Air-gas circuit.

The circuit consists of a total pre-mix combustion system

comprising a fan (7), a pneumatic type gas valve (9), a Venturi

pipe (5) and a special cylindrical burner (4) that works inside
the condensation module.

Operation.

The fan (7) is controlled by the microprocessor driven p.c.b.

that varies speed according to the output required.

By means of this fan, combustion air is taken from the draught

diverter (3), which is in contact with outside and sent through

a duct where a Venturi pipe (5) is installed.

A positive pressure signal (P1) is located at the Venturi (5) inlet

and varies in a way directly proportional to the quantity of air

extracted by the fan (7) and which is detected by means of a

pressure point connected to the pneumatic gas valve (9).

The energising of the main valve coils causes both internal

shutters to open and the gas to flow through, whose outlet

pressure is regulated by the same pneumatic valve with a 1:1

ratio at pressure “P1”.

Through nozzle (6), gas is injected at the inlet of the Venturi

pipe (5) where pre-mixing begins with the combustion air.

The resulting mix is ignited on the cylindrical burner surface

(4) by a spark of the ignition electrodes (10).

Gas valve.

The gas valve features two main coils controlled by the inte-

grated board and a pneumatic control unit that modulates the

exiting gas pressure at a 1:1 ratio at pressure (P1) detected at

the Venturi pipe inlet.

The ratio between air and gas pressures (off-set) are set on this

valve

(see gas regulations).

Electrical coils (4).

Two ON-OFF type coils that are powered by the integrated

board (24 V DC) when the burner has to be ignited.

They are connected in series and energised at a voltage of 24

V through a connector (3).

Pneumatic unit (2).

Outlet pressure can be varied with this unit at a 1:1 ratio at

pressure (P1) detected at the Venturi pipe inlet which is re-

turned to the valve through a silicone pipe (1).

Thanks to this system, the percentages in the air-gas mix remain

constant at optimum values on the entire modulation field thus

ensuring an almost constant combustion performance.

By means the off-set screw (2) the air-gas ratio can be adju-

sted.

This is only necessary if,

after having analysed the flue,

incorrect combustion values are found

(see air-gas ratio ad-

justment).
