Safety valve connections
Condensate connection
7. Installation
Note :
The connection of a safety valve is compulsory in order to conform
to the pressurised equipment directive (DESP).
The valve must be CE certified in category IV.
Its size must vary according to the characteristics of the boiler, to
the volume of the pipes upstream of the valve and the volume of the
appliance to be protected.
The drainage connector of the safety valve must absolutely be
connected to the outside of the building and out of reach of human
interference (on the roof for example).
In the event of excess pressure, the exhaust outlet from the valve
can be dangerous due to the pressure and high temperature of the
steam.
Note :
After around 10 metres, the pressure loss in the condensate return
pipes is too great.
It is therefore necessary to calculate its diameter according to
the length of the pipes from the bleeders up to the receiver tank,
compared to the admissible pressure = 300 kPa maxi (3 bar).
