NOTICE
▶ To prevent contamination in the heating system we
recommend you integrate a dirt filter ( fig. 13,
[10]) in the return pipe, near the boiler. In an old
system it is a requirement to install a dirt filter. Also
install shutoff valves to enable filter cleaning
immediately upstream and downstream of the dirt
filter (scale cartridge or y-strainer)
▶ Connect the supply pipe with a flat rubber seal installed to the Supply
connection ( fig. 13, [1]) making sure it is not under stress. Use a
supply pipe with a minimum diameter of 1½" (38 mm).
▶ Connect the return pipe with a flat rubber seal installed to the Return
connection ( fig. 13, [2]) making sure it is not under stress. Use a
return pipe with a minimum diameter of 1½" (38 mm).
6.4.5
Installing the pump
Always use the supplied Buderus pump group and the low loss header
when installing a single boiler so correct flows are guaranteed. It is not
necessary to install a low loss header for cascade systems.
▶ Install the pump ( fig. 13, [8]) in the return circuit ( fig. 13,
[2]).
6.4.6
Installing the condensate trap
WARNING:
Danger of fatal accident due to poisoning
▶ If the condensate trap is not filled with water, flue gas
can escape and put people's lives at risk.
▶ Fill the condensate trap (supplied with the boiler) with water
( fig. 14).
