10 WALL MOUNTING TEMPLATE

Note. The template shows the positions for the fixing holes
and the flue hole centres for standard installation. Care must
be taken to ensure the correct holes are drilled.
1. Separate the templates.
2. Tape the templates into the selected position.
3. Ensure squareness by hanging a plumb line as shown.
4. Mark onto the wall (if required) the following:
a. The wall mounting plate screw positions (choose
one from each group). Note. Mark the centre of the
flue hole as well as the circumference.
b. The position of the flue duct hole.
c. Downward pipe routing bracket screw positions.
5. Remove the templates from the wall.

11 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 quite accurately cut with a drill
then making good the wall faces is not essential as
seals are provided at both ends of the flue. 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 4 holes for the wall mounting plate with an 8mm
( ") masonry drill. If the stand-off brackets are used
5/16
ensure the correct holes are chosen.
3. Insert the plastic plugs provided.
