combustion analysis button SW1
Wait for the burner to ignite.
The boiler will operate at maximum heating output and it will be possible to
regulate the combustion.
- Insert the analyser probes in the specific positions on the air distribution
box, after removing screw (
A
) and cap of the flue gases analysis socket (
B
).
- Perform the combustion check verifying that the
CO
2
values correspond
to those indicated in the multigas table.
-
Once checking completed,
remove the analyser probe and close the
combustion analysis sockets with appropriate caps and screw.
b
If the value displayed is different from the one shown in the
multigas table DO NOT OPERATE ANY ADJUSTMENT ON THE
GAS VALVE, please contact the Technical Assistance Centre.
b
The gas valve
DOES NOT REQUIRES ADJUSTMENTS
and the
possible tampering causes a malfunction or failure of the boiler.
b
When the combustion analysis function is in progress all the heat
requests are inhibited and a scrolling message appears at the foot of
the main page of the REC10;
green and red LEDs are off
.
