  Use the factory sleeve (inside of the stove) to mount the chimney adaptor on. Then fit the 

sleeve onto the output on the stove. 

 
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. The handle must also be 
reversed. Open the handle's 2 attachment screws turn the handle upside down and attach the 
screws. 
 

x

  Open the door and push the hinge pin out of the lower hole. 

x

  Pull  the  pin  downwards  out  of  the  upper  hole  to  release  the  door.  Remember  the 

washers. 

x

  Turn the door into the desired position. 

x

  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.) 

x

  Slip the door's upper hole onto the hinge pin above the sleeve. 

x

  Finally, guide the hinge pin into the lower holes of the sleeve and the door. 

2.8. Air guide plate 

In the back part of the stove’s fire compartment is a removable air guide plate. (Picture 2.8. /1.) 
The stove must not be used without the guide plate! If it gets worn out through use, twisted or 
otherwise damaged, it must be replaced. 

 

Replacing the air guide plate 
Remove the grate. Install the air guide plate in the fire compartments back so that its support part 
is on the grate support. Check the plate’s condition regularly. (Picture 2.8. /2.) 

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. 
 
Once the outdoor burn-in has been performed, the stones arranged and the water tank, if 
installed, filled, your Kastor stove is ready for use. Make sure that the air guide plate is in place 
as shown in picture 2.8./2. 
 
Please read and follow the instructions below: 

x

  Remember to leave at least 10 cm (7/16”) of free air space as measured from the flame 

plate downwards to aid the burning process. 

x

  Do not heat immediately at full blast, if it is cold. The brick chimney might suffer damage. 

x

  Do not throw water directly at the glass door. 

x

  The stove’s operating life shortens, if it is constantly heated to a red glow. 

x

  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. 

x

  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. 

x

  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
