wall to the uninsulated steel chimney.
Vertical cross-section of smoke fl ue (Drawing C):
11. Steel chimney
12. Knee pipe. Fits into the smoke fl ue socket.
13. Jamb of the brick-built chimney.
14. Built-in pipe sleeve. Fits smoke fl ue.
15. Wall rosette. Covers disruption to wall around pipe sleeve.
16. Joint. Sealed with packing material.
17. Smoke fl ues of the HWAM stove.
18. Cover for back outlet / hotplate for top outlet
19. Insulation. 25 mm thickness.
10. Inside cover.
11. Fitting bolt.
12. Smoke fl ue regulating damper.
13. Soot door.
14. Smoke fl ue for back outlet (remove cover and insulation).
When the stove is connected at the top, the back outlet is shut off with an insulation disc and
a cover plate which is bolted to an inside cover plate. No insulation is necessary if the stove
adjoins a non-fl ammable wall.
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.
Glove
A glove is delivered with your HWAM woodburning stove. This glove protects your hand when
operating the hot stove.
The importance of the chimney
The chimney is the “motor” 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 the 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 limit-
ing the combustion in the stove (a brick chimney takes longer to warm through than a steel
chimney).
Even a good chimney can function badly if it is not used correctly. Similarly, a bad chimney
may function well if it used correctly.
As HWAM stoves have a high effi ciency, it is important to have the right chimney draft, 10-
15 Pa.
