Page 31: Gas Valve Adjustment
15. gas valve adjustment Carry out the following operations in the given sequence: 1) Calibration of the maximum heat output. Check that the CO measured on the flue, with the boiler operating at the maximum heat output, is the same as that shown in table 1. Otherwise, turn the regulation screw (V) on the gas valve. - Page 32 IMportant: In the case of conversion from natural gas to propane (LPG), the following operations must be performed before calibrating the gas valve as illustrated previously: • Replace the gas nozzle placed inside the gas valve (flow gas connection). To perform this operation it is necessary to remove the gas valve by undoing the inlet and outlet connections and unscrew the nozzle using round-nose pliers.
