Important initial information for the Technician
The following instructions are available for operation and installation:
Heating expert: Assembly/installation instructions, list of spare parts
System owner: Operating Manual, quick guide, heating instructions
1.1 Safety
The boiler and related accessories are state of the art and meet all applicable safety regulations.
1.2 Please note!
Your boiler and all accessories can be operated using 230 V AC electrical voltage. Improper installation or repair
can pose the danger of life-threatening electrical shock. Installation and repair may be performed only by appro-
priately qualified technicians.
Caution symbols
Please take careful note of the following symbols in these assembly instructions.
Ignoring the warnings identified can lead to
personal injury
.
Ignoring the warnings identified can lead to
malfunction of, or damage to the boiler or heating sys-
tem
.
The specified safety requirements are to be followed in accordance with nationally applicable regula-
tions, standards and guidelines.
1.3 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 (section 4.3) for values required for this calcu-
lation.
Please note that in the permissible performance range, flue gases may be below 160°C. A draught limiter is
needed if the maximum draught is exceeded during operation.
Note:
We would recommend fitting the draught limiter outside the flue around ½ m below where the exhaust
pipe intersects with the flue.
Frequently, overhaul of existing systems involves over-sized flue cross-sections or unsuitable flues.
We sug-
gest an evaluation by the local building inspector before installing the boiler system.
In this way appropri-
ate modifications can be made to the flue before system installation (see section 4.3 for flue calculation
values).
