Instructions for the installer
9. FINAL OPERATIONS FOR GAS APPLIANCES
After making the adjustments described above, reassemble the appliance by following the instructions in point 7.1 Replacing nozzles in reverse order.
9.1 Adjusting the minimum for town and natural gas
Light the burner and turn it to the minimum position. Extract the gas tap knob and turn the adjustment screw inside or next to the tap rod (depending on the model) until the correct minimum flame is achieved. Refit the knob and verify that the burner flame is stable (turning the knob rapidly from the maximum to the minimum position the flame must not go out). Repeat the operation on all the gas taps.
9.2 Adjusting the minimum for liquid gas
To adjust the minimum with liquid gas, you must tighten the screw inside or next to the tap rod (depending on the model) fully in a clockwise direction. The bypass diameters for each individual burner are shown in the table 8.1 Burner, nozzle and gas consumption characteristics.
9.3 Lubrication of gas taps
Over time the gas taps may become difficult to turn and get blocked. Clean them internally and replace the lubrication grease. This operation must be carried out by a specialised technician.
