26 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 the flue outlet A.
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.
3.
Locate the flue turret on
the top of the boiler,
ensuring that the turret
gasket is in place.
Check that the flue seal
‘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 4 wall
plugs and wood screws.
NB.
The space bracket will utilise one fixing hole only
whilst used in conjunction with the stand-off option.
