Flame pattern
9) As soon as the pieces of firewood are burning well all
around (light, high flames), you can control the air
supply with the controller.
ð
Control at maximum setting right = maximum heat
output
ð
the flames should always burn yellow and never
blue or with black flame tips (otherwise feed more
air in).
blue = too much air
black = too little air
ð
During combustion doe not totally close the air
supply (danger of deflagration!).
12.3 Heating in the transition period
In the transition period, i.e. during high external temperatures, a sudden temperature rise can disrupt
the chimney draft so that the fuel gases are not completely drawn off. In this case the appliance must
be filled with smaller quantities of fuel and operated with the air damper/-controller on a higher set-
ting so that the available fuel combusts more quickly (with a flame developing) and the chimney draft
stabilized as a result.
TIP
To prevent resistance in the firebed, the ashes should be removed more frequently.
