• The smoke shelf (5). To be placed on top of the steel rail and on the holders in the sides.
• Two-piece smoke defector plate (6). Each half is hung on the hooks located beneath the top plate. The two
halves join in the holders behind the air pipe. Once the stove has been installed, twist the protection off
the two hooks by using pliers or a screwdriver.
• Cover plate (7). Should always cover the grate.
• Removable rear plate (2), covering automatic controls. This must always be mounted if the stove is
placed next to a combustible wall.
• Loose heat shield (8) under the ash pan. This can be used as a lid when the ash pan is removed for
emptying.
Cover plate (Drawing D)
Your HWAM woodburning stove is supplied with a loose cover plate for the shaking grate. This is a 3
mm thick iron plate. It is placed on top of the shaking grate and prevents the embers from falling into
the ash pan. The cover plate is raised approx. 8 mm above the grate, thus ensuring that the automatically
controlled primary combustion air is distributed evenly at the base of the combustion chamber.
Chimney
The chimney is the “engine” of the stove and it is crucial for the functioning of the woodburning stove.
The chimney draft provides a partial vacuum in the stove. This vacuum removes the smoke from the stove,
sucks air through the dampers for the so-called glass pane rinse which keeps the glass free of soot, and
sucks in air through both primary and secondary dampers for the combustion.
The chimney draft is created by the differences in temperature inside and outside the chimney. The higher the
temperature within the chimney, the greater the draft. It is crucial, therefore, that the chimney is warmed up
properly before closing the damper and limiting the combustion in the stove (a brick chimney takes longer to
warm up than a steel chimney). On days where the weather and wind conditions create insufficient draught
inside the chimney, it is even more important to warm up the chimney as quickly as possible. The trick is to
quickly get some flames going. Split the wood into extra fine pieces, use an extra firelighter, etc.
If the stove has not been used for a longer period, it is important to check that the chimney pipe is not
blocked.
It is possible to connect several devices to the same chimney. However, it is important to first check the
applicable rules.
Even a good chimney can function badly if it is not used correctly. Similarly, a bad chimney may function
well if used correctly.
Chimney sweeping
To prevent the risk of chimney fires, the chimney must be cleaned every year. The flue duct and the smoke
chamber above the baffle plate must be cleaned together with the chimney. If the chimney is too tall to
be cleaned from above, it must be equipped with a soot door.
In case of a chimney fire, close all dampers and call the firefighters. Before any further use, have the
chimney checked by the chimney sweeper.
