15 INSTALLING THE FLUE
FITTING FLUE THROUGH THE WALL
1. Measure wall thickness and add 14mm.
2. Measure from the outer terminal lip towards the end of outer flue, place a
small location mark at the dimension acquired at point 1.
3. Fit external black wall seal ensuring the inside of the outer lip is in contact
with the terminal lip you have been measuring from (see fig 1)
4. For an internal fit, place flue terminal in the centre of the 5" drilled hole
in the wall. Apply pressure and lightly move the flue left to right or up
and down. This will cause the outer flange to fold in and allow the flue to
pass through the wall.
5. Push through a further 65mm. This will allow the outer flange to return
to its original shape.
6. Pull back the flue until the location mark point 1 is level with the internal
face of the wall.
Note. If the location mark is not visible then the flue is not pulled back
far enough to obtain the correct seal. If the location mark has passed
the face of the wall the flue has been pulled to far back and the outer
wall seal will have been dislodged from its mounting and will need to be
refitted.
7. Ensure the seam and the outlet terminal are at the top and fitted as shown.
Note. If less than 50% of the length of the flue is internal the flue should be
fitted from outside.

FITTING THE TURRET - Ensure the condense trap/siphon is filled with water
1. Ensure the rubber seal is fitted correctly on the appliance manifold and that all flue seals are undamaged.
2. Hold the flue firmly and push the turret on until it has travelled 30mm on to the flue pipe and is fully engaged. Make sure the
flue has not rotated or moved forward during fitting and the flue seam is upper most.
3. Push the turret into the manifold ensuring the upper plastic lip is flush with the top of the manifold.
4. Fully engage the clamp location section into the manifold location holes. Rotate down on to turret flange.
5. Secure clamp to appliance using securing screw.
6. Ensure all sample points are accessible and all sample plugs and caps are fitted.
