2.2.4 Heating System Installation/Standards
ÖNORM/DIN EN 12828 governs the installation of the heating system:
Return feed lift
If the heated water return feed is under the minimum return temperature, a portion of the heated
water outfeed will be mixed in.
IMPORTANT
Operating without return feed lift!
Damage may result from dropping below the dew point or the formation of
condensation!
In combination with combustion residues, the condensation forms a caustic condensate which
shortens the service life of the boiler!
Take the following precautions:
A return feed lift is a regulatory requirement!
2.2.5 Chimney Connection / Chimney System
As per EN 303-5, the entire flue gas system is to be designed in such a way as to prevent
possible seepage damage, insufficient feed pressure, and condensation.
In relation to this, it’s necessary to point out that flue gas temperatures of less than 160 K above
room temperature can occur within the permitted operating range of the boiler.
The flue gas temperatures in the cleaned state as well as additional flue gas values can be
found in the table “Boiler Data for Configuring the Chimney” in the assembly instructions.
Design information
Make a connection using the shortest path rising between 30 – 45° to the chimney and insulate
the connecting piece.
The entire flue gas system, the chimney and its connection, must be laid out as per
ÖNORM/DIN EN13384-1.
In addition, local and other lawful regulations apply!
The chimney must be approved by a smoke trap sweeper or chimney sweep!
As per TRVB H 118, an explosion flap must be installed in the flue gas pipe or in the
chimney!
Draught limiter
Recommended: Installing a draught limiter A
Attaching the draught limiter:
U Directly under the mouth of the flue gas line, since an under-
pressure condition can always be found there!

Fusing Properly fuse the control system and any electronic
components
When changing fuses, ensure the fuses are rated for
the rated current (10AT).
Devices for Preventing the Boiler from Over-heating
1. Thermal Discharge Safety Device
When 100 °C is reached, this device opens a valve and sends
cold water to the safety heat-exchanger in order to decrease
the temperature.
2. Safety Temperature Limiter
Switches off the blower fan at the maximum boiler temperature
of 105 °C. The pumps continue to run.
Once the temperature has fallen to under approx. 95 °C,
the safety temperature limiter 10 can be unlocked
mechanically.
3. Safety valve
Protection against over-heating:
When the boiler pressure reaches approximately 3 bar, the
safety valve opens and the heated water is blown off in the
form of hot water or steam.

Feed based on output
Only replenish the fuel if energy is needed!
If too much fuel is loaded:
´ The boiler drops below its minimum output limit and switches over to so-called low-
temperature operation (fan switches off)
During low-temperature operation, the efficiency drops, the emissions increase and the
boiler tars up (pitch formation!)
3.2.6 Switching off the system
IMPORTANT! Only switch off when the boiler has
cooled down.
Switch off the main switch 9 at the control system
´ The controller is switched off.
´ All the system components are powered down.

5.2 Internal boiler faults
When a fault has occurred and
has not yet been cleared:
- Status LED 7.6 or 8.5 blinks red
- A fault message is displayed on the
display
Internally, a distinction is made between a fault and a warning. A fault has the same effect as an
“EMERGENCY STOP” and shuts down the system immediately. A warning, on the other hand,
shuts down the system in a controlled manner.
Fault message list:
À See the operating instructions for the “Digitronic S 3100” or “Lambdatronic S 3100”
