  • Page 10: Boiler Characteristics

    3.Boiler Characteristics 3.1 The Sargon 18S / 24S / 30S are fan fl ued, wall-mounted system boilers that supplies heating and possibly domestic hot water via a storage cylinder. Being room sealed the boiler may be installed in any room without the need for purpose made ventilation. However, if the boiler is installed in a compartment it is recommended that the compartment is ventilated for cooling purposes.

  • Page 11: General Installation

    4. Operation 4.1 Using the operating switch the boiler can be set to operate either on domestic hot water only or domestic hot water and heating. Note: Domestic hot water demand draws preference over heating. During heating periods the boiler will automatically revert back to heating mode, after a draw off of hot water, but there will be a 45sec delay if the No.S3 dipswitch is set to the OFF position.
  • Page 12 5.2 The boiler is designed to operate on fully pumped, pressurised sealed systems operating at a maximum of 3bar pressure and maximum design fl ow temperature of 85°C. 5.3 The boiler’s integral expansion vessel is pre-charged to a pressure of 0.5 bar and will accommodate a system volume of 125l at an average water temperature of 75°C and maximum system pressure of 3 bar.

  • Page 13: Appliance Sitting

    5.9 In high water volume systems or under fl oor heating systems, see section 15.2, where prolonged operation of the boiler is expected at temperatures below 60°C, a by-pass must be installed on the boiler outlet in order to prevent condensation forming inside the boiler body. Failure to comply with this requirement will invalidate the manufacturer’s guarantee.
