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
) and LPG (calorific net value Hi = 26.79 kWh/Stm
3
, density ρ = 2.151 Kg/Stm
3
). For different fuel such as 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.
