Page 22: Adjusting Air And Gas Flow Rates
C.I.B. UNIGAS - M03956CR Adjusting air and gas flow rates ATTENTION: before starting the burner up, be sure that the manual cutoff valves are open and check that the pres- sure upstream the gas train complies the value quoted on paragraph “Technical specifications”. Be sure that the mains switch is closed. - Page 23 C.I.B. UNIGAS - M03956CR P73A CAUTION: perform these adjustments once the burner is turned off and cooled. The burner is factory-set wih the adjusting plate holes fully open, and the combustion head at its MAX position, so it is fit to work at the maximum output.
- Page 24 C.I.B. UNIGAS - M03956CR - Multibloc MB-DLE: the valve is adjusted by means of the RP regulator after slackening the locking screw VB by a number of turns. By unscrewing the regulator RP the valve opens, screwing the valve closes. The pressure stabilizer is adjusted by operating the screw VS located under the cover C .
- Page 25 C.I.B. UNIGAS - M03956CR Double-stage burners drive the burner to the low flame stage by means of the TAB thermostat; 10 In order to change the gas flow rate slacken the nuts DB (Fig. 24) and adjust the opening angle of the gas butterfly valve by rotating the rod TG (clockwise rotation increases gas flow, anticlockwise rotation decreases it).
