ASSEMBLY

4.3.3  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. 

4.3.4  Minimum flow rate

During the burner operation a circulation pump must al-

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

ted in the technical data must always be provided.

4.3.5  To be provided by customer

A pressure expansion tank adapted to heating system, 

water volume and static height.

4.3.6  Examples of hydraulic interconnection

Gas boiler with

 

- Free-standing calorifier 

 

- 1 direct circuit

- 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  re-

gulations. With underfloor heating, a flow temperature 

monitor must be installed.

 

- Shut-off  devices  to  the  safety  equipment  (pressure 

expansion  tank,  safety  valve,  etc.)  must  be  secured 

against  unintentional  closing!  Install  sacks  to  prevent 

single-pipe gravity circulation!
