3. Remove cast grate 6 (Figure 7d).
4. On the floor plate, clean the area underneath
the grate with a vacuum cleaner. It is important
to ensure that the two air inlets in the floor plate
between the wind box 7 (Figure 7) and the grate
are clean.
If no vacuum cleaner is available: pull the front
cladding 8 forward (Figure 7e).
Unscrew cover 9 on the wind box. Thoroughly
clean both air inlets 10 with the round brush 11
(Figure 7f). Wipe any residues through the com-
bustion chamber cone (see pos. 9, page 7) into
the combustion chamber. Reinstall the grate and
mount the wind box cover and the front cladding
(slots on top).
Cleaning the heating boiler
Annual maintenance by a heating engineer
(or more often, if required)
See chapter “Maintenance” in the “Technical infor-
mation/Installation instructions”.
Please note!
It is essential to clean the entire boiler thor-
oughly at the end of the heating season.
Insufficient cleaning does not only lead to
increased fuel consumption, but also short-
ens the useful life of the boiler.
Note:
Small tension cracks in the refractory do not
affect the correct functioning of the boiler. They
are the result of stresses caused by temperature
changes.
The boiler should be thoroughly cleaned in accord-
ance with the applicable country-specific regulat-
ions - and
no less than 1 x per year
- by a heating
engineer (chimney sweep, installer, Hoval Customer
Service).
