4.2 Minimum flow in the heating system
Make sure that the dimensioning of the piping in the heating system is sufficient to get the minimum flow presented below:
HP Size 6kW 9kW 11kW 13kW 16kW 18kW
l/min 7.9 11.5 14.5 16.7 19.8 23.7
Insufficient flow in the system may result in high pressure-, or low heat circulation flow alarms.
4.3 Safety valves
Warning Radiator systems with a closed expansion tank must also be equipped with an approved manometer and
safety valve, minimum DN 20, 1.5 bar opening pressure, or according to country specific requirements.
Warning Cold and hot water pipes and overflow pipes from safety valves must be made of heat resistant and corro-
sion-resistant material, e.g. copper. The safety valve overflow pipes must have an open connection to the
drain and visibly flow into this in a frost-free environment.
Warning The connecting pipe between the expansion tank and the safety valve must slope continuously upwards. A
continuous upwards slope means that the pipe must not slope downwards from the horizontal at any point.
4.4 Connection heating and hot water
4.4.1 Connect cold and hot water lines
1. Connect the cold water and hot water pipes with all the necessary components according to the connection diagram for the rele-
vant system.
4.4.2
Connect the heating system supply and return lines
For information on how flexible hoses should be installed, see Flexible hoses.
1. Connect the supply pipe with a flexible hose connection and with all the necessary components.
2. Connect the return pipe with a flexible hose connection and with all the necessary components including a filter.
3. Insulate the supply and return lines.
