VERTICAL FLUE INSTALLATION

• Fit gasket (E) onto underside of vertical adaptor (O) – see diagram 10.

• Carefully insert ‘O’ ring (J) into vertical adaptor inner spigot.

• Place spacer (K) on the top of boiler.

• Fit vertical adaptor (O) onto spacer (K) ensuring adaptor inner connection locates correctly onto fan out-

let.

• For flat roof installation, fit flat roof flashing collar (part no. 85107)

• Fit extension pipes (M) as required.

• For pitch roof installation, fit pitch roof flashing (part no. 85105).

• Fit flue terminal (L) onto roof ensuring flashing makes a watertight joint.

Note: Maximum vertical height with no bends is 5 m.

Should it be necessary to cut the flue, always cut equal amounts from both inner and outer pipes.

Connect condensate trap (supplied) to vertical flue adaptor when flue length exceeds 3 m.

Connect 15 mm plastic pipe (not supplied) to a suitable drain.

For vertical flue lengths up to 3 m the restrictor must be left in the fan outlet, see diagram 9.

For vertical flue lengths between 3 and 5 m, remove the restrictor (R).

For each 90° flue bend fitted, reduce overall flue height by 1 m.

For each 45° flue bend fitted, reduce overall flue height by 1/2 m.
