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 sucient draught and prevent any smoke nuisance. As a
general rule, satisfactory draught conditions are achieved if the chimney is m above the stove
and at least 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 stove requires a draft of at least Pa.
The chimney must have a minimum clearing of Ø mm. The chimney must be provided with
an easily accessible cleaning door. The chimney and flue duct must be of flue class T 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.
