Smeg SCB60MFX manual Final Operations, Regulation of the hob burner minimum level for natural gas

Instruction for the installer

4 FINAL OPERATIONS

After replacing the nozzles, reposition the flame-spreader crowns, the burner caps and the grids.

Following adjustment to a gas other than the preset one, replace the gas adjustment label fixed to the appliance with the one corresponding to the new gas. This label is in the packet together with the nozzles.

4.1Regulation of the hob burner minimum level for natural gas

Light the burner and turn it to the minimum position . Extract the gas tap knob and turn the adjustment screw at the side of the tap rod until the correct minimum flame is achieved.

Replace the knob and check burner flame stability: (rapidly turning the knob from maximum to minimum position, the flame should not go out). Repeat the operation on all the gas taps.

For models with valves, keep the knob at minimum level for about 1 minute to keep the flame lit and to activate the safety device.

4.2Regulation of the hob burner minimum level for LPG

For regulating the minimum with LPG, the screw at the side of the tap rod must be turned clockwise all the way.

The bypass diameters for each individual burner are shown in paragraph “3.2/3.3 Burner and nozzle characteristics table”. Once the regulation has been completed, replace the seal on the by-passes using paint or similar materials.

4.3Regulation of the oven burner minimum level

The oven thermostat is equipped with a by-pass to regulate the minimum level, which is visible underneath the thermostat knob.

When the gas type is changed, the by-pass should be regulated as follows:

1.Turn on the oven burner to maximum for 10/15 minutes with the door closed and without the floor. Turn the knob to the minimum temperature, remove the knob and regulate using a flat screwdriver.

2.For LPG turn the by-pass screw clockwise as far as it will go. The by-pass diameter is shown in the paragraph “3.2/3.3 Burner and nozzle characteristics table”.

3.For natural gas, regulate the by-pass so that turning the thermostat knob from minimum to maximum the flame remains stable and constant. Once the regulation has been completed, replace the seal on the by-pass using paint or similar materials. Close the oven door and make sure that the burner stays on minimum.

4.4Positioning and levelling of the appliance

Having carried out the electricity and gas hook-up, level the appliance using the four adjustable legs. For best cooking the appliance must be perfectly level.
