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.
RARED PRESSURE:
The ignition flow rate is carefully adjusted. during test phase to 1/3 of the maximum flow rate (according to specifications).
Operations for eventual further adjustment must be carried out by skilled personnel authorized by ECOFLAM
BRUCIATORI.
Setting at full-load
Adjust gas/air ratio with screw V (fig.2).
- More CO2 in direction of higher scale values.
- Less CO2 in the direction of lower scale value.
