8.0INSTALLATION
8.4Fitting The Boiler
1.Lift the boiler using the lower edges. Engage the slots at the top rear of the boiler on the wall plate hooks (Fig. 20).
2.Ensure that the boiler is level and sits against the wall.
3.Take the two steel washers and remaining screws. Using the previously drilled and plugged holes, secure the bottom of the boiler to the wall (Fig. 21).
4.Remove the elbows, valves and sealing washers from the packaging. The 3/4 in valve with internal filter must be fitted to the central heating return. The filter is visible through the branch connection of the valve.
5.Using the sealing washers provided connect the valves to the heating flow and return, and the cold water inlet.
6.Connect the elbows to the gas service cock and hot water outlet pipe, and then connect the elbows to the boiler. Connect the elbows with flared ends to the valves.
7.Ensure that the sealing washers are used on all connections. The rubber washers must be used on the gas connections.
8.The gas and water supplies, central heating flow and return and domestic hot water flow can now be connected.
8.5Fitting the Pressure Relief Discharge Pipe (Fig. 22)
1.Remove the discharge pipe from the kit.
2.Determine the routing of the discharge pipe in the vicinity of the boiler. Make up as much of the pipework as is practical, including the discharge pipe supplied.
3.The pipework must be at least 15mm diameter and run continuously downwards to a discharge point outside the building. See section 6.7 for further details.
4.Using one of the sealing washers, connect the discharge pipe to the adaptor and tighten the nut.
5.Complete the discharge pipework and route it to the outside discharge point.
IMPORTANT: Make all soldered joints before connecting to the pressure relief valve.
