SAFETY DEVICES
27
Chapter 8
The temperature safety sensors must be in place on the machine at a distance no greater than 30 cm from
the ow connection.
Whenever the generators lack a device, those missing can be installed on the thermo product ow pipe,
within a distance no greater than 1m from the machine.
Domestic type heating appliances with automatic feed must have a fuel block thermostat or a cooling
circuit prepared by the manufacturer of the appliance, activated by a thermal safety valve such as to
guarantee that the limit temperature set by the Standard is not exceeded. Connection between the power
supply unit and the valve must be free from interceptions. The pressure upstream from the cooling circuit
must be at least 1.5 bar.
MOUNTING OF HEAT DISCHARGE VALVE NOT SUPPLIED
The solid fuel heat generators must be installed with safety devices determined by laws in force. With this
purpose the TP30 boiler has a safety heat exchanger as well as the block thermostat.
The safety exchanger must be connected on one side to the water network (A) and the other to
the drainage network (C). The heat discharge valve, whose bulb will be connected to attachment B, on
reaching the safety temperature enables the inlet of cold water into the copper coil contained in the
boiler, discharging the excess heat through the pipe C towards an appropriately installed drain.
