If you are looking for the ultimate sauna experience, look no further. The Harvia Legend 300 Duo is perfect for heating your sauna from outside or another room. The black steel frame shows off the abundant amount of stones that provide good heat even if the fire dies down. The grate frame also gives the stove a longer lifespan.
The Harvia Legend 300 Duo fire chamber has an innovative grate structure that separates the combustion air. Part of the air is directed to the upper part of the fire chamber. This way the burning is cleaner and more efficient. The direction of the door opening can be changed along with the adjustable legs making this wood-burning heater easy to place in your sauna.
NOTE: This heater requires stones for operation. The option below provides the required 572 lb of stones. (13 x 44 lb package of 10-15cm stones)
Please note that each natural stone is unique in shape and size. We recommend purchasing an additional box of sauna stones to allow you to choose the highest quality of stone for fit, form, and function.

The volume and structures of the sauna affect the selection of heater power. An average of 1 kW of heater power is required for each cubic metre of sauna volume. The power requirement increases if there are window surfaces or heat-storing surfaces such as brick, concrete or massive logs in the sauna.
One square metre of stone, glass or similar non-insulated surface increases the heater power requirement as much as if the sauna room volume were increased by 1.2 cubic metres. If the interior walls of the sauna room are made of non-insulated logs, the corresponding factor is 1.5.
If the heating capacity is too small, the heater needs to be heated longer and more intensely, which reduces its life span.
External control units are necessary for large heaters used in public facilities, but they are also well-suited for home use as long as the required electrical and sensor wiring is taken into account when planning the sauna.
Many heaters intended for home use are also available as so-called E models that utilise a control unit instead of operating switches on the heater. This is especially convenient when the heater is embedded into a bench.
All heaters have specific safety distances that determine how close the heater can be placed to walls and benches made of combustible materials. Greater heater power often corresponds with greater safety distances. The safety distance values can be found on the rating plate, the installation instructions, the brochure and the online product page of the heater.
The minimum safety distances must be adhered to in order to avoid fires!
When selecting an electric heater, you should pay attention to the control equipment and user comfort in addition to the visual look and heating power. Harvia heater models utilise three different control methods:
Fixed operating switches
External digital control panel
External control unit that takes care of the power input of the heater
The fixed, mechanical operating switches are placed on a side or at the top or the bottom of the heater.
If you wish to avoid bending down or your bench solution prevents manual access to the heater, you can select a heater model that is equipped with an external control panel or control unit. The external control panel can be installed in the dressing room, for example – it also shows the temperature of the sauna.
External control units are necessary for large heaters used in public facilities, but they are also well-suited for home use (consult your electrical engineer first).
All electrical appliances that are fitted with a protective housing, that is attached by screws to prevent dangerous live components from coming into contact with one another, must be installed and serviced, in compliance with the regulations in place, by a professional, authorised electrical engineer or any such other knowledgeable person.

A connection cable between the junction box on the sauna wall and the terminal strip of the heater is not supplied with the heater. The electrical engineer who connects the heater will supply the cable. The information of the connection cable can be found in the installation instructions of the heater and/or control unit.
A fault current protector must not be installed into the heater’s electrical circuit, as the heater is sufficiently protected when earthed. Fault current protectors are designed to ensure the safety of small electrical appliances, such as a coffee maker.
The silicone cable supplied with the sensor can withstand temperatures up to 170 °C. The cable can be extended with a lower temperature value cable with an equivalent cross section, provided that the temperature affecting the cable after the connection does not exceed 80 °C.
The sensor must be placed exactly as prescribed in the instruction manual in order to ensure that the heater works correctly.
Please note! The supply air vent of the sauna must not be near the temperature sensor. The air stream near the vent will cool the sensor, resulting in the sensor sending erroneous temperature information to the control unit. This may cause the heater to overheat. Minimum distance between the supply air vent and the temperature sensor:
non-directional vent: 1,000 mm
vent directed away from the sensor: 500 mm
If the minimum distance cannot be adhered to, the ventilation system must be altered.
Installing a wood-heated stove and an electric heater in the same sauna
The safety distance requirements for both the heater and the stove must be met. See the installation instructions of the heater and the stove for the safety distance requirements.
The distance between the heater and the stove must be their respective safety distances combined, however no less than 600 mm. This safety distance can be reduced with a protective sheath for the wood-heated stove.
ERROR MESSAGE ER1

