The GN4 N range of cast iron sectional boilers are available in 8 sizes from 200-650 kW and are suitable for use with forced gas, pressure jet oil (28 or 35 sec) or duel fuel with the option of On/Off, High/Low or Fully Modulating burners. For ease of handling on site all models are delivered unassembled. FERROLI can if required arrange for site assembly. The
unique 3 pass flueway ensures maximum heat transfer and subsequent high operating efficiencies. GN4 N boilers are designed for use with fully pumped indirect heating systems up to a maximum working pressure of 4 bar and a flow temperature of 85°C. The Pre-wired Control Panel incorporates On/Off mains power switch, combined High/Low thermostat, High limit safety thermostat - manual reset and thermometer. A choice of flow and return tapping configuration is available to suit the system application. The installation of electrical and associated controls should be installed so that the burner is never allowed to fire when there is no demand for heat. Provision should also be made to dissipate residual heat on plant shut down with the fitting of a pump over-run device. The GN4 N is CE approved and conforms to all the relevant European Standards.
