3.2.1
Important recommendations for connecting the boiler to the heating circuit
There must be no total or partial closing mechanism
between the boiler and the safety valves (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 making the water connections of the heating circuit and
domestic hot water tank heat exchanger, it is imperative to rinse the
circuits to remove any particles which might damage the components
(safety valve, pumps, valves, ...).
When using installations with thermostatic protection,
only safety valves marked "H" may be connected, and only
to the boiler outlet safety measurement tap; their drainage
capacity must correspond to the boiler's maximum
nominal useful output (Germany: DIN 4751 form 2).
