When the distance from the stove upper surface is at least1,200 mm, the ceiling does not require
protection.
2.4.2. 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 2.4.2.)
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 100 mm 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. If it stands with its back and both sides next to
brick wall, 100 mm should be left on both sides to ensure air circulation. At the back, 50 mm
remains sufficient.
The safety distances around a no insulated connection pipe can be reduced in a similar manner.
The pipe’s insulated part within the sauna must always extend to 400 mm below the ceiling.
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. 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. Connecting from the top
Make an opening into the brick chimney that is 2–3 cm larger than the connection pipe.
Use a 45° bent pipe for the connection from the top of the stove, which can be turned to align
with the chimney. Suitable 45° bent pipes are available at the hardware store. Extend the bent
pipe with an extension piece, if necessary. Install the stove’s own connection pipe in the door-
side flue opening on top of the stove (the other opening is the sweeping hole, which must not be
used for the pipe!). The bent pipe is then attached to the stove’s own connection pipe. Saw the
bent pipe and any extension pipe down to a suitable size where necessary. Make sure the pipe
extends sufficiently into the chimney (but not so far that it blocks up the chimney).
Seal the empty space between connection pipe and chimney with flexible, fireproof material such
as stone wool. The lead-through is then tidied up with a Kastor covering plate, which is available
at your hardware store. The covering plate is attached to the wall with metal bolts or fireproof
paste. See picture 2.5.2.
2.6. Connecting to a Kastor chimney
The Kastor stove can be connected from the top to a factory built Kastor chimney.
Make sure to choose the correct chimney type with regard to your stove model, chimney height,
temperature class T 600, exterior circumstances etc. For best results we recommend that you
install a chimney valve, as well. Picture 2.6.
