Connecting the boiler
This chapter will explain how to make
all connections to the boiler with regard
to:
Hydraulic connections (1, 3)
Condensate drain connection (7)
Gas connection (6)
Flue gas connection (5)
Air intake connection (only when
using roomsealed, order seperately)
(2)
Electrical connection (4)
The boiler should always be connected
in such a way, that the system applies
to all relevant standards and regulati-
ons (European, national and local). It's
the responsibility of the installer to en-
sure that all standards and regulations
are respected.
Hydraulic connections
The boiler should always be connected
in such a way, that water flow through
the boiler can be ensured at all times.
Connect the flow (3) and return (1) con-
nection of the system tension free to
the boiler connections. If the boiler is
used in a system with two return cir-
cuits (only R3600SB series), the
common return becomes the low
temperature return, the 2nd return con-
nection is the high temperature return
(remove cap/flange before connecting).
Condensate connection (7)
After filling with water, the syphon
(included in delivery) should be in-
stalled to the connection at the bottom
of the condensate receptacle. The con-
nection to the draining system should
always be done with an open connec-
tion, in order to avoid a flooding of the
boiler in case of a blocked drain.
