We recommend round structural clay stones for the sauna stove. Lay the stones in layers,
larger ones on the bottom and gradually smaller ones towards the top. (2.1)
Use 20 kg of 100 mm stones on the bottom, next 40 kg of 80 mm stones, then 10 kg of 60mm
stones, and finish with 5-10 kg of small stones.
When there's a fire in the stove, make sure the stones heat up evenly. If necessary, relay the
stones so that the flue gas flows evenly throughout the stove's space for stones.
In order to operate properly, it is vital that the hot flue gases can flow freely in between the
stones and heat them up quickly. If the stones on the bottom are too small or incorrectly
laid, the heating will slow down.
Check the condition of the brick grate and the stones once per year. Replace them when
necessary.
3.5. Damper plate / joining pipe
The damper plate is installed so that the handle points upwards. The damper plate is open
when turned right.
4. Burn-in

The first heating may produce some odour. The purpose of burn-in is to burn the protective
agents off the stove. Burn a few full furnaces of wood so that the stones become red-hot in
the middle of the space for stones. Normally heating takes 3 full furnaces of wood.
Make sure there's ample ventilation during the first heatings.
5. General directions to prevent damage
Please read and follow the instructions below:
Wood quantities can be found in table (2).

Remember to leave at least 10 cm of free air space as measured from the flame plate
downwards to aid the burning process.

Do not heat immediately at full blast, if it is cold. The brick chimney might suffer damage.

Do not throw water directly at the glass

The stove’s working life will be shortened significantly, if it is subjected to salt water. Note
that in close proximity to the sea even well water may contain salt.The warrenty does not


Factors influencing the stove’s useful life are, among other things, how well its size is
suited to the sauna, the fuel used, how often it is used, failure to follow these instructions
and general carefulness.

Kastor stoves have been very carefully designed and tested. On the basis of our studies,
we at Helo Oy know that if the stove suffers damage in a very short time (e.g. the walls
split or burn through, the top burns through etc.), the stove has not been used according
to instructions. Helo Oy does not take responsibility for damage through failure to follow
the user’s manual.
6. Using the stove
6.1. Fuel
Only unprocessed wood can be used as fuel in Kastor heaters, preferably chopped, birch or
alder (batch size can be seen in table 2). The length of firewood is approximately 30cm.
Dampness 12–20%. NOTE! Damp or decayed wood does not provide heat very well and
emissions are higher.
