With reference to Section 7.2 the connection M
(Fig. 15, page 16) must be sealed off with a 3/4" cap if
no controller is used.

USER NOTE
The vent pipes must be installed in a way
that the condensate can freely drain from the
flue pipe into the boiler.
If that is not possible, install drain-tees in the
vent pipe to drain away the condensate. Use
only stainless steel or plastic parts.
USER NOTE
The return connection RK1 (Fig. 1, page 6)
must always be used. The heating circuit
with the lowest temperature must be con-
nected to RK1. Circuits running at higher
temperatures should be connected to return
connection RK2.
If the second return connection RK2 is not
used, is is imperative that it is capped.
