Measuring The Ionisation Current; Checking The Air And Gas Pressure On The Combustion Head - Riello RS 310/E BLU Installation, Use And Maintenance Instructions

7.2.5

Measuring the ionisation current

The burner is fitted with an ionisation system to check that a
flame is present.
The minimum current for control box operation is 4 µA. The oper-
ator panel displays "30%" (see "List of parameters" on page 45,
parameter no. 954).
The burner provides a much higher current, so controls are not
normally required.
However, if it is necessary to measure the ionisation current, dis-
connect the plug-socket on the ionisation probe cable and insert
a direct current microammeter with a base scale of 100 µA, as
shown in Fig. 36.
Carefully check the polarities!

7.2.6 Checking the air and gas pressure on the
combustion head
To carry out this operation it is necessary to use a pressure gauge
to measure the air and gas pressure at the combustion head, as
shown in Fig. 37.
