2.6. Connecting to a Helo chimney.
The Kastor stove can be connected from the top to a factory built Helo chimney. (check 2.4).
Make sure to choose the correct chimney type with regard to your stove model, chimney height, temperature class T 600,
exterior circumstances etc. For best results we recommend that you install a chimney valve.
•
Install the heater's own connecting pipe to the upper flue opening on top of the heater.
•
Install a no insulated connection pipe and any necessary extension piping on top of the stove's own connecting pipe.
Where necessary, saw the connection pipe and the extension pipe down to suitable size.
•
The chimney valve goes between the insulated and no insulated sections or into the first insulated pipe section.
•
Continue from the chimney valve with an insulated pipe. The insulated pipe section must start at least 400 mm
beneath the ceiling. Follow the installation and usage instructions for Kastor chimneys.
Remember to keep all safety distances to flammable and non-flammable materials named above. Helo Oy does
not guarantee the suitability and functioning of other manufacturers' factory-built chimneys with Kastor stoves.
Helo Oy does not accept liability for the quality of other manufacturers' factory-built chimneys. The chimney must
fulfil the requirements of temperature class T 600.
2.7. The stove door and changing the opening direction
The opening direction is changed by turning the door upside down.
Changing the door's left/right-handedness:
•
Open the door and push the hinge pin out of the lower hole.
•
Pull the pin downwards out of the upper hole to release the door. Remember the washers.
•
Turn the door into the desired position.
•
Slip the hinge pin first into the sleeve's upper hole and the washers on top of the sleeve onto the pin. (The risers on
the pin must be at the lower end.)
•
Slip the door's upper hole onto the hinge pin above the sleeve.
•
Finally, guide the hinge pin into the lower holes of the sleeve and the door.

2.8. Grate

There is a grate in the heater's stove. Place it on brackets on the bottom of the stove.
2.9. General directions to prevent damage
When you bring the stove into the sauna, before you add the stones, burn a full load of wood in a well ventilated
sauna to burn off the last protective substances and harden the coating.
Kastor heater is ready to be used after burn-ins completed outdoors and indoors, and after stones have been
added.
Please read and follow the instructions below:
Wood quantities can be found in table (2).
•
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 door.
•
The stove's operating life shortens, if it is constantly heated to a red glow.
•
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 applyifthe stoveis usedsea water.
•
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.

3. Using the stove

3.1. 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 33cm. Dampness 12–20%. NOTE! Damp or decayed
wood does not provide heat very well and emissions are higher.
It is not permitted to burn treated wood, wood with nails, plywood, plastic, plastic coated cardboard or paper in this
stove. Fluid fuels must not be used even while starting the fire to avoid dangerous flash fires. Do not burn full
loads of very small wood such as shavings and splinters, as they produce excessive 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.
