2. Weld the flange heating water of the final-cooling loop to the weldment of the final-cooling loop (depending on the boiler-room layout);
insert a sealing Ø 90 x 60 x 3 between the flange and boiler; afterwards mount the weldment with help of 4 pcs of the nuts M 10 and 4 pcs
washers 10,5 to the boiler. Interconnect the upper output of heating water by a weld-joint with to the heating system.
Interconnect the bottom output from the final-cooling loop by means of welding of 1 1/2" tube with the return water output (return water
