6.2 Connecting the manifold to the boiler/heating source
• The supply pipe of the boiler must be connected to the supply valve of the manifold.
• The return pipe of the boiler must be connected to the return valve of the manifold.
Thesupplyandreturnpipingmusthavesufcientcapacity;itappliesingeneralthat:
1. manifolds 1 to 4 groups: minimum diameter of 15 mm with maximum 6 metres of supply and return
pipingfromtheheatsource(ifyouuseamulti-layerpipe:20mm)
2. manifolds 5 to 10 groups: minimum diameter of 22 mm with maximum 14 metres of supply and return
pipingfromtheheatsource(ifyouuseamulti-layerpipe:25/26mm)
3. manifolds 11 to 15 groups: minimum diameter of 28 mm with maximum 16 metres of supply and
returnpipingfromtheheatsource(ifyouuseamulti-layerpipe:32mm)
PLEASE NOTE: If radiators are connected to the same supply and return pipe, account should be taken
ofwhetherthediameterofthepipeissufcient.
6.3Connectingtheunderoorheatingpipetothemanifoldwithintegrated
pump
Werecommendtolimitthemaximumlengthoftheunderoorheatingpipeto:
1. Approx. 100 metres per group on application of a 16 x 2 mm, 18 x 2 mm or 20 x 2 mm pipe.
2. Approx. 90 metres per group on application of a 14 x 2 mm pipe.
3. Approx. 65 metres per group on application of a 10 x 2 mm or 12 x 2 mm pipe.
*thelengthofthepipingcandeviateforindustrialoors.Theaboverecommendationsonlyserveasa
guideline.
If several groups are used, we also recommend to put the pipes with the same length together as much
aspossible.Ifthepipesvarywidelyinlengthpergroup,werecommendtomountowmetersunderthe
groupvalves;see‘puttingintooperation/settingthemanifold’.
