INSTALLATION & SERVICING INSTRUCTIONS FOR WORCESTER GREENSTAR 25Si/30Si
FLUE INSTALLATION
Installing the standard flue:
1 Set the flue length to the distance required,
secure with screw and seal joint with the
aluminium tape supplied.
Slide the inner wall seal (A) onto the terminal (B)
as shown.
If fitting from inside the building; slide the outer
wall seal (C) onto the terminal (B) as shown.
2 Remove the three screws (D, H) around the flue
outlet (F) on the boiler.
Check the boiler flue seal is correctly seated.
Apply silicone grease to the boiler flue seal.
3 Position terminal (B) through the flue opening in
the wall to the outside of the building by the
distance shown.
The flue terminal MUST be fitted with the 'TOP'
label uppermost to allow the correct fit and use of
the plume management system.
4 Align the flue turret (E) to the boiler flue outlet (F)
with flat (G) facing to the rear of the boiler.
Push the flue turret (E) straight down into the
boiler flue outlet (F).
For ease of assembly, locate screw (H) first and
then fit screws (D) to secure flue turret (E).
If fitting from the outside of the building; slide the
outer wall seal (C) onto the terminal (B) as
shown.
NOTE:
For more information refer to the
60/100 Horizontal Flue kit Instruction Manual
FLUE TERMINAL PLUME RE-DIRECTION:
The flue discharge can be re-directed allowing
some plume redirection control, alternatively, a
complete plume management system can be
fitted to the flue terminal.
Re-directing the flue discharge:
1 Remove screws (A) and rotate the terminal end
(B) through 180°.
DO NOT rotate the complete flue terminal
assembly.
2 Refit the terminal end (B) and secure with screws
(A).
3 Loosen screws (C) and rotate the entire outlet
assembly to redirect the plume. Retighten screws
(C) to secure in the required position.
NOTE: The flue terminal outlet has built-in stops to
limit rotation for horizontal fluing to allow
condensate to run back into the boiler for
safe disposal. Do not attempt to force beyond
the limit stops.
