Safety distances for the insulated flue channel are between 50mm and 150mm with the stove's
safety distances being the essential factors here.
For stone walls, the stove's safety distance is 50mm from the stove's outer surfaces, but
preferably 100mm to ensure sufficient air circulation.
The stove's safety distance to flammable material is 250mm to the side, at the back 500mm from
the stove’s outer surfaces. A safety distance of 1000mm should be left for in front of the stove
due to heat radiation and to allow room for work and maintenance. The absolute minimum is
500mm, but then you must ensure that the nearest panel in front of the stove does not exceed a
temperature of 85
o
C during test heating.
When the distance from the stove upper surface is at least 1200mm, the ceiling does not require
protection.

Reduction of safety distances
The required safety distances at the back and sides can be reduced by 50% using a single layer
of protection and by 75% with a doubled layer. The protection can be either a 1 mm thick metal
sheet or 7 mm of fibre-reinforced cement board (not gypsum board coated with paper or similar).
(Picture 2.4.1.) Safety distance is measured from the stove to flammable material.
A ventilation space of 30 mm must be left between wall and protector. The protector must be
detached from floor and ceiling (likewise between the plates for doubled protectors). If the sauna
has a flammable floor in front of the stove, the area to be protected extends 250mm beyond the
door’s sides and a minimum of 400 mm in front of it. In this case, the protection must be at least
a 1 mm thick metal sheet.
If the stove is installed with one side and the back against a brick wall, safety distances of 50 mm
to the side and 50 mm at the back are sufficient. Recommendation 100mm to ensure air
circulation.
The safety distances around a non-insulated connection pipe can be reduced in a similar
manner. The flue pipe’s insulated part within the sauna must always extend to 400 mm below the
ceiling.
In the case of the insulated part of the pipe the stove's safety distances are the determining
factor, which means that they can be reduced with insulation according to Picture 2.4.2.
For chimneys, the minimum safety distances to flammable material differs from product to
product. Always check the manufacturer’s instructions. In case of doubt, approach your local fire
safety officials.
2.5. Connecting the stove to a brick chimney
The stove can be connected to a brick chimney from the top and from behind. For a brick
chimney connection, the safety distances and protectors named in chapter 2.4. and the
chimney’s masonry regulations must be adhered to.
2.5.1 Stoves Saga JK and KSIL with extended feed doors
Stoves with extended feed doors must only be installed into walls made of non-flammable
material (brick, concrete etc.).
The non-flammable material must be arranged around the door
extension as shown in picture 5. If there is a flammable floor in the room with the door, the area