Moderna, Fuga, Delta, Kivi, Cilindro: The measuring circuit of the temperature sensor is broken. Contact service.
ERROR MESSAGE ER2
Moderna, Fuga, Delta, Kivi, Cilindro: Short-circuit in the measuring circuit of the temperature sensor. Contact service.
ERROR MESSAGE ER3
Forte: The measuring circuit of the overheat protector is broken.
ERROR MESSAGE ER4
Forte: Disrupted connection between the lower and upper card.
ERROR MESSAGE ER5
Forte: The temperature surrounding the control panel is too high.
Water thrown on the heater cools the stones quickly.
Make sure that the fuses/breakers of the heater on the electrical panel are in working order. Please note that there are one to three fuses/breakers on the electrical panel, depending on the heater model and electricity system.
Check that all the heating elements are glowing when the heater is on.
Set a higher temperature.
Make sure that the heater is sufficiently powerful.
Check the heater stones. If the stones are stacked too tightly, compacted over time or the wrong kind, air circulation in the heater may be blocked, which in turn decreases the heating power.
Make sure that the ventilation of the sauna is arranged correctly.
Test whether the thermostat works correctly:
Remove stones from the heater until you can see the ends of all heating elements.
Turn the heater on. The heating elements will begin to glow. If a heating element does not glow, it must be replaced. Remember to close the sauna door.
Monitor when the heating elements turn off. This happens when the sauna temperature has reached the desired temperature set with the thermostat. Usually, the desired temperature will be reached in 35–45 minutes from turning on the heater. If it takes significantly longer to reach the desired temperature, the temperature sensor may be placed incorrectly, the heater may not have enough power, or the thermostat may be faulty.
Check the data cable and its connections.
Water thrown onto the heater does not vaporise and runs through the stone compartment.
Set a lower temperature.
Make sure that the heater is not too powerful.
Make sure that the ventilation of the sauna is arranged correctly.
Make sure that the safety distance requirements are met.
Check the heater stones. If the stones are stacked too tightly, compacted over time or the wrong kind, air circulation in the heater may be blocked, which can cause overheating in the structures (especially when an electric heater is used).
It is perfectly normal for the wooden surfaces of the sauna to darken over time. The darkening may be accelerated by
– sunlight
– heat from the heater
– protective agents on the walls (protective agents have a poor heat resistance level)
– fine particles coming off the heater stones and lifted by the air flow
Wood-heated saunas: smoke that enters the sauna when adding firewood, for example
If the heater is new, it may still have residual protective agents from the manufacturing process. Carry out the first heating in a well-ventilated room.
The hot heater may emphasise smells mixed in the air that are not, however, caused by the sauna or the heater. Examples: paint, glue, heating oil, spices.
The timer switch is a mechanical device that emits a ticking sound when working normally. If you hear ticking even though the heater is off, check the connections of the timer switch.
Occasional bangs are usually caused by stones splitting due to the heat.
Thermal expansion in the heater parts may cause sounds when the heater is heating up.
The ash box is full. A full ash box prevents air circulation within the stove. Empty the ash box.
There are leaks in the flue connection. Seal the connection.
The smoke ducts of the stove are blocked. Clear the smoke ducts through the sweeping openings of the stove.
The flue connection pipe is too deep in the flue. Shorten the flue connection pipe and/or pull the stove and the pipe further from the flue.
The burning material is moist or its quality is otherwise low.
The flue does not have a good draught.
The smoke ducts of the stove are blocked. Clear the smoke ducts.
The burning material is moist or its quality is otherwise low.
The smoke ducts of the stove are blocked. Clear the smoke ducts.
Check how the stones are stacked. Remove small pieces of stone and stones that are less than 10 cm in diameter from the stone compartment. Replace disintegrated stones with large and undamaged ones.
