6. Use of Klapi heater
Warming up the heater
Before warming up the heater, ensure that there are no foreign objects that could create a fire hazard
in the sauna or within the safety distances of the heater.
Empty the ash pan to ensure efficient and clean combustion.
Stack the firewood in the firebox loosely to let combustion air reach between the logs. Place larger
logs on the bottom and the smallest one on top. Use logs with a diameter of about 8–12 cm. Fill
approximately 2/3 of the firebox with wood.
Place the kindling on top of the wood. Lighting the wood from the top generates the least emissions.
When lighting the wood, open the ash box door by 2–3 cm. Close the ash box door once ignition has
started.
The kindling should be lit from the top only. Close the door. Once the fire burns, close the ash pan.
The replacement air needed for combustion enters the top of the firebox through separate secondary
air channels. This ensures clean combustion and reduced wood consumption. If you leave the ash pan
open, smoke may enter the sauna. The door knob and the ash pan handle may become hot enough to
burn the skin when the heater is being heated. Use the tool supplied with the heater or equivalent for
handling the knob and the handle when the heater is hot.
Changing of the opening direction of the door
You can install the door of the firebox to open either to the right or to the left.
1) Remove the hinge shaft.
2) Lift the door off and turn it 180°.
3) Replace the hinge shaft.
