-
cumulator tank.

Ceramic combustion chamber
The combustion chamber is designed for reverse combustion.
The depth of the combustion chamber is 550 mm. A bypass
damper prevents smoke entering the room when firewood is
added.
Flue cleaning
All flue ducts in the boiler are cleaned from the same hatch at
the front of the boiler. The hatch is hinged and is opened with a
single operation. The flue ducts are round, which means there
are no awkward corners when flue cleaning.
Chimney
The Vedolux 37 has a suction fan minimising the chimney re
-
quirements of the boiler.
Accumulator tank
To optimise combustion and efficiency, and to meet environ
-
mental requirements relating to firewood burning, the boiler
must be connected to an accumulator tank. The accumulator
tank is dimensioned according to the requirements of the build-
ing.
