Vertical cross-section of smoke flue (Drawing B):
1. Steel chimney.
2. Knee pipe. Fits into the smoke flue socket.
3. Jamb of the brick-built chimney.
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 ducts of the HWAM stove.
8. Cover for back outlet / hotplate for top outlet.
9. Insulation. 25 mm thickness.
10. Inside cover.
11. Fitting bolt.
12. Smoke flue regulating damper.
13. Soot door.
14. Smoke flue for back outlet (remove cover and insulation).
When the stove is connected at the top, the back outlet is shut off with an ins ulation disc and a
cover plate which is bolted to an inside cover plate. No insulation is necessary if the stove adjoins a
non-flammable wall. We recommend that the stove is connected to a top outlet in order to achieve
the highest possible temperatures in the baking section.

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 limiting 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 efficiency, it is important to have the right chimney draft, min.12 Pa.
