Chimney
The chimney is the "motor" of the insert and it is crucial for the functioning of the woodburning insert .
The chimney draft provides a partial vacuum in the insert . This vacuum removes the smoke from the
insert, 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 better the draft . It is crucial, therefore, that the chimney
is warmed through properly before closing the damper and limiting the combustion in the insert (a brick
chimney takes longer to warm through 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 . Contact your local chimney sweeper for the approval of your chimney .
Even a good chimney can function badly if it is not used correctly . Similarly, a bad chimney may function
well if it is 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's height makes
cleaning from above impossible, a cleaning hatch must be installed in the chimney .
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 .

The HWAM I 30/55s consists of a moveable, external brickwork casing, as well as an insert that is pushed
into place and connected once the brickwork casing has been assembled .
The HWAM I 30/55s can be connected in two ways:
1 . Mounting and connecting in an existing fireplace .
2 . New construction around the insert, possibly including heat ducts to other rooms .
1. Mounting and connecting in an existing fireplace (Drawing A1-A3).
Before mounting the insert in a brick-built fireplace, the regulating damper in the existing chimney must
be removed and the smoke neck, if any, should be widened so that the fire tube from the insert can be
connected directly to the chimney . Any bricks positioned on edge at the bottom of the fireplace should
also be removed .
In advance, decide with a specialist or the chimney sweep where a soot door (1) should be placed, so
that the fire tube can be cleaned from above while the door of the insert remains closed .
