Establishing Water Connections - Vaillant ecoVIT exclusiv Installation And Maintenance Instructions Manual

5 Installation
▶
Install a gas stopcock with fire protection device in the
gas pipe, upstream from the product, at an easily access-
ible location.
▶
Purge the gas pipe before start-up.
5.6.2 Checking the gas line for leak-tightness
▶
Check the entire gas line properly for leak-tightness.
5.7

Establishing water connections

▶
Install the connections in accordance with the relevant
standards and the generally recognised rules of good
engineering practice.
5.7.1 Connecting the heating flow and heating
return
1. Between the heating installation and the product, install
the required safety devices and isolators that are to
be set on-site, along with a filling/draining cock in the
return.
2. Connect the heating flow to the heating flow connection
(1).
3. Connect the heating return to the heating return con-
nection (3).
4. If you do not connect a domestic hot water cylinder, use

Danger!
Risk of death from escaping flue gases!
The siphon's condensate discharge pipe
must not be connected to waste-water pipe-
work or a tundish because, otherwise, the
internal condensate siphon may be drained
fully and flue gas may escape.
▶
Do not connect the condensate drain
pipework tightly to the waste-water pip-
ing.
▶
Route the condensate discharge pipe to a tundish or to a
floor drain at the installation site.
▶
Route the condensate discharge pipe from the product's
condensate discharge with a downward gradient and
without any kinks. Otherwise, the condensate in the si-
phon increases and leads to a fault.
▶
Check whether the condensate has been discharged
correctly.
