TYPE OF FUEL

Use category I3B/P gas only.

CONNECTION AND REPLACEMENT OF THE GAS CYLINDER

The gas cylinder must be replaced in the open air, away from heat sources, in an atmosphere without flames.
Only the following accessories must be used for connection of the gas cylinder to the heater:

• Liquid gas flexible pipe.
• Liquid gas pressure regulator complete with safety valve.
  CHECK THE INTEGRITY OF THE GAS SUPPLY PIPE. IF THE GAS HOSE MUST BE REPLACED, ONLY USE THE FLEXIBLE TYPE SUITABLE FOR THE

PRESSURE USED, REFERRING TO NATIONAL REGULATIONS.

• To connect the heater to the gas cylinder:
  ATTENTION: ALL THREADING IS SINISTRAL, I.E. THEY ARE TIGHTENED IN AN ANTI- CLOCKWISE DIRECTION.

  • Screw the gas hose to the heater fitting (Pic. 4).
  • Install the pressure regulator on the gas cylinder. Make sure there is a gasket present on the regulator (if envisioned by the type of connection) (Pic. 5).
  • Connect the gas hose to the pressure regulator (Pic. 6).
  • Open the gas cylinder cock (Pic. 7).
  • .Press the regulator release button (Pic. 8).
    Check tightness of fittings using soapy water: bubbles indicate a gas leak (Pic. 9). Several gas cylinders can be fitted together to obtain greater autonomy. The use of 30 kg gas cylinders is recommended, up to heating capacity of 33 kW. Over the power of 33 kW use gas cylinders with greater capacity. The use of gas cylinders with suitable capacity is recommended in order to prevent problems due to lack of gasification of the fuel. The correct functioning pressure (see data plate applied to the heater) is given by the regulator supplied or an equivalent model.

CONNECTION TO THE MAINS ELECTRICITY

CHECK YOUR ELECTRIC SYSTEM IS EARTHED CORRECTLY.
Before connecting the heater to the mains electricity, make sure that the power supply voltage and frequency are correct (see data plate applied to the heater). The connection to the mains electricity (Pic. 10)
