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 (16”) 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 and instructions for JK stoves
The KS stove can be connected to a brick chimney from the back or the top. JK 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.
2.5.0. Connection from the rear, only in KS models
Make an opening in the brick chimney that is 2-3cm (13/16” – 1 3/16”) wider than the connection
pipe.
Detach the stove's outer back mantle. Use a screwdriver to detach the plate covering the hole in
the inner back mantle. Move this covering plate onto the hindmost hole on top of the stove. Place
the connection pipe delivered with the stove in its rear wall opening. Push the stove into its place.
Make sure that the connection pipe settles well into the hole in the chimney. Tighten the space
between connection pipe and chimney with a flexible, fire-proof material such as fire wool.
Neaten the hole with a Kastor covering, available at your hardware store. The covering is
attached to the brick chimney surface with metal attachments or fireproof glue. (Picture 2.5.1.)
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
requiring protection must extend 100mm (4”) beyond both sides of the door and at least 400mm
(16”) in front of it. The protective layer should be a metal sheet with a thickness of at least 1mm
(1/16”).
2.5.1 Stoves with an extended door
The floors of the sauna and the room into which the stove door opens must be on an equal level.
The room with the stove door may also be on a lower level, but never higher than the sauna's
floor!
The stove and its extension must be installed on a sturdy, immovable, fireproof, level
surface. A cast concrete base is the best choice. If the floor of the room with the door in it
is flammable,
there must be a non-flammable protective layer (i.e. cast concrete or masonry) of
at least 60mm (2 7/16”) beneath the door extension. The fire protection measures on the door
side must also adhere to the instructions in chapter 2.3.
By adding fireproofing the stove and its door extension may also be installed on wooden
floors.
Nevertheless, the dividing wall must be non-flammable (brick, concrete or similar). For the
sauna and the extended door, a concrete slab with a thickness of 60mm (2 7/16”) is usually
acceptable (remember to take care of moisture draining). The fireproofing on the sauna side floor
must extend 250mm (10”) in front of the stove, 250mm (10”) at its sides and 250mm (10”) behind
it or, at the back and sides, up to a fireproofed wall. The fire protection measures on the door
side must also adhere to the instructions in chapter 2.3.
In unclear cases consult the local fire safety officials.
2.5.2. INSTALLATION THROUGH THE WALL AND FITTING THE FRAME ,
(KS-20, KS-20V,
KS-27V)
models, also with water tank
See also the instructions in chapter 2.6. concerning flue pipe installation.
Make sure that you have received the frame that belongs to the door extension (behind the
stove, between the packing hoop and the stove).
