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.
