the burner plates
is not clogged (see picture
below). On the burner plates
themselves, an ash layer of
about 3cm can be left which is
provided for glow sustainment.
Note:
The combustion chamber must always be cleaned
last, as the ash may fall in the burn-off areas when
cleaning the heat exchanger pipes.
10.4
Cleaning the flue pipe
This should be cleaned at least once a month using
a chimney cleaning brush.
Note:
Remove the flue temperature sensor before
cleaning as it could be damaged.
10.5
Filling shaft – Filling shaft
door
The filling shaft walls are not heating surfaces and
must therefore not be cleaned. The deposit arising
on the filling shaft walls is a normal chemical
process and flakes off from time to time by itself or
can be removed using the bellows.
Note:
For perfect functioning oft he boiler the filling shaft
door must always be shut tightly.
The filling shaft door should be
tested for leaks once a year!
10.6
Checking the heat exchanger
In “hard water” areas in particular, there should be
checks on whether the heat exchanger is furred up
and has to be cleaned. Where faults are identified,
ongoing maintenance is offered, as this may mean
important safety checking for operation in closed
heating units (checking the heat exchanger can be
carried out by manually pressing the thermal flow
protection. There should be a free flow of water into
the heat exchanger).
10.7
Checking the water level for
the heating unit
Care should be taken that the required water level
or unit pressure (min. 1.5 bar in cold condition)
should be maintained in the heating unit. Regular
checks are required.
Too low a unit pressure may
lead to simmering noises or the
build up of steam bubbles in the
unit.
10.8
Keeping the boiler room clean
Items that are not required for the operation or
maintenance of the boiler unit should not be stored
in the boiler room. Cleanliness and tidiness enable
good access for service and maintenance and
reduce the risk of accidents.
For reasons of fire protection and according to the
valid regulations: Only designated and permitted.
