protective packaging.
Note.
The template shows the positions of the fixing holes and
the rear flue hole centre for standard installation. Care
MUST be taken to ensure the correct holes are drilled.
1. Tape template into the selected position. Ensure
squareness by hanging a plumbline as shown.
2. If fitting a side flue extend the flue centre line onto the side
wall and measure in 155mm for standard installation.
Note. If using stand-off kit distance increases to 188mm.
3. Mark onto the wall the following:
a The wall mounting plate screw positions (choose one
from each group).
b. The position of the flue duct hole (see diagram below).
Note. Mark the centre of the hole as well as the
circumference.
4. Remove the template from the wall.
15 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 5" core boring
tool), ensuring that the hole is square to the wall.
Both wall faces immediately around the cut hole
should be flat.
2. Drill 4 holes with a 7.5mm / 8mm masonry drill
and insert the plastic plugs provided, for the piping
frame.
3. Locate 4 No.14 x 50mm screws in the piping
frame (one at each side, in any of the 3 holes
provided at each side) and screw home.
