HORIZONTAL FLUE INSTALLATION
A Air inlet pipe
B Terminal
C Seal and clamp
D Elbow
E Gasket
F Screws
G External rubber sealing collar
I Internal plastic collar
J ‘O’ rings
K Spacer (see diagram 9)
Fit gasket (E) onto underside of flue elbow (D).
Carefully insert ‘O’ ring (J) into upper and lower parts of inner elbow.
Place spacer (K) (supplied with boiler) onto top of boiler (see diagram 9).
Fit elbow onto spacer ensuring elbow inner connection locates correctly onto fan outlet.
Fit external rubber sealing collar (G) onto air inlet pipe (A).
Fit flue through hole in wall and pull up so that external collar (G) is flush against outside wall.
Fit seal and clamp (C) to flue and assemble into elbow (D) making sure that both inner and outer pipes are
sealed properly.
Note: Maximum horizontal length with no bends is 3 m. For horizontal flue lengths up to 1 m the restrictor must
be left in the fan outlet, see diagram 9. For horizontal flue lengths between 1 and 3 m, remove the restrictor (R).
Tighten up clamp using screws provided.
Note: Should it be necessary to cut the flue, always cut equal amounts from both inner and outer pipes.
Always cut the end furthest from the terminal.
For each 90° flue bend fitted, reduce overall flue length by 1 m.
For each 45° flue bend fitted, reduce overall flue length by 1/2 m.
