4.3 PREPARE THE WALL - Figs. 10, 10A
1. Decide upon the position of the boiler taking into account the
clearances required for servicing and the flue terminal position.
2. Tape the template to the wall (ensure it is level and the right
way up) and mark the position of the holes for the boiler
mounting bracket and bottom fixings. If rear exit flue is used,
mark the position of the hole for the flue.
Note: If pipework is routed at the rear of the boiler (top pipe
connections), mark the four fixing holes shown in Fig. 10A.
3. Side exit flue - Continue the horizontal centre line of the flue
across the wall to the side wall, then along the side wall 190 mm
(ensure the lines are horizontal). This will give the position of the
centre of the hole for the flue.
4. Cut the 110 mm diameter hole (or use a 107 mm core drill) in
the wall for the flue.
5. Drill the fixing holes (8 mm dia.) to accept the No.10 plugs
supplied. Using the washers supplied with the screws, fit the
mounting bracket.
Note: When pipework is routed at the rear of the boiler, i.e. top pipe
connections the mounting bracket is not used. (Refer to fig. 10A).
Fit the top fixing screws, leaving just enough protruding, to hang
the boiler on.
6. Top pipe connections - Remove the mounting cross bar from the rear of the boiler and fit it to the top as shown in Fig. 10A.

4.4 FIT THE BOILER - Refer to Fig. 10
1. Lift the boiler and locate it on the mounting bracket or the top fixing screws when piping from above.
2. Adjust the position of the boiler, as necessary. Fit the bottom screws to secure the boiler in position (do not forget to
tighten the top screws when piping from above).
4.5 CONNECT THE PIPEWORK - Fig. 11
1. Thoroughly flush out all the water pipework.
Note: Ensure that all the plastic caps are removed from the boiler connections.
2. Secure all the valves/fittings to the boiler- use the washers supplied, ensuring they are facing the rear wall. Fit the union
bends to the valves.
Note: 1. If soldering to the boiler union bends, ensure the bends are not connected to the valves, otherwise the internal
seals may be damaged.
2. Ensure the 22 mm isolating valve with the filter is fitted to the heating return connection. (Refer to Fig. 11).
3. Fit the pressure relief valve connection before the isolating valves.
3. Connect the system pipework to the boiler.
Note: Do not forget that the pressure relief valve discharge pipe must be routed clear of the boiler to a drain in such a
manner that it may be seen, but cannot cause injury to persons or property.
4. Ensure that all the valves are closed (spindle flats at right angles to valve) and do not turn on the water or gas supplies at this stage.
