FLUE ASSEMBLY - Exploded view
For wall thickness 270mm to 775mm
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.

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.
