Firewood burning 

 

Position the power switch (6) to ON. 

 

Put about eight 50 cm long pieces of 
wood evenly onto the fire bar, altogether 
weighing about 6 kg, and insert paper or 
birch bark in between to ensure ignition. 

 

Fire the wood and start the smoke ex-
hauster by rotating the thermostat to posi-
tion 0. The filling hatch is kept slightly 
open during ignition. 

 

Wait 15-20 minutes to allow about a 10 
cm layer of live coals to form on the bar.  

 

Charge blocks (about 18-20 birch logs 
altogether weighing about 32 kg) evenly 
and closely, bark upward, onto the bar so 
that the blocks touch the rear wall of the 
furnace. 

 

Set the smoke exhauster thermostat to the 
setpoint which is about 90 ºC. The set-
point is correct if the smoke exhauster 

stops when there is a small amount of 
coals left in the boiler.  

 

Put new blocks onto the remaining coals. 

One firewood charge will burn about 2.5 
hours producing about 100 kW heat, i.e. a 
1800 liter energy accumulator will be heated 
to approximately 50 ºC. 

If the boiler has not been used for a long 
while, use a small amount of firewood for the 
first burning to avoid bar splitting by boiling 
water that could soak in the ceramic fire bar. 

Charge the firewood on the fire bar so that 
it does not block the firing hole located in 
the middle of the bar.
