Gas diaphragm (natural gas only)

For proper burner operation in the event of particular boiler-burner-chimney couplings, or with low back pressure

in the combustion chamber, you may want to install the gas diaphragm anyway inside the entire burner operating

range. Refer to the pressure/flow curves indicated below

Diaframma gas (solo gas naturale)

Nel caso di particolari accoppiamenti caldaia-bruciatore-camino, o nel caso di contropressioni basse in camera

di combustione, per un buon funzionamento del bruciatore, può essere conveniente montare il diframma gas in

qualsiasi caso, all’interno dell’intero campo di lavoro del bruciatore. Occorre fare riferimento alle curve di pressio-

ne / portata sotto indicate.
