PRIOR TO INSTALLATION

Perform the following checks:

• The stove is the right size (kW) for the size of the sauna (m3).
• Table 1 shows the sauna volumes for different stove types.
• For every 1 m2 of uninsulated brick, tile or glass wall surface in the sauna, increase the sauna volume by 1.5 m3 when choosing the required stove wattage from Table 1. The sauna volumes indicated in Table 1 are both maximum and minimum values.
• Table 1 indicates both the minimum height of the sauna and the minimum safety distances for the stove.

INSTALLATION

INSTALLATION OF STOVE

• Ultra Small can also be fastened to the wall. See Fig 3.
• Observe the safety distances (Fig. 1) when installing the stove.
• The electrical connection of the stove may only be carried out by a qualified electrician in compliance with valid regulations.
• The connection cable shall be a rubber-sheathed cable of type H07RN-F or corresponding. Cable size and fuse rating as indicated in Table 1.
• The diameter of the wiring running from the stove to the electric heating control and to the signal lights of the house shall correspond to the size of the connection cable.
• The protective film of the heater casing and the cardboard support of the resistors need to be removed before using the product.

LOADING OF STONES

• Use safety gloves.
• When loading the stones, make sure they do not bend the resistors or obstruct the sufficient circulation of air.
• Do not load the stones too tightly. Overfilling of the stone compartment will cause overheating of the resistors (= shorter service life) and slower heating up of the sauna.
• Suitable stones for the stove are 5-10 cm in diameter.
• The stones shall cover the heating resistors completely.
• Sauna stones must be replaced every 6 months.

AN UNDER-FILLED STONE COMPARTMENT WILL CAUSE A FIRE HAZARD!

VENTILATION IN THE SAUNA

• The ventilation in the sauna should be as efficient as possible in order to ensure a sufficient oxygen level and freshness of air. We recommend that the fresh air intake is located near the stove (but not closer than 50 cm).
• The fresh air intake shall be equipped with an adjustable valve.
• The exhaust valve shall be at least twice the size of the fresh air intake.

The exhaust valve can be installed on the opposite wall, at least 20 cm higher than the fresh air intake.

**CONSTRUCTION OF SAUNA

**

The sauna shall be well heat insulated, particularly the ceiling, where most of the steam rises. Due to the high level of humidity, the heat insulation should be covered with moisture-proof material, such as aluminium paper. Wood should always be used for cladding.

IMPORTANT ADDITIONAL INSTRUCTIONS

• A suitable temperature for the sauna room is between 60–80 °C.
• Staying in the hot sauna for a longer time, makes the body temperature rise, which may be dangerous. Do not sleep in the sauna.
• You should be careful in the vicinity of the hot heater, because the stones and metal parts of the heater may cause burns.
• Only a small amount of water (1-2 dl) should be thrown onto the heater stones because the steaming water is scalding hot.
• This equipment is not to be used by children or people whose physical and psychological traits, mental functions, lack of experience or knowledge may hinder the safe operation of the equipment if the person who is responsible for safety cannot supervise them or instruct them in the use of the equipment.
• Do not go to the sauna if you are under the influence of substances causing intoxication.
• Children may not be left unsupervised and they should be supervised to make sure they do not play with the equipment.
• Always inspect the steam room before plugging in the heater.
• The improperly filed stone container is a fire hazard.
• Covering the stove will cause a fire hazard.
• Do not place any objects top over the heater or dry clothes near by the heater.
• Door and window must be closed when using the heater.
• The stainless steel casing may change its color because of the heat, which is normal behavior for the material. Color changes are not covered by the warranty.
• Use normal domestic water for steam water. Do not use seawater (or other salty water) or chlorinated water.
• Sea air and a humid climate fastens the corrosion of the heater.
