Safety Components - Riello RS 200/M BLU Installation, Use And Maintenance Instructions

Flame inspection window
Clean the glass of the flame inspection window (Fig. 40).
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 presence check
Check the level of the flame detection signal with the "Check
mode" function from the flame control: the LEDs from 2 to 6
indicate the flame signal level, respectively. See "LED indicator
and special function" on page 38.
Check Mode
With burner flame on:
 hold the reset button on the flame control pressed for at
least 3 sec.;
 the button colour will change from green to yellow;
 each operating status signalling LED will be compared to
20% of the maximum brightness;
 press the reset button again (<0.5sec) to reset the standard
operation of the signalling LEDs.Boiler
Clean the boiler as indicated in its accompanying instructions in
order to maintain all the original combustion characteristics in-
tact, especially the flue gas temperature and combustion cham-
ber pressure.

Combustion
Carry out an analysis of the combustion flue gases.
Significant differences
measurements indicate the points where most care should be
exercised during maintenance.
If the combustion values measured before starting maintenance
do not comply with applicable Standards or do not indicate
efficient combustion, consult the table below or contact our
Technical Support Service to implement the necessary
adjustments.
