7.5
Checking the gas line for leak-tightness
▶
Check the entire gas line properly for leak-tightness.
7.6
Installing the hot and cold water connection
Validity:
Product with integrated hot water generation
1.
Make the water connections as shown in accordance
with the relevant standards.
2.
Ensure correct water pressure and flow requirements
and that any expansion can be accommodated with the
cold supply pipe work.
7.7
Connecting the domestic hot water cylinder
Validity:
Product with heating mode only
▶
When connecting the domestic hot water cylinder, follow
the Installation instructions for the domestic hot water
cylinder.
7.8
Connecting the heating flow and heating
return
▶
Make the heating connections as shown in accordance
with the relevant standards.
7.9
Installing the drain pipe on the expansion
relief valve
1.
Install the drain pipe for the expansion relief valve so
that it does not interfere with the removal and fitting of
the lower section of the condensate trap.
2.
Install the drain pipe as shown (do not shorten).
3.
Make sure that the end of the pipe is visible.
4.
Ensure that discharged water or steam cannot cause
injury to persons or damage to electronic components.
5.
Ensure the discharge pipe work is installed, routed and
terminated correctly to minimise the risk of freezing up.

Connecting the condensate discharge pipe
Danger!
Risk of death from escaping flue gases!
The condensate drain pipework for the si-
phon must not be connected tightly to waste-
water piping because, otherwise, the internal
condensate trap may be drained fully and flue
gas may escape.
▶
Do not connect the condensate drain
pipework tightly to the waste-water pip-
ing.

The product is equipped with a condensate trap
(2)
. The
condensate trap collects the condensate that has formed in
a vessel with a volumetric capacity of approximately 200 ml,
and intermittently releases the contents into the drain pipe.
This minimises the risk of the drain pipe freezing.

Follow the instructions listed here and observe directives
and local regulations on condensate discharge.
