Pict.11 – Burner and gas valve view (example from LPP / MPP)
Primary air plate
In the burner there is a primary air plate assembled between the gas manifold with
injectors and the burner itself in order to ensure the correct mixture of air and gas
according to the specific appliance model.
The plate has indexation pins that ensure the correct assembly on the heat cell and must
be always replaced together with the injectors in gas conversion.
