1.
Make the water connections
(1)
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.

Connecting the condensate discharge pipe
Danger!
Risk of death from escaping flue gases!
The condensate siphon's condensate dis-
charge pipe must not be connected to waste-
water pipework because, otherwise, the in-
ternal condensate siphon may be drained
fully and flue gas may escape.
▶
Do not connect the condensate discharge
pipe tightly to the waste-water pipework.

The product is equipped with a condensate siphon
(1)
. (The
filling height is 145 mm). The condensate siphon collects the
condensate that has formed in a vessel with a volumetric ca-
pacity of approx. 200 ml and allows the contents to intermit-
tently drain into the drain pipe. This minimises the risk of the
