3. Installation and
preheating of the sauna
heater
3.1 Preheating
Before use and arranging the stones, the sauna heater
must be heated to remove the protective agents. Any pro-
tective films and stickers must have been removed before.
Preheating shall be carried out on a non-combustible
surface and outside
, since paint emits harmful solvent
vapours and smoke during the heating. Use of a connec-
tion pipe included in the delivery of the sauna heater in the
upper joint (see item 1 of the attached drawing) improves
draft during preheating. 1–2 fireboxes of wood are suffi-
cient for preheating. After preheating and before arranging
the stones loose cover material should be removed from
the stone compartment of the sauna heater with a steel
brush. In case the external surface of the sauna heater is
painted, it should not be rubbed or wiped before the first
heating. The paint of the sauna heater will achieve suf-
ficient strength only after the first heating. Do not create
steam during the first heating.
NB! If the sauna heater is equipped with a water tank
please check before preheating that the water tank faucet
and safety plug are installed and that the
tank is filled
with clean water.
3.2 Regulation of the height
The legs of the sauna heater are adjustable and can be
used for levelling the sauna heater and for adjusting the
height. There must be an air gap of at least 25 mm between
the sauna heater and the floor. Use a spirit level to check if
the sauna heater is level.
3.3 Connection with the smoke flue
The sauna heater can be connected to the smoke flue from
the back or top of the sauna heater. Seal the unused open-
ing with the supplied cover. The sauna heater comes with
a short smoke flue connection pipe, which can be used
to connect the smoke flue of the sauna heater from the
back. Only a straight connective flue without extra parts
can be used, when the flue is connected from rear. If the
connection with the smoke flue is done from the above,
Kota connective flue or Kota smoke flue must be used. In
case of connection from the above, a Kota smoke flue tank
for heating water or a Kota stone basket can be installed
around the connective flue.
Do not push the connective flue too deep in the smoke
flue, because this would hinder the draft. Any leaks in the
connective flue also reduce the draft; therefore, the con-
nections must be sealed with fireproof sealing material.
Leakage in the connective flue cause combustion gas-
es formed in the sauna heater to ignite in the flue.
The
connection joint of the flue and the sauna heater must be
25 mm. The diameter of the connective flue of the sauna
heater and the height from the floor are shown in clause
1.1.
Please consider with the clearance distance of the modular
smoke flue, see the manufacturer’s instructions.
