PREPARATION OF THE FLUE DUCT

2.6.1 Place the firebox into the fire opening with fire surround correctly
secured in the final position. From the outside of the house measure
from the face of the outside wall to the rear panel of the firebox through
the flue hole. Cut the flue duct to this size, using the polythene support
ring to support the flue whilst being cut. Remove the polystyrene
support ring from the flue duct and remove burrs from the pipe.
IMPORTANT : ENSURE THE PIPES ARE CUT SQUARELY.
2.6.2 The joint between the firebox and the flue duct as shown below in figure
9 must be secured with screws and sealed with the foil tape as
supplied. In order to do this, the wall plate must removed from the flue
pipe / termination.

2.6.3 Due to the varying lengths of flue that will be required via differing
installations it will be necessary to drill the flue pipe using the 3 off holes
in the mounting flange on the rear of the combustion chamber as a
guide for positioning. When the holes have been drilled and the screws
fitted, wrap the joint with the foil tape supplied.
2.6.4 Re-fit the wall plate ensuring the outer set of holes as indicated above
in figure 9 are used. Use a high temperature sealant to secure the wall
plate to the outside wall of the property before securing with the screws
and rawlplugs supplied to ensure a mechanical fix.
