Central Heating System (typical system designs)
&
The Vitodens 100 is designed for connection to sealed central heating water
systems.
&
A sealed system must only be filled by a competent person.
Filling the heating system see page 48. Do not fill up the whole system using
the internal filling loop (the internal filling loop is only for topping-up).
Combination boiler
Note
The boiler incorporates an internal bypass to ensure adequate water flow. Cer-
tain thermostatic radiator valve manufacturers may require that a bypass valve
is fitted in addition to the integral by pass. Specifications as to the individual
requirements should be sought prior to installation.
