„ Important recommendations for connecting the
boiler to the heating circuit

Between the boiler and the safety valves there must be no
complete or partial closing device.
France: DTU - 65.11, § 4.22 - NF P 52-203

Heating installations must be designed and implemented
to prevent heating circuit water and products contained in
it returning to the drinking water system (article 16-7
Departmental Health Regulations). A CB disconnector
(area disconnector for different uncontrollable
pressures)must be installed for filling the heating circuit
according to the NF P 43-011 standard.
Before connecting the heating circuit hydraulic connections, it is
essential to rinse the heating circuits to remove any particles which
might damage certain components (safety valve, pumps, valves...).
In the event where the burner is located at the highest point in the
installation, a dry running or water pressure control device my be
fitted.
4.4.2 Hydraulic connection of the heating circuit
1. Heating flow
2. Heating return
3. Drain cock (connection for 14 mm interior diameter pipe)

Insulate the heating flow and return pipes only outside the
casing.

The drainage device can be connected with a flexible hose.
