Other factors contributing to the heater life-cycle are correct size for the space, the fuel used, the number of heating
cycles, failure to follow instructions when using the heater, and general diligence.
•
Kastor heaters are carefully designed and tested. If a heater becomes damaged in use in an unreasonably short time
(e.g. the covers or top part are torn or burned through etc.), it can be fairly said on the basis of research data that the
heater has not been used as instructed. TylöHelo Oy will not be liable for damage resulting from misuse or use against
instructions.
If several full batches of wood are burned in the heater consecutively, the heater and the pipe will become
overheated, which might result in an increased risk of fire.
8. Using the heater
8.1. Fuels
Only unprocessed wood can be used as fuel in heaters, preferably chopped, birch or alder (refer to Table 2 for batch
sizes). The length of firewood is approximately 33 cm. Dampness 12
–20%. NOTE! Damp or decayed wood does not
provide heat very well and emissions are higher. Do not burn any wood still in the extension component; wood must only
be burnt in the furnace proper.
The amounts of wood mentioned in Table 2 correspond to the values of a nominal output test in compliance with EN-
15821, where the volume of the sauna room is the maximum volume. When heating the sauna for the first few cycles,
use smaller amounts of wood than listed in the table to find the ideal batch size for your sauna.
Do not exceed the amounts of wood mentioned in the table
The following materials are not allowed in the heater furnace: impregnated wood, wood containing nails, chip board, plastic,
plastic coated board or paper.
Liquid fuels are not allowed, not even when starting the fire because of the risk of a flash fire. Do not burn large amounts of
small pieces of wood, such as chips or small pieces because of their high temporary heating effect.
Firewood must not be stored immediately next to the heater. Pay attention to the heater's safety distances.
8.2. Adjusting the air flow
The heater has been designed to perform best when the negative pressure of the flue is approximately
–12 Pa. If the
chimney is long, this optimal negative pressure limit may be exceeded. Adjust the draft and combustion air flow using a
damper so that it is suitable. Be careful of carbon monoxide. The damper must not be closed too far!
When lighting the fire, the door may be kept slightly open for a moment. The ash pan must be closed and it may not be
opened during burning.
Combustion air comes from another source.
8.3. Adjusting heating efficiency
The amount of wood when stoking determines the heating efficiency. For the correct amounts of wood that ensure that the
wood burns in line with the CE marking, refer to Table 2.
The heating efficiency depends on the quality and the amount of fuel.
8.4. Lighting
•
Place the first batch of wood loosely in the furnace. Table 2
•
Add kindlings between the logs and light them.
•
You can keep the fire door ajar for a moment while the logs start to burn.
•
Do not burn any wood still in the extension component.
8.5. Stoking the furnace
Add another batch of wood when the fire has nearly burned down to embers. Table 2
Add the wood lengthwise, i.e. parallel to the grate opening. Close the fire door.
The sauna room is normally ready for bathing in 40 to 60 minutes.
If several full batches of wood are burned in the heater consecutively, the heater and the pipe will become
overheated, which might result in an increased risk of fire.
9. Maintenance and repairs
9.1. Cleaning the heater
The surface of the heater may be cleaned with mild detergent and moist, soft cloth.
Clean the fire door glass with a soot cleaner agent (e.g. Noki Pois) available from hardware stores.
Clean the stone compartment and check the condition of the stones approximately once every six months.
9.2. Removing the ashes
Excess ash will shorten the grate's life cycle and weaken burning. Fresh air enters the furnace through the heater back
wall under the grate, which is why it is important to remove ashes from the heater before using it again (Figure 3).
Always remove the ash before using the heater, unless the ash is still hot.
