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:
Type E165A Model M-. MD. SR. *. A. 1. 80. ES

BLAST TUBE AND AIR INLET CONFIGURATION
(see the figure on page 5)
SR = Standard blast tube + ABS polymer (silenced) air intake
SP = Standard blast tube + aluminium air intake
LR = Extended blast tube + ABS polymer (silenced) air intake
LP = Extended blast tube + aluminium air intake

0 = 2 gas valves
1 = 2 gas valves + gas proving system
7 = 2 gas valves + maximum gas pressure switch
8 = 2 gas valves + gas proving system + maximum gas pressure switch

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.
