Gas connection

Only certified components must be used for the gas line connections.
A hose is supplied as standard having an inner diameter of 6 mm and an outer diameter of 8 mm, including ¾"G
swivel fittings.
The generator is complete with:
• a double gas valve;
• a gas filter.
It is mandatory to use an EN126-certified large capacity gas filter with filtration level inferior or equal to
50 micron, without pressure stabilizer, because the filter installed as standard upline of the gas valve
has a small surface.
For correct maintenance, the connection to the hot air generator must be implemented using an o-ring
gasket.
Do not put threaded fittings on the gas fitting directly.
The figure shows the diagram to reference for the connection.
The components involved are:
1 main burner;
2 gas solenoid valve in main burner;
3 pressure stabilizer;
4 safety gas solenoid valve;
5 small-section gas filter;
6 vibration dampening joint;
7 large-section gas filter;
8 gas valve;
9 pilot burner;
10 gas solenoid valve in pilot burner.

BI = components under the responsibility of the installer
Under no circumstances should the gas circuit be supplied at pressures exceeding 60 mbar.
The risk is that the valve may break.
