4.0PREPARING THE FLUE ASSEMBLY

4.1Rear Flue Outlet (fig. 12)

Important - The aluminium flue pipe must protrude into the outside grill by 60 mm, never cut it to the same length as the plastic air pipe (aluminium flue pipe = plastic air inlet pipe + 70 mm !).

Aluminium flue pipe length = Plastic air inlet pipe length plus 70 mm longer.

K = 10 mm min. 60 mm max.

4.1.1Accurately measure the Wall thickness (P1)

4.1.2From the end opposite to the terminal, cut the plastic air duct (dimension A1) to length (P1 + 192 mm).

Note - That the terminal is not included in A1.

4.1.3Cut the aluminium flue duct to length (P1 + 262 mm) (dimensions F1).

Note - The aluminium flue pipe must be 70 mm longer than the plastic air inlet pipe.

4.1.4Drill a 3 mm hole 15 mm from the plain end of plastic air duct.

4.1.5Place flue components to one side to be

used later.	Rear flue Outlet

4.2Side Flue Outlet (fig. 13).

Important - The aluminium flue pipe must protrude into the outside grill by 60 mm, never cut it to the same length as the plastic air pipe.

Aluminium flue pipe length = Plastic air inlet pipe length plus 70 mm longer.

4.2.1Accurately measure the Wall thickness (P2).

4.2.2Accurately measure the distance from the centre of the stud fixing of the mounting jig assembly to the side wall (Q2).

4.2.3From the end opposite to the terminal, cut the plastic air duct (dimension A2) to length (P2 + Q2 + 180 mm).

Note - That the terminal is not included in length A2.

4.2.4Cut the aluminium flue duct to length (P2 + Q2 + 250 mm) (dimension F2).

Note - The aluminium flue pipe must be 70 mm longer than the plastic air inlet pipe.

4.2.5Drill a 3 mm hole 15 mm from the plain end of plastic air duct.

4.2.6Place flue components to one side to be used later.
