3.10 When installing the horizontal terminal, decide on the
terminal position and measure the height from the top of
the appliance to the centre of the required hole. Refer to
section 2 in Site Requirements for minimum and maximum
flue dimensions.
3.11 A 152mm (6") diameter hole is required to install the flue.
This can be achieved by either:
a) Core drill
b) Hammer and chisel
It is advisable to drill small holes around the circumference
when using method b. Make good both ends of the hole.
NOTE: TAKE CARE WHEN MARKING OUT THE FLUE AS
IT IS VERY DIFFICULT TO MOVE AFTER INSTALLATION.
3.12 Only the horizontal terminal section can be reduced in size.
To determine the length, measure from the outside of the
wall to the stop on the 90-degree elbow. Measuring from
the slots on the outer flue furthest away from the outlet,
add 10mm onto the required measured length and mark
around the flue. See diagram 8.
3.13 A wall plate is supplied to secure the flue to the wall. Bend
the tab to 90°. Assemble the plate onto the flue but only
secure to the wall and flue when the flue is fully assembled.
See diagram 8.
