    7. INSTALLATION POSITIONING BOILER Ensure that adequate clearance is available for making the water and flue connections. As the boiler is serviced from the front, no headroom clearance is necessary but a clearance of 750mm must be available at the front of the boiler. No special hearth is required as the boiler is fully insulated, but the floor must be level and capable of supporting the weight of the boiler and its water content.
  • Page 27 7. INSTALLATION CONDENSATE DISPOSAL IMPORTANT Firebird condensing boilers when in condensing mode extract more heat from the flue products and the resulting condensate which is mildly acidic needs to be drained from the boiler via a condensate pipe to the drainage system. Provision must be made for the removal of condensate from the boiler to a internal soil stack, waste pipe, external soil stack, gully or soak-away as per BS6798.
  • Page 28 7. INSTALLATION CONVENTIONAL FLUE SYSTEMS IMPORTANT The Firebird condensing boiler must not be installed with existing flue systems. A flue system suitable for wet flues must be used. If a flue system which is unsuitable is used it will invalidate the warranty. Because of the high operating efficiencies of the Firebird condensing boilers and low flue gas temperatures, it is necessary to pay extra special attention to the flues and chimneys.

Below opening, airbrick, opening window etc. Book three Aug. 2002 See note at foot of page Notes: The terminal should be positioned to avoid combustion products entering the building or accumulating in stagnant pockets around buildings.
  • Page 30 7. INSTALLATION Clearances advised by the BRITISH STANDARDS for Open Flues, Low Level Balanced Flues and Balanced Flues fitted to Oil Fired Boilers. THESE ARE ALSO THE BUILDING REGULATIONS FOR ENGLAND, WALES & SCOTLAND Minimum distances to terminals in millimetres as measured from top of the chimney or the rim of a low level discharge opening.
  • Page 31 7. INSTALLATION BALANCED FLUE BOILERS The Firebird boiler may be set for Room-sealed balanced flue operation using a Firebird condensing balanced flue kit. This kit does not draw combustion air from inside the room. It is drawn from ☛ outside direct to burner by airpipe supplied with boiler. Flue gases are expelled expelled through ☛...
  • Page 32 7. INSTALLATION Ventilation and Combustion Air Conventional Flue Boilers An adequate supply of combustion and ventilation air is essential for efficient and safe boiler operation and the openings for this should be positioned to cause least possible draught, with no possibility of being accidentally blocked.

    9. OIL SUPPLY OIL STORAGE TANK SITING Consult OFTEC Manuals It is very unlikely that a fire should start from a domestic oil tank, however it does need to be protected from a fire which may originate in a building nearby. For this reason, the tank should be located at least 1.8 metres from any building and no closer than 760mm from any boundary.
  • Page 40 9. OIL SUPPLY TWO PIPE SYSTEMS Where installations have the bottom of the tank below the oil burner pump a two pipe system is required. Ensure that valves and filters are not fitted in the return line as this must be unobstructed at all times. The oil burner pump should be set for two pipe operation as detailed in accompanying oil burner manufacturers manual, refer also to page 15 of this manual.

  • Page 41: Commissioning

    10. COMMISSIONING It is recommended that commissioning is carried out by a competent and qualified service engineer. It should be noted that it is the responsibility of the installer to ensure that the boiler is properly commissioned. Failure to do so may invalidate the boiler guarantee and any extended warranty.

Ensure that any capillary fittings used are of lead free solder variety. For user comfort the mains pressure at taps should be between I and 5 bar. If it exceeds this it is advisable to fit a pressure reducing valve adjusted to reduce pressure to an acceptable level within above range.
  • Page 49 13. DOMESTIC HEATING & HOT WATER SYSTEM FILLING, TESTING AND MAKE-UP Introduction Mains cold water is supplied through the boiler pipework to two separate circuits operating at different pressures. Circuit One This is the Radiator Heating System including boiler and primary tank which is filled from mains supply via flex filling loop (Page 45) within boiler to a pressure determined from system static head, expansion vessel size and system water volume.This flexible filling loop should be disconnected when boiler and system are filled and checked, See diagrams below.
  • Page 50 13. DOMESTIC HEATING & HOT WATER SYSTEM FILLING, TESTING AND COMMISSIONING * Before proceeding to filling, ensure that electricity supply is switched off at mains to avoid any possibility of time switch operating and passing power to appliance prior to filling.
