InstallatIon
In general
Congratulations on your new HWAM woodburning stove.We are pleased that you have chosen a HWAM
woodburning stove and condent that it will give you much pleasure.To ensure optimum operation and
safety, we recommend that the installation should be carried out by an authorised HWAM retailer or
a tter recommended by the retailer. For an overview of HWAM retailers, visit www.hwam.com under
“Retailer locations”.
Safety
The installation of your HWAM woodburning stove must always comply with all European, national and
local building regulations.The installation must be carried out in accordance with the instructions in the
installation and user manuals and subsequently registered with the local authorities. Upon installation,
the chimney sweep must approve the installation before you can start using the woodburning stove.All
HWAM woodburning stove packaging material must be handled in accordance with local waste manage-
ment regulations.
Room requirements
Always ensure a supply of fresh combustion air to the room where the stove is to be installed. The
woodburning stove uses approx. 8-24 m3 of air per hour.A window that can be opened or an adjustable
air valve will be sufcient. It must not be possible to block the adjustable air valve/grate. In newly built/
airtight dwellings, we recommend that a fresh air system should be installed for the direct supply of
external air to the combustion.This fresh-air system may be bought separately.
Before installing the stove, you must ensure that the load-bearing capacity of the oor can withstand the
weight of the stove and the chimney. The weight of the chimney should be calculated according to its
dimensions and height.

European, national and local regulations must be observed in terms of the size and thickness of a non-
combustible oor covering the oor in front of the combustion chamber opening. Ask your HWAM
retailer for assistance.The combustion chamber opening is 45,0 cm wide.

Remember to pay attention to the applicable regulations concerning the required distance
between the wall and smoke pipe.
Please be aware that not all glass parts are heat-resistant. For this reason, a glass wall should sometimes
be treated as a combustible wall, in which case we ask you to contact your local chimney sweep or glass
producer to hear at what distance the stove should be kept from glass.
Requirements for chimney and smoke pipe
The height of the chimney must ensure sufcient draught and prevent any smoke nuisance.As a general
rule, satisfactory draught conditions are achieved if the chimney is 4 m above the stove and at least 80
cm above the ridge. If the chimney is placed at side walls, the top of the chimney should always be higher
than the ridge or the tallest point of the roof.Always be aware of any national and/or local regulations
applying to thatched roofs and the location of the chimneys.r.
The woodburning stove requires a minimum draught of 12 Pa (measured at EN 13240 measurement
point). If measured just above the smoke ue socket, the chimney draught must be 18-20 Pa.
The chimney must have a minimum clearing of Ø 150 mm. The chimney must be provided with an
