In the interest of safety, it is the law that all gas appliances are installed by a competent person in accordance with the above Regulations, Building Regulations/Building Standards Scotland, Codes of Practice, current I.E.E. Regulations and the byelaws of the Local Water Undertaking. Failure to comply with the Regulations may lead to prosecution; it is in your interest and that of safety to ensure that the law is complied with. Important - If the boiler is to be fitted in a timber framed building it should be fitted in accordance with the British Gas ...

NOTES * If a side outlet flue is to be used, a clearance of 75 mm will be needed on the flue outlet side of the boiler. ** Access to the front of the boiler must be available for maintenance (min. 600 mm).

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). 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. The flue must be in ...

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 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. If required an additional expansion vessel may be fitted to the central heating return inlet. 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. Pump performance curve Grundfos UPS 25-60 1 2 3 Sp ...

1.0 UNPACKING The appliance is delivered in 2 cartons. 1.1 The large carton contains the boiler, and the Installation/Servicing and Users Instructions. 1.2 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 turret. When the cartons are unpacked examine for any signs of damage in transit. All protective plastic should be left in place until installation is complete. 2.0 FIXING THE MOUNTING JIG ON TH ...

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.). Ensure all pipework is adequately supported.

4.1 Rear Flue Outlet (fig. 12) Important - The aluminium flue pipe must protrude into the outside grill by 2 in (50 mm), never cut it to the same length as the plastic air pipe (aluminium flue pipe = plastic air inlet pipe + 50 mm !). Aluminium flue pipe length = Plastic air inlet pipe length plus 50 mm (2") longer. 4.1.1 Accurately measure the Wall thickness (P1) 4.1.2 From the end opposite to the terminal, cut the plastic air duct (dimension A1) to length (P1 + 105 mm). Note - That the terminal is not included in A1. 4.1.3 Cut the metal flue duct to length (P1 + 155 mm) (dimensions F1). Note - The metal flu ...

5.1 Place the boiler on its back. 5.2 Remove the boiler base plate, four screws (fig. 16). Remove the plugs fitted to the boiler water connections.

7.3.1 To be wired to terminals 7 and 8 on the appliance connector box (see fig. 18), low voltage twin wire can used. 7.3.2 External sensor location The external sensor should be installed on the North, North-West wall or on the one facing the majority of the main living rooms in the building. The sensor must never be exposed to the first morning sunlight. It must never be subjected to direct sunlight and should be protected if necessary. In no case may the sensor be mounted near windows, doors, ventilation openings, stacks or heat sources which could alter its reading. Fig. 19b Fig. 19a ...

The boiler can now be regulated to ensure the design critia of the system is matched to the outside tempera- ture 7.4.1 Consult the outside compensation graph provided (fig. 19c) 7.4.2 Following the bottom ouside temperature line to find the outside temperature. The system is designed for. 7.4.3 Trace a line vertically until you reach the designed system flow temperature. 7.4.4 Read from the graph the number setting that the boiler is to be adjusted to. If the setting is between two numers this can be set on the boiler, say between 2 and 3. 7.4.5 Remove the plastic cover of the outside compensation adjustment s ...
