6.1 Fitting the hot and cold water connection
>
Make the domestic hot and cold water connections as
shown.
>
Ensure correct water pressure and flow requirements
and that any expansion can be accommodated with the
cold supply pipe work (

section
2.5.7

Low loss header
A low loss header disconnects the boiler from the heating
system. The system is no longer dependent on the remain-
ing feed head of the boiler. In conjunction with the heating
pump, the low loss header ensures that a sufficiently high
minimum quantity of water is always circulating through
the boiler. No electrical accessories are required in order to
use a low loss header.

Connecting the condensate discharge
pipework
a
Danger!
Risk of death from flue gases!
An empty or insufficiently filled condensate
trap may allow flue gas to escape into the
room air.
>
Make sure that the condensate trap is
filled with water when switching on the
boiler.
a
Danger!
Risk of death from flue gases!
If the condensate discharge pipework is
connected tightly to a fixed connection to
the waste water piping, the internal conden-
sate trap can be drained fully.
>
Do not connect the condensate discharge
pipework tightly to the waste water
piping.
ecoTEC pro boilers are equipped with a condensate trap
that continually deposits the contents to the discharge pipe.
