General regulations for the gas supply
· Connection of the gas valve
assembly to the gas mains must be
carried out by a recognised
specialist.
· The cross-section of the gas cable
must be such that the prescribed
gas flow pressure at the gas valve
inlet is not undershot.
Burner start-up automatically implies

guarantee that the system conforms to
the current standards and regulations.

diagram is mandatory.
The power supply and the electrical
connections must comply with the
applicable standards.
The installer must hold a licence issued
