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.
