5.4. Adding fuel
Apart from using suitable fuel and sufficient chimney draft,
the stove operation has a major effect on keeping the view
window clean. In this context we recommend charging fuel
in only one layer, preferably using large (approx. 33 cm),
wood billets largely filling the firebox width.
Note! Additional fuel should only be placed on the basic
embers (no flame remaining).
5.5.
Operating mode during the transition period
During the seasonal transition period or in the event of
higher outside temperatures it is possible that chimney draft
problems occur under certain conditions during a sudden
increase in temperature, so that the exhaust gases are not
fully extracted.
5.6. De-ashing
After extended combustion, at least once per day, discharge
the ash through the riddling grate into the ash pan and empty
the ash pan. This is best done in the morning after embers
heating overnight with the stove in a relatively cold state.
Please ensure that the ash pan is emptied when
approximately half full so that the ash cone does not grow
up too closely to the grate. If the grate is packed into the ash
cone there is a risk for it to get damaged through
overheating since no cooling air can get to it.
Caution:
Prior to de-ashing always check if no residual embers are
present in the ash. Even if the ash is cold it may still contain
traces of embers that could lead to a fire in the waste bin.
Wood ash can be used as fertiliser.
5.7.
Emission limitation
The wood stove has been built for the combustion of low-
smoke fuels.
According to the Federal Emission Protection Act the
following must not be combusted for instance:
Moist wood or wood treated with wood protection
agent,
Fine wood chips,
Paper and cardboard (except for lighting),
Barks or chipboard waste,
Plastic or other waste.
Burning such materials will not only harm the environment
but also shorten the service life of your wood stove and the
chimney may also be damaged. Regular cleaning and care of
your stove also reduces pollutant emission. Obviously bark
adhering to wood billets can be burnt.
5.8.
Cleaning and care
At least once per year, if required more frequently, clean
and service your wood stove n the cold condition. To do so,
remove the ash deposits in the flue pipe and the smoke
baffle plates or draft baffle plates. Draft baffle plates made
of ceramic fibre or vermiculite can be removed for cleaning
(see Equipment Sheet). Please reinstall carefully in the same
position after cleaning. For cleaning the flue gas drafts an
ash extractor with fine particle filter is highly suitable. Dirt
on the view windowpane is best and most environmentally
friendly removed using a scouring pad moistened with water
and dipped into wood ash or other commercially available
domestic glass cleaners.
The chimney must also be regularly cleaned by the chimney
sweep. The required intervals can be enquired from your
responsible master chimney sweep.
The wood stove should be checked annually by a specialist.
