Floor plate
European, national and local regulations must be observed in terms of the size and thickness of a non-
combustible floor covering the floor in front of the combustion chamber opening. Ask your HWAM
retailer for assistance. The combustion chamber opening is 56.0 cm wide.
Distance to combustible materials
Please refer to local building regulations to determine the size of the fireproof area in front of the fireplace.
The insert must be positioned at least 30 cm above the floor if the floor is made of combustible material.
If there is combustible material around the outer casing, non-combustible insulation (Fire Batts) is required
between the casing and the combustible material. The insulation must be 80 mm thick on both sides of
the casing, 120 mm behind the casing and 60 mm thick beneath the bottom of the casing. The requirement
for insulation above the top of the casing is 150 mm. The thermal conductivity of the insulation must be
less than 0.1 W/m x K (as measured at 200 ºC).
Requirements for chimney and smoke pipe
The height of the chimney must ensure sufficient 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.
The woodburning stove requires a minimum draught of 12 Pa (measured at EN 13240 measurement
point). If measured just above the smoke flue 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 eas-
ily accessible cleaning door. The chimney and flue duct must be of flue class T400 and be CE marked.
Furthermore, it must have obtained the classification of G in soot fire testing. The required distance
to combustible material must be complied with in accordance with the brand label. Ask your HWAM
retailer for further information.
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.
The chimney draft is created by the differences in temperature inside and outside the chimney. The higher
the temperature within the chimney, the greater the draft. It is crucial, therefore, that the chimney is warmed
up properly before closing the damper and limiting the combustion in the stove (a brick chimney takes
longer to warm up than a steel chimney). On days where the weather and wind conditions create insufficient
draught inside the chimney, it is even more important to warm up the chimney as quickly as possible. The
trick is to quickly get some flames going. Split the wood into extra fine pieces, use an extra firelighter, etc.
If the stove has not been used for a longer period, it is important to check that the chimney pipe is not blocked.
