• Make sure that the ambient thermostat is in
the position “call for heat”.
• Withdraw an abundant amount of dhw by
opening the cocks.
• Compare the value of CO2 read on the flue
gas analyser with the one in the "Data in
d.h.w. mode" table and the values of CO2 at
Q.min. "Technical data" section page 24
(model M160.2025 SM/M) and page 27
(model M160.3035 SM/M).
• To calibrate the boiler CO2 (gas pressure at
the burner) completely unscrew the protective brass cap B and turn the underlying ø 4
mm Allen screw Figure 7.5, turning it clockwise increases the CO2.
Check maximum burner pressure
• Press key 17 3 times until the LCD display
indicates the letters dP (chimney sweep active in maximum dhw mode) that alternate
with the value of the heating water temperature (e.g.60), indicating the activation of the
"chimney sweep function" at maximum output in dhw mode (Figure 7.6).

• Compare the CO2 value read on the flue gas
analyser with CO2 at Q.nom. in dhw operation specified in the "Technical data" section
in the "Data in d.h.w. mode" table on page
