connection with a covered smoke outlet, nor the cleanout door and pipe connections. Please note that
bent and/or horizontal smoke pipes will reduce the effect of the chimney draft.

1. Smoke shelf. Must be placed on the steel rail and the holder at the front in the middle.
2. The baffle plate is suspended on three hooks beneath the top plate. One of the hooks has an additional
flap that is bent upwards as protection during transport. This flap should be removed with the help
of a screwdriver before installation.
4. The rear smoke outlet has been closed at the factory by screwing a plate over it and it is therefore
hidden behind the rear plate.
5a. Removable rear plate, covering automatic controls. This must always be mounted if the stove is placed
next to a combustible wall.
5b. Loose heat shield. This must always be mounted if the stove is placed next to a combustible wall.
6. Loose heat shield beneath the ash pan. Can be used as a lid when the ash pan is removed for emptying.
Connection to chimney
All the stoves have both rear and top smoke outlet that can be connected to an approved steel chimney on
top or directly out at the rear to a chimney.
Make sure that the chimney is tight and that no false draft is caused around neither the cover plate, in
connection with a covered smoke outlet, nor the cleanout door and pipe connections. Please note that
bent and/or horizontal smoke pipes will reduce the effect of the chimney draft.

1. Steel chimney.
2. Flue gas elbow. Fits into smoke flue socket.
3. Brick-built jamb of flue.
4. Built-in pipe sleeve. Fits smoke flue.
5. Wall rosette. Covers disruption to wall around pipe sleeve.
6. Joint. Sealed with packing material.
7. Smoke outlets of the HWAM stove.
8. Cover plate in the external rear plate – break off if a rear outlet is required.
9. Cover screwed in position: secure it to the top plate with screws if a rear outlet is required.
10. Smoke bushing: to be screwed to the back of the stove if a rear outlet is required.
11. Adjusting damper in smoke pipe.
12. Cleaning hatch.
13. Smoke pipe to rear outlet.
14. Loose cast iron cover: to be placed on the top plate when there is a rear outlet.
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
