General information
Installation of your HWAM woodburning stove must always comply with local building regulations. It is
a good idea to consult your local chimney sweep before installing, since he will be the one to sweep the
chimney and stove.
Always follow the instructions of the manual carefully and make sure that the installation is carried out
by a qualified professional.
HWAM packaging material should always be handled in accordance with the local rules for waste handling.
Room requirements
There must be a constant supply of fresh air to the room in which the stove is to be installed. A window that
opens or an adjustable air vent should be sufficient, but it is also possible to connect the stove to a HWAM
combustion air system. The air inlet/grating must be placed so that they do not become blocked.
Load-bearing capacity of floor
Before installing the stove, you must ensure that the load-bearing capacity of the floor can withstand the weight
of the stove and the chimney. The weight of the chimney should be calculated according to its dimensions and
height.
