CONNECTING THE FLUE TO THE BOILER
Note.
Before fitting the flue turret fill
the condensate trap within the
boiler by pouring a cupful of
water into flue outlet A.
Make sure the plastic cap is
removed from the end of the
condensate drain adapter.
Take care to ensure that the
water is only poured into the flue
outlet, and does not spill into the
boiler casing.
1. Locate the flue into the turret.
2. Insert the flue assembly through the prepared hole in the
wall. Push through and pull back to seal against outside
wall face.
3. Locate the flue turret on the top of the boiler, ensuring that
the turret gasket is in place. Also ensure the turret is
located concentric with the flue aperture on the boiler top
panel. Check that the flue seal (at A) located in the top of
the flue manifold is secure and giving an effective seal.
4. Secure the flue turret on top of the boiler by inserting the
open ends of the turret clamp under the 2 studs and fixing
it in the middle with the single M5 x 10mm pozi-hex screw
provided.
5. Flues over 1 metre long.
Fix the flue support bracket to the wall, using the wall plug
and wood screw. For standard installations use the short
wood screw.
If the stand-off option is used, secure the support bracket
using the spacer bracket and long wood screw.
NB. The space bracket will utilise one fixing hole only whilst
used in conjunction with the stand-off option.

drilled hole in the wall and fix in position with the
No.10 x 2" screw provided.
