    Terminal Position Fig. 3 Minimum Clearance Fig. 5 NOTES * Access to the front of the boiler must be available for maintenance (min. 600 mm).

  • Page 10: Water System

    Flue system The boiler allows the flue outlet to be taken from the rear of the boiler or from either side. A standard flue length of 0.75 metres is provided. Alternative lengths of two or three metres can be supplied (equivalent to wall thicknesses of up to 565, 1815 and 2815 mm for rear flues and deduct 91 mm plus distance from side wall for side outlet flues).

The pump is a Grundfos type 15-50 UPS series. Grunfos Pump performance graph Note - Minimum flow through boiler heat exchanger at any time should not fall below 6 litres per minute.
  • Page 13 Installation Note - To mount the boiler on the wall, a two person lift will be needed. UNPACKING The appliance is delivered in 2 cartons. The large carton contains the boiler, and the Installation/Servicing and Users Instructions. The second carton contains the mounting jig assembly, complete with isolating valves, the assembly fixing screws and wall plugs (x4), the boiler mounting nuts and washers (x2), drilling template, flue assembly and flue bend.

  • Page 14: Drilling Template

    Important Note - Always use two spanners to prevent twisting of soft copper pipework on the boiler. Flush out the water system. Note - The maximum inlet cold water pressure must not exceed 10 bar (145 P.S.I.) and a water governor or a pressure reducing valve will be required if the pressure is in excess of 5 bar (72 P.S.I.).

  • Page 15: Preparing The Flue Assembly

    PREPARING THE FLUE ASSEMBLY Rear Flue Outlet (fig. 12) Important - The aluminium flue pipe must protrude into the outside grill by 60 mm, never cut it to the same length as the plastic air pipe (aluminium flue pipe = plastic air inlet pipe + 70 mm !). Aluminium flue pipe length = Plastic air inlet pipe length plus 70 mm longer.

  • Page 16: Connecting The Boiler

    CONNECTING THE BOILER Place the boiler on its back. Remove the boiler base plate, four screws (fig. 16). Remove the plugs fitted to the boiler water connections. Remove the bag of sealing washers from the boiler pipework. Remove the front panel by gripping on both sides, sliding up and pulling away from the main boiler.
