4.2.7 Installing Flue System with 90° Turning Kit
It is possible to install the flue system with 1 or 2 pieces of 90° turns
between the boiler and the wall, provided that the total lengths allowed
are not exceeded. Refer to Fig.20 for installation.

(For installation with two turns)
For a required "N" distance;
Prepare straight inner duct (19)of "N - 132" lenght and straight outer duct(18) of "N - 172" lenght.
Refer to Fig.17 for cutting operation.
Fit both inner and outer cut straight ducts to elbows (15) at both ends with
elbow seals (9) and clamps (7) and secure the clamps with screws(8).

To complete the installation from turning point to the boiler for a required lenght "M",
prepare straight inner duct of "M - 132" lenght and straight outer duct of "M - 172" lenght.
Complete the installation as described in step2 between the elbow (15) and the elbow with flange (1).
(To achieve this distance, an extension kit of necessary lenght
can be used between the elbow with flange and the straight ducts.)

Measure lenght "L" from the wall outlet point (A) back to the 90° turning point (B)
at the place of installation and install the terminal duct according to this lenght.
Installation is done as described in Fig.14 or Fig.15 according to lenght "L".
Use elbow (15) instead of elbow with flange (1).

The flue system can be installed without any 90° turning kit for positions shown in Fig.A below.
1 or 2 90° turning kit has to be used in positions like in Fig.B where the line from centerline of boiler outlet
to the outlet wall surface is not perpendicular.
Maximum total lenght "M+L" can be 2200 mm. for installations with one turning kit and
Maximum total lenght "M+N+L" can be 1200 mm. for installations with two turning kits.

Secure the flue system from the elbow (1) to here with
4 self-tapping screws, such that the elbow gasket (6) will seat in between.

4.2.8 Installing Flue System with Elevation Kit
It is also possible to elevate the flue system on top of the boiler before it makes the first turn
to its horizontal path. Flue elevation kit has to be used for this purpose and it can be applied to
any of the standard, extended and 90° turning flue systems described in the three sections
above. Refer to Fig.21 to carry out the operation. The figure shows how to provide the
