GAS GOVERNOR ADJUSTMENT
The gas governor, with built-in filter, must be installed so as to stabilise the outlet gas pres-
sure and to avoid that eventual impurities reach the gas valve. To increase gas pressure,
remove the cover of governor and turn screw C. Unscrew screw C to reduce pressure, then
fit the cover.
Note: the inlet gas pressure must not be higher than the specified max. gas pressure.
To calculate the burner's working output, in kW, proceed as follows:
- Check at the meter the quantity of supplied litres and the duration, in seconds, of the rea-
ding, then calculate the burner's output through the following formula:
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
than 75 ppm), the air 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
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.
