Horizontal flue installation
1. Define the position for installing the unit.
2. If using standard flue (041049G0) this must be installed level. For extended horizontal flue lengths over 1m a fall of
3 mm per metre of the flue exhaust should be incorporated back to the boiler.
3. Make a hole of diameter 10 - 20 mm greater than the nominal diameter of the concentric pipe used.
4. If necessary, cut the terminal length to size, ensuring that the external pipe protrudes from the wall by between 10
and 60 mm. Remove the cutting burrs.
5. Connect flue to the boiler, positioning the seals correctly. Seal the flue into the wall with silicone or sand + cement
and cover with wall seals provided.
Flue seals should be lubricated with a silicone type grease to prevent damage (grease not supplied).
