Flame Presence Check; Safety Components - Riello RLS 160/M MX Installation, Use And Maintenance Instructions

Fan
Check to make sure that no dust has accumulated inside the fan
or on its impellers, as this condition will cause a reduction in the
air flow rate and provoke polluting combustion.
Servomotor
Release cam 4)(Fig. 38 on page 32) from the servomotor, by
pressing and shifting button 3)(Fig. 39 on page 33) to the right.
Manually rotate it backwards and forwards to make sure it moves
smoothly. Now engage the cam again by shifting the button
2)(Fig. 39 on page 33) to the left.
Boiler
Clean the boiler as indicated in its accompanying instructions in
order to maintain all the original combustion characteristics
intact, especially: the flue gas temperature and combustion
chamber pressure.
Flame inspection window
Clean the glass of the flame inspection window (Fig. 45).

Flame presence check

Check the level of the flame detection signal with the "Check
Mode" function from the flame control: LEDs from 2 to 6 indicate

See "LED indicator and special function" on page 41.
Check Mode
With burner flame on:
 hold the reset button on the flame control pressed for at
