The chimney must have a minimum opening equivalent to Ø 150 mm. The chimney opening should always
be at least the size of the outlet socket of the stove. The chimney must have an easily accessible soot door.
Smoke pipe and chimney must always be suitable for a stove connection. Ask your HWAM dealer for
more information.
Fitting the loose parts
Before the stove is installed, you must ensure that all loose parts are fitted correctly.

1. Smoke shelf. Fits on top of side panels and should always be pushed right back against the back panel.
2. Baffle plate. Should always be fitted.
3. Cover plate. Should always cover the grate.
4. Ember/log guard. Place this inside the door.
5. Heat guard. Should always be in place.
6. Smoke shelf support. The front edge of the smoke shelf is protected by a U-shaped rail which should
always be in place (only Skamolex shelves).
7. In order to dismount the smoke shelf, it will first be necessary to dismount one side panel. Lift up
the smoke shelf and pull the edge of the side panel which is furthest away from you towards the
middle, until it freely passes smoke shelf support at front edge.
Connection to chimney
HWAM 7H has 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 brick chimney.

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.
