High-level balanced flue assembly
(kit 2357 in conjunction with 2355 or 2356)
Before starting, ensure the placement of each pipe
section has been identified (
fig 19 ), and that all 'o'-rings
are in position and are well lubricated. Any white pipe
exposed to the elements should be protected with a
suitable material. Place all weld seams to the rear.
Important: it is essential that the horizontal flue section
inclines slightly up from the boiler to allow condensation
to run back to the drain.
Before assembly, determine the length of flue required
and if necessary discard the middle section. See
adjacent for details of different available flue lengths.

Having decided the position of the boiler, mark the
position of the terminal and cut a circular hole
130mm diameter through the wall.

Remove the boiler top casing and the four nuts that
hold the flue socket and gasket to the top of the
heat exchanger. Remove the flue socket, but leave
the gasket in place.

Referring to fig 19 , secure items 8 , 7 , 6 & 5 in
order on to the top of the heat exchanger, using the
nuts previously removed.

Fit the lower flue section ( 4 ) to the spigot ( 6 )
—now
situated on top of the heat exchanger
—and ensure
the hose connection is directed to the front.

Fit the flue mid-section ( 3 )
—and any other optional
flue lengths
—to the preceding flue lengths in the
same manner, pushing firmly down until the outer
sections meet (but do not overlap). Use the
clamping strap (
2 ) to secure the outer sections
together.

Fit the horizontal flue elbow ( item 1 , fig 20 ) to the
top of the flue mid-section. Push firmly together
until the outers meet and secure with the clamping
strap.

Slide the terminal ( 4 ) into the horizontal mid-
section ( 2 ). Adjust the horizontal length as
required, ensuring a minimum distance of 140mm
is kept from the end of the terminal to the external
face of the wall. Seal the outer horizontal sections
together with a suitable material. See
figs 21
–
22
for allowable distances.

Slide the completed terminal assembly through the
wall from the inside and fit to the flue elbow. Push
firmly together until the outers meet and secure
with the remaining clamping strap.

Use the jubilee clip provided to secure the air hose
from the burner to the hose connection on the
lower flue section.

Remove the tabs from the cutout in the boiler top
casing and fit the casing in position around the flue.

Perform a final check of the flue. Ensure clamping
straps are located over all relevant flue joints.


To ensure that any condensate produced in the
flue drains away correctly, incline the flue 1°
upwards from the boiler. Seal any remaining gaps
in the wall around the flue with a suitable material.
Should the height of the flue (
figs 21
–
22 ) not meet your
requirements, alternative heights can be achieved by
discarding and adding different lengths. The vertical
mid-section (
item 3 , fig 19 ) can be discarded to
subtract 750mm from the total height. In this case, the
horizontal elbow should instead be fitted to the lower
flue section (
4 ) in the same manner.
Alternatively, additional sections of pipe can be
purchased to meet more specific requirements.
Additional 45° elbows can also be purchased to offset
the vertical flue run. See
page 26 for details.
For outputs 15
–26 kW, the total flue run—vertical and
horizontal
—must not exceed 6000mm. For outputs of
29
–36 kW, the total flue run must not exceed 4000mm.
Any 45° elbows contribute 500mm each to the
calculation. The 90° bend contributes 1000mm.
Where the terminal is positioned below 2 metres, or in a
place accessible to people, an approved terminal guard
will be required. A suitable stainless steel terminal
guard is available from Trianco (part code
223920 ).
