Space heating capacities
The size of the heated space depends on the heating conditions and thermal insulation.
Subject to the heating conditions, with individual heat sources of rated output 9 kW, it is possible to heat up
the following space volumes:
Occasional heating or intermittent heating should be considered as less favourable or even unfavourable
heating conditions.
Chimney selection
Chimney dimensioning to DIN 4705 should be based on the following data:
Rated heating output [kW]
Flue gas flow rate (m)
Mean flue gas temperature downstream the flue connection
Minimum required negative pressure in the chimney [p] at rated output
Minimum required negative pressure in the chimney [p] at 0.8-times rated output
Remember:
• When reloading, make sure to load a quantity of fuel that is most suitable in respect of the actual
heating requirements.
• After reloading, open the air supply control as required until bright fire is developed. Only then, set
the air supply control to the position corresponding to the desired heating output.
• Strictly observe these Installation and Operating Instructions.
• Over the night, keep the air supply control closed to maintain the ember bed until the next morning to
set the new fire easily with dry kindling.
• When cleaning, i.e. removing the ash, make sure that sufficient ash is left to cover the entire lower
plate at the undulated ribs level and thus to ensure long-lasting ember and to protect the lower
plate.
