1.1 Safety precautions
The boiler and related accessories are state of the art and meet all applicable safety regulations. Your boiler and
all accessories operate using 230 V AC electric current. Improper installation or repair can pose the danger of
life-threatening electric shock. Installation may be performed only by appropriately qualified technicians.
Caution symbols
Please take careful note of the following symbols in these Installation instructions.
1.2 Flue
A properly dimensioned flue is required for optimal functioning of the combustion system. Measurement of the
dimensions must follow EN 13384-1. See the Technical data section for values required for this calculation.
Please note that in the permissible performance range, flue gases may be below 160°C.
The flue gas system must display at least the following classification:
Temperature class:
T400 = nominal operating temperature 400 °C
Soot fire resistance class:
G = flue gas system with soot fire resistance
Corrosion resistance class:
2 = suitable for unprocessed wood fuels
We would recommend fitting an energy-saving intake regulator for problem-free operation. This will largely
prevent moisture in the flue, and losses resulting from down-time will be reduced (draught interruptions). If you
have a feed pressure (flue draught) of more than 0.20 mbar, the energy-saving intake regulator must be fitted.
Note!
We would recommend fitting the draught limiter outside the flue around ½ m below where the ex-
haust pipe intersects with the flue.
Attention!
Ignoring the warnings identified can lead to personal injury.
Information!
Ignoring the warnings identified can lead to malfunction of, or damage to the boiler or heating sys-
tem.

for operation.
Information!
Frequently, overhaul of existing systems involves oversized flue cross-sections or flues not desig-
ned for lowtemperature operation. We suggest an evaluation by the local building inspector before
installing the boiler system. In this way appropriate modifications can be made to the flue before
system installation (see technical data for flue calculation values).
