x

  Install the connection pipe delivered with the package into the backmost flue opening on 

top of the sauna stove or the hole in the back wall. KS models: remove first the cap in the 
mantle e.g. with a screwdriver and move the covering plate to the upper flue opening. 

x

  In JK models the connection pipe is installed to the hole nearest the door on top of the 

stove. 

x

  Other openings are for sweeping; cover also them with a cap. 

x

  Burn-in: The purpose of the burn-in is to remove out of doors any flammable protective 

coating substances and to harden the stove’s coating. Burn a few full loads of wood in the 
fire compartment. Continue the burn-in until there are no more fumes rising from the 
stove. 

x

  Once the stove has cooled down after the burn-in, move it into the sauna. 

x

  See to it that the sauna is well ventilated during the first couple of heating.
