d. For left hand side flue add 48mm (1
7/8
")
i.e.
for RHS
X + H + 132mm (5
3/16

for LHS
X + H + 48mm (1
7/8
")

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 3 holes with a 7mm (
1/4
") masonry drill and insert the plastic
plugs, provided, for the wall mounting plate and the jacking
screw plate.
Note.
If the terminal is to be sited within 25-40mm of a corner or
vertical pipe (refer to Table 3) then the hole MUST be accurately
cut and the rubber weather seal trimmed around the groove
provided. The terminal wall plate need not be fitted.
3. Locate 2 of the No.10 x 2" screws in the wall mounting plate (1 at
each side, in any of the 3 holes provided at each side) and screw
home.
