Tighten the check nut “D”.
-
For the triple crown burner (Fig. 5), loosen the “V” screw securing the adjustment
bush “B” and set the bush to an H distance from the base, respecting the value
indicated in table 2. Tighten screw “V” again.
-
Having replaced the main nozzles of the burners and having adjusted the primary air,
seal the adjusted tools with varnish.
Reassemble all the components removed in reverse order and stick the new data on the
technical data plate.
N.B. Removing the rear panel of the appliance, all the re-assembly operations of the
burners can be simplified.
Minimum level adjustment
- Burner minimum levels are preset for methane gas (G20)
operation. If operating on liquid gas (G30/G31) proceed as follows: ignite the burner at
minimum position, and, using a screwdriver, fully tighten the by-pass adjustment screw at the
side of the shank of the relevant tap. Check if the flame remains stable and uniform – to help
you check, rapidly turn the tap knob from maximum to minimum position. When you have
finished adjusting the by-pass valve, seal it with red paint. Make sure you fit a plate with the
new installation data. After having set the by-pass screw, seal it with red varnish.
