Water Connections; Connecting The Burner; Electrical Connections; Flue Connections - Ferroli GN2 N Operating, Installation And Maintenance Instructions

2.1 Water connections

Make the water connections to the appliance according to the indications shown both next to each fitting and in Figure 2 of this booklet.
The connections must be made in such a way that the pipes are not under stress. The safety valve must be fitted in the central heating circuit,
as close as possible to the boiler, without there being any obstructions or on-off devices between the boiler and the valve.
The appliance is not supplied with an expansion vessel, and therefore such device must be connected by the installer. Please note that in this
regard, the pressure in the system, when cold, must be between 0.5 and 1 bar.

2.2 Connecting the burner

Oil or gas jet burners for pressurised furnaces can be used if their operating characteristics are suitable for the dimensions of the boiler's
furnace and its over-pressure value. The burner must be chosen following the instructions provided by the manufacturer, according to the field
of operation, fuel consumption and pressure, as well as the length of the combustion chamber.
Fit the burner following the instructions provided by the manufacturer of the device.

2.3 Electrical connections

The boiler should be connected to a single-phase, 230 Volt-50 Hz electrical line, using a permanent connection, installing a double
pole switch with contact openings of at least 3mm, and suitable fuses. Connect the burner and the room thermostat (if featured) as
shown in the wiring diagram in Chap. 4.
The electrical safety of the appliance is ensured only when the appliance is correctly connected to an effective earth system, as prescribed by
the safety standards in force. Have professionally qualified personnel check the efficiency and the rating of the earth system. The manufacturer
is not liable for any damage caused by the appliance not being correctly earthed. In addition, make sure that the electrical system is adequately
rated for the maximum power absorbed by the appliance, indicated on the rating plate, and in particular that the cross-section of the wires is
suitable for the power absorbed by the appliance.

2.4 Flue connections

The boiler should be connected to a suitable flue, manufactured in compliance with the standards in force. The pipe between boiler and the flue
must be made from material suitable for this purpose, that is, resistant to both high temperatures and corrosion. The joints should be carefully
sealed and the entire length of the pipe between the boiler and the flue should be thermally insulated, to avoid the formation of condensate.

2.5 Assembling the boiler

The boiler may be supplied:
1. As a set of elements, in 4 separate boxes, containing the Casing, Control panel, Elements, and accessories for assembling the elements.
Follow the instructions enclosed with the set of elements to assemble the boiler body. Follow the instructions below to assemble the casing
and control panel.
2. With the body already assembled, in 3 separate boxes containing the Casing, Control panel and Boiler body.
Follow the instructions below to assemble the casing and the control panel.
