for boilers with integrated pump

By means of the conversion kit (item no. 3143 / 34431 / 37431), the modular distribution

manifolds get a bypass which connects the flow and return line without causing any

resistance (low-loss header).

It must be considered that the pump of the boiler circuit must deliver a higher flow rate

than the consumer pumps need in total. Otherwise, unwanted circulations occur on the

right or left end of the low-loss header. In that case a hydraulic separator must be

installed below a distribution manifold.

For all low-loss headers, please note:

When you plan the system you must already check whether a low-loss header can be

used. In combination with central heating boilers, hydraulic separators must be installed

below / upstream of a distribution manifold as the boiler delivers a flow rate with a high

temperature difference (leads to unwanted circulation in low-loss headers).
