2. OPERATING PRINCIPLE
Firewood (coal, briquets) is burnt on the ceramic grate on the basis of the rotary /
lower combustion principle. Combustion air flows precisely where needed: to the
furnace top, onto the fire bar, and down the bar into the firing throat for the final
combustion phase to occur.
3. BOILER INSTALLATION
Always connect the burner to an energy storage battery of 500 to 2000 l as
appropriate for the application. For example, one fill of the furnace with dry birch
wood heats 1000 l of water / nonfreeze medium up to approximately 45ºC. For
equipment connection examples see Fig. 3 and 4.
Connect a 1.5 bar relief valve to the boiler nozzle ensuring that the steam blow
capacity of the valve matches the power of the boiler.
The pre-pressure of the membrane expansion tank must be e.g. 0.5 bar and the
volume of the tank must be at least 7 % of the entire water volume of the system.
Mount a deaeration valve onto the top of the system pipework.
The cooling coil provides even more safety. While installing the boiler, connect
the anti-boil thermal valve to the coil (optional supply).
For the valve connection see Fig. 2.
After filling the pipework connection, take care to ensure that potential leakage
could not damage the boiler.
