Operating Instructions SP Dual compact | B1500319_en
Observe the following basic conditions:
❒ Only use fuel permitted according to the operating instructions
➥ Ensure that the water content (w) is greater than 15% and less than 25%
❒ Use short split wood (edge length EL < 10 cm) to create the measuring conditions
and for the measurement itself
❒ The fuel must be dry, clean and uncontaminated (not painted, glued, etc.)
❒ The combustion process must not be interrupted during the measurement
Interruptions to the combustion process include:
- Opening the boiler doors
- Stoking the burning material
- Switching off the ID fan (e.g. because of inadequate heat consumption)
❒ Fill the boiler approx. 1/4 full with small pieces of split wood in accordance with the
operating instructions and heat up
➥ TIP: The smaller the wood is split, the better and faster the bed of embers
forms
❒ Ensure that the operating conditions are fulfilled
➥ Return temperature min. 60 °C, boiler temperature min. 70 °C, chimney
draught in the range of 8-10 Pa
❒ Allow the fuel to burn off until a basic firebed is achieved
➥ This will take at least one hour depending on the fuel used and the power
consumption
❒ Open the fuel loading door, distribute the embers evenly with the furnace tool and
gauge the height of the embers
➥ The top row of holes in the combustion chamber guards must be visible
❒ Close the fuel loading door
Once the basic firebed has been achieved (top row of holes visible in the combustion
chamber guards, the two lower rows of holes of the combustion chamber guards are
covered with embers):
Short split wood with an edge length EL < 10 cm
The term "short split wood" has been defined in these
instructions by Froling; there is no fuel standard or similar
guidelines for this.
