*Note: These burners may not be used on Biasi equipment in Canada
Note: Consult burner manufacturers literature for gas manifold diagram and controls.
To determine how much gas is coming into the burner, or to set the gas meter correctly, the following formula can be used.
Ft3/hr = [3600/(sec. Per rev.)]*(Size of gas meter)
The chart to the right can be used to determine the flow rate depending upon the time per revolution and the size of the gas meter dial.
