Safety Components; Opening The Burner; Closing The Burner - Riello RS 810/M BLU Installation, Use And Maintenance Instructions

Flame presence check
The burner is fitted with an ionisation system to check that a
flame is present. The minimum current for flame control operation
is 6 µA (Fig. 32).
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.
Carefully check the polarities!
D3097
Gas leaks
Make sure that there are no gas leaks on the pipes between the
gas meter and the burner.
Gas filter
Replace the gas filter when it is dirty.
Combustion
If the combustion values measured before starting maintenance
do not comply with applicable legislation or do not indicate effi-
cient combustion, consult the Tab. O or contact our Technical
Support Service to implement the necessary adjustments.
It is advisable to set the burner according to the type of gas used
and following the indications in Tab. O.
