  • Page 8: Installation Details

    Local Gas Region of British Gas Plc. Location of Boiler The installation of the FER must be on a suitable non-combustible load bearing wall which will provide an adequate fixing for the boiler mounting bracket assembly. The location should be in an area where the water pipes will not be subjected to frost conditions.
  • Page 9 INDUSTRIE Terminal Position Fig. 3 Minimum Clearance mm Fig. 5 NOTES * Access to the front of the boiler must be available for maintenance (min. 600 mm).

  • Page 10: Flue System

    INDUSTRIE 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. It is absolutely essential, to ensure that products of combustion discharging from the terminal cannot re-enter the building, or enter any adjacent building, through ventilators, windows, doors, natural air infiltration, or forced ventilation/air conditioning.

Bypass Fig. 6 NOTE: A bypass must be fitted as far as possible from the boiler if thermostatic radiator valves are fitted throughout. TEMPORARY FILLING LOOP A temporary filling loop of the above type conforming to WRC approval should be installed between the cold water mains and the central heating system 1.
  • Page 12 INDUSTRIE Built-in Central Heating Water Circulating Pump The pump head available for circulating the water is given in fig. 8. N.B. - The pump is factory set at position 3. The pump is a Grundfos type 25-50 UPS series. Note - Minimum flow through boiler heat exchanger at any time should not fall below 6 litres per minute. If the total volume of water in the system exceeds 40 litres an additional expansion vessel must be fitted to the central heating return inlet.

  • Page 13: Unpacking

    INDUSTRIE Note - To mount the boiler on the wall, a two person lift will be needed. UNPACKING The appliance is delivered in three cartons. The large carton contains the boiler, and the Installation/Servicing and Users Instructions. The second carton contains the valves, fixing bolts and flue bend. The third carton contains the flue assembly.
