Appendix - Riello RL 22 BLU Installation, Use And Maintenance Instructions

NOTE
• The burner is factory set for two-stage operation and it must therefore be connected to the TR remove control device to command light oil
valve VH/L.
Alternatively, if single stage operation is required, instead of control device TR install a jumper lead between terminals T6 and T8 of connector
X4.
• The burners have been type- approved for intermittent operation. This means they should compulsorily be stopped at least once every 24
hours to enable the control box to perform checks of its own efficiency at start-up. Burner halts are normally provided for automatically by the
boiler load control system.
.
ATTENTION:
- Do not invert the neutral with the phase wire in the electricity supply line. Any inversion would cause a lockout due
to firing failure.
- Only use original spare parts to replace the components.
