  • Page 4: Instructions Prior To Installation

    Instructions pertaining to the user Instructions prior to installation This boiler is designed to heat water at a lower than boiling temperature at atmospheric pressure. The boiler must be connected to a central heating system and to a domestic hot water supply system in compliance with its performances and output power.

  • Page 5: Room Temperature Adjustment

    Figure 1 0209_3024 Warning: During initial lighting, until the air contained in the gas pipes is not released, the burner may fail to light immediately and that may cause a ‘blockage’ of the boiler. In this case we recommend you repeat the ignition procedure until gas is delivered to the burner, setting selector (1) to ( ) for at least 1 second (see also figure 4).

  • Page 6: Filling The Boiler

    Filling the boiler Important: Regularly check that the pressure displayed by the pressure gauge (7) is 0.5 to 1 bar, with boiler not operating. In case of overpressure, open the boiler drain valve. In case the pressure is lower open the boiler filling tap (figure 3). We recommend you open the tap very slowly in order to let off the air.

Separated horizontal flue terminals installation options IMPORTANT: Ensure a minimum downward slope of 1 cm toward the outside per each metre of duct length In the event of installation of the condensate collection kit, the angle of the drain duct must be directed towards the boiler.
  • Page 15 Separated vertical flue terminals installation options L max = 15 m L max = 14 m Important: if fitting a single exhaust flue duct, ensure it is adequately insulated (e.g.: with glass wool) wherever the duct passes through building walls. For detailed instructions concerning the installation of fittings refer to the technical data accompanying the fittings.
