MONTAGE

4.4.3 Gravity brake

It is recommended to install a gravity brake, to avoid heat

losses due to gravity circulation (particularly important

when changing existing, open installations). The gravity

brake is necessary for summer operation with indirectly

heated storage water heater.

4.4.4 Minimum flow rate

During the burner operation a circulation pump must al-

ways be in operation too. The minimum flow rate indicat-

ed in the technical data must always be provided.

4.4.5 To be provided by customer

A pressure expansion tank adapted to heating system,

wa ter volume and static height.

4.4.6 Examples of hydraulic interconnection

Gas boiler with

-

Free-standing calorifier

- 1 direct circuit

Hydraulic schematic BDDE020

Fig. 04

RS-OT Room station (OpenTherm)

B1

Flow temperature monitor (if required)

BA

Outdoor sensor

BW

Calorifier sensor

Y7

Switching valve

SLP

Solar circuit pump

M5

Boiler circuit pump

- The example schematics merely show the basic prin-

ciple and do not contain all information required for

installation. Installation must be carried out according

to the conditions on site, dimensioning and local regu

-

lations.

-

With underfloor heating, a flow temperature monitor

must be installed.

- Shut-off devices to the safety equipment (pressure

ex pansion tank, safety valve, etc.) must be secured

against unintentional closing!

- Install sacks to prevent single-pipe gravity circulation!
