Distance to combustible material
3.1.1.
Double wall Sauna system chimney DW50-M
This double wall chimney is tested non-enclosed and with insulated floor penetration. Chimney is installed leaving not less than 100 mm between
the outer surface of a chimney and combustible materials, if national legal acts do not indicate a bigger distance. When installing the chimney next
to combustible constructions (e.g. walls), ≥100 mm distance to combustible materials must always be maintained. A gap between the combustible
construction (e.g. wall) and chimney must be ventilated. In a case the chimney passes through combustible building constructions (e.g. floor, roof),
they must be equipped with holes of adequate size, which would allow to maintain a safe distance from a surface of the chimney to combustible
materials. When a thickness of building construction is not larger than 200 mm, a gap from the outer wall of the chimney to combustible materials
is fully filled with insulation materials indicated in Picture 3. If the thickness of combustible construction is from 200 mm to 500 mm, a gap of 200
mm height in the lower part of construction between the chimney and combustible materials is fully filled with insulation materials indicated in the
Picture 3, the rest part is filled with an insulation material indicated in Picture 3, but air gap of 50 mm must be left around the chimney.

Single wall Sauna connecting flue pipe SW-M
The elements of single wall Sauna connecting flue pipe system SW-M are used to connect a sauna stove to a chimney and mounted at the distance
not less than 500 mm to combustible materials, if national legal acts do not indicate a bigger distance.
3.2.
Joints
The joints of chimney elements in locations where it passes through the floor, roof or wall are not allowed.
Double wall chimney and connecting flue pipe elements shall be installed considering the flow direction of combustion products indicated on the
product marking stickers.
3.2.1.
Double wall Sauna system chimney DW50-M
Double wall chimney elements are connected to each other by means of spigot and socket joints which gives a depth of the insert joint of 50 mm.
Double wall chimney joints are secured by locking bands, which cover the joint. Please note that the locking band must be fitted properly on the
joint of the chimney sections (see Figure 4 ). Do not fit the locking band upside-down. Having fitted the locking band properly, tighten it using a hex
key (size no. 5).
