ADJUSTING THE AIR PRESSURE SWITCH
The air pressure switch must be adjusted so that an insufficient air flow does not allow
the CO value to exceed 1% in volume. After having adjusted the gas flow and obtained
optimum combustion (CO
pressure switch must be adjusted. Remove the cover with the burner operating, cover
the air intake progressively with a piece of cardboard to obtain a value of CO
(G20-G25)> 13 (G30-G31) and a CO value of less than 5,000 ppm. Adjust the air
pressure switch until the burner shuts down. Remove the cardboard from the air intake
and start up the burner again. Replace the cover.
ADJUSTING THE GAS PRESSURE SWITCH
Adjust the pressure switch to 50% of the rated pressure of the gas used.
