Burner model identification
Burners are identified by burner type and model. Burner model identification is described as follows.
Fuel
The burner technical specifications, described in this manual, refer to natural gas (calorific net value Hi = 9,45 kWh/Stm
3
, density
ρ
=
0,717 Kg/Stm
3
). For different fuel such as LPG, town gas and biogas, multiply the values of flow and pressure by th corrective factors
shown in the table below.
For example, to obtain the flow and pressure values for the biogas:

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.
