Fuel
The burner technical specifications, described in this manual, refer to natural gas (calorific net value Hi = 9.45 kWh/Stm

0.717 Kg/Stm ) and LPG (calorific net value Hi = 26.79 kWh/Stm
biogas, multiply the values of flow and pressure by th corrective factors shown in the table below.

ATTENTION! The combustion head type and the settings depend on the fuel. The burner must be used only for its
intended purpose specified in the burner data plate .
ATTENTION: the corrective factors in the above table depend on the gas composition, so on the calorifc value and
the density of the gas. The above value can be taken only as reference.
