Water Connections; Electrical Connections - Ferroli GN4 N Instrucciones De Uso, Instalación Y Mantenimiento

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 cor-
rectly 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.

and is delivered from
the factory on a pallet,
remove the bolts 1 that
fasten it to the pallet and
position it for final instal-
lation. Then assemble
the various panels.
