Please observe the following information regarding the boiler
connection to the system side. These instructions are important for
trouble-free operation.

The weld neck flange and flat gasket are shown (
Fig. 28, [4 and 5]).

Installing draft diverter, baffles and burner door
Next step in the assembly process is to install the burner door and draft
diverter. The pre-assembled boiler comes with these components
already installed.
7.8.1
Positioning the draft diverter
The GP sealant rope (fiberglass cord with silicon casing) which forms a
seal is inserted in the draft diverter at the factory.
▶ Place the draft diverter onto the four threaded studs on the rear
section (
Fig. 29 [1 to 4]) and secure using washers and nuts.

NOTICE:
Risk of system damage from leaking
connections.
▶ All pipe connections to the boiler must be free of
stress and tension.
NOTICE:
System damage from deposits, local
overheating, and corrosion.
▶ As a basic rule, clean and flush existing systems
thoroughly before connecting the new boiler.
▶ Install a desludging unit in the boiler return to
prevent damage to the boiler.
The boiler supply and return manifolds are included in
the Buderus scope of delivery.
NOTICE:
Risk of system damage from temperature
stresses.
▶ Install a fill valve on the system side.
▶ When the heating system is in operation, do not fill it
via the boiler fill & drain valve. Instead, use the fill
valve on the system side.
