INSTALLATION MANUAL
ELECTRICAL SAUNA STOVES - NME 450, NME 600, NME 900
1. THE ELECTRICAL SAUNA STOVE PACKAGE INCLUDES:
- Sauna stove jacket
- Stone basket with control device
- Mounting plate + anchor screws
- Installation instructions
2. BEFORE INSTALLATION
Check the following:
- The sauna stove is the right size (kW) for the size of the sauna (cu m).
- Table 1 shows the volumes of the sauna for the different types of stoves.
- If the sauna has non-insulated surfaces, for instance brick, tile or glass, 1.5 cu m must
be added to the sauna volume for each square metre of wall on the basis of which the
effect needed for the sauna stove is dened according to Table 1.
The volume values of the sauna according to Table 1 must not be exceeded
or lowered.
- The minimum height of the sauna and the distances of the minimum protected areas
have been dened in Table 1.
- Make sure that there is a sufciently steady mounting plate for the anchor screws.
A thin panel alone is not enough. Additional supporting rails behind the panel or
reinforcement boards on the top of the panel which are fastened to the wall support can
be a reinforcement.
- Sauna stoves NME-450 and 600 can also be installed in a wall recess where the
protected areas must be considered according to Figure 1.
- Stove NME-900 must allowed to be installed in the wall recess.
ONLY ONE ELECTRICAL STOVE MUST BE INSTALLED IN THE SAUNA.

3. INSTALLATION
Fasten the mounting plate to the wall with the screws which follow the delivery according
to the picture 2.
Stage 1: ELECTRICAL CONNECTION
- The connection of the sauna stove to the electrical network can only be carried out by
a qualied electrician in accordance with the valid regulations.
- A rubber cable of type H07RN-F or similar must be used as a connection cable.
The
cross-sectional surface of the cable and the size of the fuse can be seen in Table 1.
- The cross-sectional surfaces of the wires which are connected from the sauna stove to
the heating and signal lights must correspond to the feed cable of the sauna stove.
- First connect the connection cable to the terminal strip in the connection box of the
sauna stove.
- Turn the stone room+electrical box upside down.
- Open the bottom of the electrical box.
- Connect the connection cable.
- Fasten the bottom of the box.
- Turn the stone room+electrical box right
side up.
Stage 2: INSTALLATION ON THE WALL
- Draw in the lugs on the rear side of the
sauna stove through the mounting slots of the
mounting plate on the wall (Fig.6A).
- Push the upper edge of the mounting
plate between the jacket and upper frame of
the sauna stove and make sure that the lugs
of the stove are wedged into the slots of the
mounting plate on the wall (Figure 6B).
- Tighten the upper edge of the sauna
stove
with a locking screw (Figure 6C).
- The stone basket is now locked in the jacket and on the mounting plate of the sauna
stove.

Stage 3: TO PILE THE STONES
- The stones are piled on the top of the re grate in
the stone capacity, in between the heating elements
(resistors) so that the stones support each other. Please
make sure that the resistors are not supporting the
weight of the stones.
- When piling the stones, make sure that the resistors
are not bending and there is sufcient air circulation.
- Do not pile the stones densely. A stone basket which
has been lled too densely causes overheating of the
resistors (= a shorter lifetime) and slows down warming
up the sauna.
- The stone size diameter suitable for the sauna stove
is 4-7 cm.
- The stones must completely cover the heating
resistors (Figure 7).
BEFORE YOU CONNECT THE SAUNA STOVE ALWAYS CHECK THE STEAM ROOM.
A STONE BASKET WHICH HAS NOT BEEN FILLED COMPLETELY CAUSES A FIRE
RISK!
Use of ceramic stones that are light, porous and of the same size is prohibited, as they
can cause the resistors to heat up too much and break. Similarly, soft soap stones
cannot be used as sauna heater stones.
4. AIR CONDITIONING IN THE SAUNA
- The air concitioning in the sauna must be arranged as effectively as possible to get
sufciently oxygen and fresh air. The best way is to direct fresh air near the sauna
stove (not closer than 50 cm).
- The ventilating air pipe must be equipped with an adjustable valve.
- The size of the bleed valve must be twice as big as the fresh air valve. The bleed
valve can be installed on the wall opposite the sauna stove at least 20 cm higher than
the fresh air valve.
5. CONSTRUCTION OF THE SAUNA
The sauna must have good thermal insulation, especially on the ceiling through which
the steam mostly tends to evaporate. Owing to the damp, it is recommended to protect
the thermal insulation of the sauna with something which does not let damp penetrate,
for instance aluminium foil. The cladding must always be wood.

6. SAFETY RAIL
If needed, a safety rail can be built round the
sauna stove (Figure 9).
We recommend wood for this, in this
case, the minimum distances stated for
amable constructions must absolutely
be followed. Incorrect installation can
cause a re risk.
During the insulation resistance
measurement of the sauna heater, the heater
might leak. This is due to the dampness
that has seeped the insulator material
of the heating resistors during storing or
transportation. The resistors will be dry only after they have been warmed up a few
times. Do not switch the electrical sauna heater on using the fault current switch!
