Matching the burner to the boiler
The burners described in this manual have been tested with combustion chambers that comply with EN676 regulation and whose
dimensions are described in the diagram . In case the burner must be coupled with boilers with a combustion chamber smaller in dia-
meter or shorter than those described in the diagram, please contact the supplier, to verify that a correct matching is possible, with res-
pect of the application involved. To correctly match the burner to the boiler verify the necessary input and the pressure in combustion
chamber are included in the burner performance curve; otherwise the choice of the burner must be revised consulting the burner manu-
facturer. To choose the blast tube lenght follow the instructions of the boiler manufacturer. In absence of these consider the following:
z
Cast-iron boilers, three pass flue boilers (with the first pass in the rear part): the blast tube must protrude no more than 100 mm into
the combustion chamber.
z
Pressurised boilers with flame reversal: in this case the blast tube must penetrate at least 50 - 100 mm into combustion chamber in
respect to the tube bundle plate.
The length of the blast tubes does not always allow this requirement to be met, and thus it may be necessary to use a suitably-sized
spacer to move the burner backwards or to design a blast tube tha suites the utilisation (please, contact the manifacturer).
Burner ignitor
Execute the burner ignitor connections as follows:
Legenda
1 Gas valve
2 Gas filter
3 Manual cutoff valve
4 Pressure reducer
5 Tank
Gas supply:
LPG
Gas pressure:
100 mbar
Once the gas train in installed, execute the electrical connections for all its items (gas valves group, pressure switch).
ATTENTION:
once the gas train is mounted according to the diagram on picture above, the gas proving test mus be perfor-
med, according to the procedure set by the laws in force.
