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.
