6.0SYSTEM DETAILS

6.5System Filling and Pressurising

1.A filling point connection on the central heating return pipework must be provided to facilitate initial filling and pressurising and also any subsequent water loss replacement/refilling.

2.There are connection points on the mains cold water inlet and central heating return isolating taps to which the optional filling loop kit (Part No. 248221) can be assembled.

3.The filling method adopted must be in accordance with all relevant water supply regulations and use approved equipment.

for GB: Guidance G24.2 and recommendation R24.2 of the Water Regulations Guide.

for IE: the current edition of I.S. 813 “Domestic Gas Installations”.

5.The sealed primary circuits may be filled or replenished by means of a temporary connection between the circuit and a supply pipe, provided a ‘Listed’ double check valve or some other no less effective backflow prevention device is permanently connected at the inlet to the circuit and the temporary connection is removed after use.

6.6Expansion Vessel (Central Heating only)

1.The appliance expansion vessel is pre-charged to 0.5 bar. Therefore, the minimum cold fill pressure is 0.5 bar. The vessel is suitable for correct operation for system capacities up to 125 litres. For greater system capacities an additional expansion vessel must be fitted. For GB refer to BS 7074 Pt 1. For IE, the current edition of I.S. 813 “Domestic Gas Installations”.

6.7Pressure Relief Valve (Fig. 9)

1.The pressure relief valve is set at 3 bar, therefore all pipework, fittings, etc. should be suitable for pressures in excess of 3 bar.

2.The pressure relief discharge pipe should be not less than 15mm dia, run continuously downward, and discharge outside the building, preferably over a drain. It should be routed in such a manner that no hazard occurs or causes damage to wiring or electrical components. The end of the pipe should terminate facing down and towards the wall.

3.The discharge must not be above a window, entrance or other public access. Consideration must be given to the possibility that boiling water/steam could discharge from the pipe.
