3. USINg THE STOvE
3.1. FUEL
Use only untreated wood in Kastor stoves, preferably sturdy
split logs of various wood, such as birch or alder. The logs
should at most be 35 cm long. Wet or foul wood does not heat
very well.
It is not permitted to burn treated wood, naily wood, plywood,
plastic, plastic coated cardboard or paper in this stove. Fluid
fuels may not be used even while starting the fire, since it
might damage the grate. Do not burn full loads of very small
wood such as shavings and splinters, as they produce exces-
sive heat for short durations.
The fuel logs must not be stored in the immediate vicinity of
the stove. Remember the safety distances. Only bring into the
sauna as much wood as you can fit immediately into the fire
compartment.
3.2. USAGE WITH VK-20 WATER TANK
KT-S and KT-H stoves can be equipped with the water tank VK-
20 (28 litres). The tank may not be used for anything else but
the heating of water. Note the following:
• The tank must always be at least half full of water when
there is a fire in the stove.
• Make sure that the tap is always closed tightly.
• The heated stove heats up the water tank’s tap.
• Empty the water tank after use.
• Leaving water in the tank to freeze will break it.
3.3. ADJUSTING THE AIR FLOW
The stove has been designed to work best when the chimney’s
underpressure is about 10–20 Pa. If the chimney is tall, this
optimal underpressure limit is easily exceeded. This excess
can be noticed as follows:
• The air flow cannot be adjusted with the ash door.
• The flames reach into the connecting pipe and even up to
the chimney.
• The humming noise of the burn feels loud.
• Looking through the glass door, the flames rage with great
strength towards the stove’s upper part.
• The sauna and/or stones do not heat up properly in less
than an hour (although the stove has the correct size).
When you light the fire, the chimney valve and ash compart-
ment door must always be open. Once the fire has taken hold
and burns well, adjust the air flow with the ash compartment
door. Usually, depending on the draft, the ash door is kept open
by about 0.5–2 cm.
The stove’s basic draft is just right, when the burning can be af-
fected by the ash door and the flames rise calmly. This brings
the cleanest burning, although it warms up somewhat more
slowly than in a stronger draft.
If the basic draft is too strong, it can be adjusted by setting a
fireproof piece of brick or an optionally available draft adjust-
ment plate inside the stove’s upper part, on top of the arched
flame plate. If that does not help, the basic draft may be ad-
justed with the chimney valve. Do not close the chimney valve
too much – carbon monoxide poisoning hazard!
3.4. ADJUSTING THE HEAT OUTPUT
The heat output is affected by the quality and amount of fuel.
Do not burn excessively long logs in the stove. Take care not to
heat the stove constantly to a red glow.
3.4.1. A SAUNA bATH ON JUST ONE LOAD OF WOOD,
LIGHTING FROM bELOW
• Place two smallish logs lengthwise in the fire compartment.
• Add some lighting aids between the logs and light them.
• Then place a few logs crosswise on the previous ones.
• Close the door and leave the ash compartment door open
by about 3 cm.
Once these latest logs have burned some five minutes,
straighten them into the grate direction and fill the fire com-
partment lengthwise with solid split logs. Close the door and
leave the ash door open by 3 cm for a short while.
After this, slow down the burning by closing the ash door gap
to 0.5–2 cm. During this heating phase, the fire compartment
walls should only heat up for a while to a red glow in their
upper parts. Usually, this will prepare the sauna for your bath
in about 40–50 minutes, and you should not need to add
firewood during your stay.
