INSTALLATION

Positioning the heater

• The heater must be positioned in such a way that there is a safe distance between flammable materials and the external surfaces of the heater. See Table 3.
• In installing the heater, it must be prevented that people could have physical contact with the heater or that other dangerous situations could emerge during the heating process.
• STEEL Mini holds approximately 132 lb (60 kg) of stones and STEEL holds approximately 330 lb (150 kg).
• The input of the power cable is located on the bottom cover of the heater.

Connecting the heater to the power supply

• A method to disconnect all poles from the mains (a circuit breaker) must be installed on the power circuit before the sauna controller.
• Only a certified electrician is allowed to connect the heater to the power supply.
• The power cable of the heater must meet the requirements of UL 62 in US and CSA 49 in Canada.
• It is recommended to connect the unit to the mains without an earth-leakage circuit breaker.
• The maximum current intensity in the cross-sectional area of the cable and circuit breaker are listed in Table 1 and Table 2.
•  The cable must be secured to the clamp on the cover screw.

NB! It is forbidden to use a non-heat-resistant cable with PVC isolation as the power cable. The joint box must be waterproof and it must be located up to 20 in (50 cm) from the floor.

• Open the cover of the heater’s electrical box.
• Attach the power cable on the terminal block according to the circuit diagram.
• Close the cover.
• Fix the cable on the output with a cable strap

Fitting the stones

• Make sure that the heating elements are not bent during the process.
• There must be sufficient air circulation around the heater elements.
• Stack the stones sparsely between the heating elements. If the stones have been stacked too close to each other, the heating elements may overheat (= shorter useful life) and slow the heating of the sauna.
• Stones with a diameter of 1.2-1.9 in (3–5 cm) are suitable for the heater.
• The stones on the external surface of the heater must be stacked close to one another. The heating elements must not be visible.
• Using ceramic stones in the STEEL heater is allowed at the user’s responsibility.

ATTENTION! Too sparsely filled stone container causes fire hazard!

NB! We recommend a specialist to lay the stones on the heater.

First-time use of the sauna heater

Before switching the heater on, the insulation resistance might prove to be lower than the standard. The reason for that is the moisture seeped into the insulating layer during storage in the warehouse and transportation. The moisture evaporates in 1–2 hours of heating the electric heater

Controlling the heater

All certified control panels may be used in controlling the heater.The output of the heater must remain in the interval determined by the control panel’s producer. Product can be used only with controlunit with timer function.Including other than those for installation in public saunas, shall be provided with a timer. For appliances for use in blocks of flats, hotels and similar locations, the operating period of the sauna heater shall be limited to 12 h with a minimum rest period of 6 h before any automatic restarting. For other appliances, the operating period of the timer shall be limited to 6 h, automatic restarting not being allowed.

Guard rails

• It is recommended to construct a guard rail around the heater. We recommend using materials with low heat capacity and bad thermal conductivity for the guard rail.
• Upon using flammable materials, it is necessary to leave the specified minimal safety clearances between the heater and flammable constructions.

ATTENTION! IF THE HEATER IS INSTALLED CLOSER TO FLAMMABLE CONSTRUCTIONS THAN AT THE DISTANCE OF THE MINIMAL REQUIRED PROTECTION BELT IT MAY CAUSE A FIRE HAZARD!

Wall materials and insulating the sauna room

In a sauna with electric heating, all massive heat accumulating wall surfaces (brick, glass brick, rendering etc.) must be insulated to use the electric heater with a regular output

The following sauna wall and ceiling construction is considered to be sufficiently insulated:

• a carefully installed insulation wool layer of 4 in, minimum 2 in (100 mm, min. 50 mm);
• the construction is damp proofed with taped aluminium paper or other reflective material;
• there is a 0.4 in (10 mm) air gap between the damp protection and boarding
• light wooden boards with about a 0.5-0.65 in (12–16 mm) thickness have been used for interior finishing;
• there is an air gap of at least 0.2 in (5 mm) on the edge of the ceiling panels at the upper part of the wall panelling

In order to use the heater with a regular output, it would be practical to bring the ceiling of the sauna lower regular 86.6 – 91 in, min. height of sauna room 86.6 in (2200–2300 mm, min. height of sauna room 2200 mm) so that the volume of the sauna room diminishes. The ceiling is insulated with an insulation layer at least 4 in (100 mm) thick and boarded according to the method described above. Wood should be used to cover internal surfaces; an exception may be made for heat resistant walls in the vicinity of the heater

ATTENTION! Insulating the heat barrier has to be approved by the fire inspector. Insulating flues in use is forbidden!

NB! Covering the walls or floor with light protective material, for example, mineral tiles that are installed directly on the surface of the walls or ceiling might cause the dangerous overheating of the wall or ceiling material.

Floor of the sauna room

The heater stones in use crumble due to temperature changes. The pieces and pebbles breaking away from the heater stones are washed on the sauna’s floor with the steam-making water. Hot stone parts may damage plastic flooring under and near the heater. Heater stone particles and sprays from the steam-making water (e.g., with iron content) may absorb into the light joints of a tile floor. In order to avoid aesthetic damage (caused by the reasons mentionedabove), ceramic tiles and dark joint filler should be used under and around the heater

Ventilation of the sauna

• In order to guarantee a sufficient supply of oxygen and fresh air, the sauna’s ventilation must be as efficient as possible. It is advisable to direct the fresh air into the sauna room from above the heater stones.
• As an alternative, the fresh air may be directed in from under the heater.
• The air inlet must be equipped with an adjustable valve.
• The exhaust valve must be installed in the opposite wall from the inlet valve at least 7.9 in (20 cm) above the height of the inlet valve.
• It is advised to install a ventilation valve at the upper part of the sauna room for the final ventilation

WARNING!

• Before turning on the electric heater, always check the sauna room and heater.
• The heater may be used only when it has been correctly filled with stones.
• Do not cover the heater—this causes fire hazard.
• Do not touch a working heater, it causes burns.
• Incorrect ventilation of the sauna room may dry the wood too much and cause a fire hazard in the sauna.
• Only tap water may be used for making steam.
• Never make steam by using a water hose.
• There must always be at least 2 in (5 cm) of fireproof heat insulation under the boarding.
• Sauna doors must always open outwards.
• Do not use the sauna for a purpose it is not intended for.
• Do not install more than one heater into the sauna room.
• Undiluted sauna essences etc. may ignite when poured directly onto the stones.
• Do not leave small children unattended in the sauna.
• Sudden cooling after staying in the steam room is not recommended for people with poor health. Consult a doctor.
• Enjoy the sauna as long as it is comfortable for you.
• Keep this information at a safe place.
• The product’s warranty guarantee does not extend to heating elements
