21 WALL MOUNTING TEMPLATE

Note. The template shows the positions for the fixing holes and the flue hole centres for standard installation.

If the flow and return pipes are to be routed down behind the boiler the downward routing pipe bracket, supplied with the Downward Piping Kit, must be used. This bracket is secured to the wall and it is essential to use only those holes as shown on the wall mounting template.

Care MUST be taken to ensure the correct holes are drilled.

1.Tape the template into the selected position.

2.Ensure squareness by hanging a plumb line as shown.

3.Extend the flue centre line onto the side wall and measure in 120mm for standard installation or 156mm when using downward routing pipe kit.

4.Mark onto the wall the following:

a.The 2 wall mounting plate screw positions (choose one from each group).

b.The fixing hole for the jacking screw.

c.The position of the flue duct hole.

Note. Mark the centre of the hole as well as the circumference.

5.Remove template from the wall.

22 PREPARING THE WALL

IMPORTANT. Ensure that, during the cutting operation, masonry falling outside of the building does not cause damage or personal injury.

1. Cut the flue hole, preferably with a 125mm (5") core boring tool, ensuring that the hole is square to the wall. If the hole has been accurately cut with a drill then making good the inner wall face is not essential as a seal is provided (an optional extra outer wall seal is required if necessary). However, both wall faces immediately around the cut hole should be flat; make good if necessary. For less accurate holes make good to approximately 125mm (5") diameter at the 2 wall faces.

2.Drill 3 holes, 2 for the wall mounting plate and 1 for the jacking screw with an 8mm (5/16") masonry drill.
