High-Level Balanced Flue Kit (2357)
Before commencing assembly, please make sure that you have correctly identified the placement of each pipe section and
that all 'O' ring seals are in position and well-lubricated. Any white pipe exposed to the elements should be protected with a
suitable material. Place all weld seams to the rear.
ASSEMBLY METHOD
Before assembly, determine the length of flue required and if
necessary discard the mid-section. See "alternative vertical
lengths" (adjacent) for details of different flue lengths.
1. Having decided the position of the boiler, cut a hole
130mm diameter in the wall. Refer to fig 25 and
"alternative flue heights" for high level flue positions.
2. Ensuring the 'O'-ring seal (3) is in position and well-
lubricated, fit the flue mid-section (4) into the spigot
attached to the boiler, pushing the outer sections of pipe
firmly together. Use the clamping strap (2) to fasten these
items securely to create a seal.
3. Fit the lower flue section (item 4) to the spigot (item 6),
now situated on top of the boiler, ensuring the 'O'-ring
creates a good seal.
4. Ensuring that all 'O'-ring seals are in position and well-
lubricated, fit the elbow (item 1, fig 23) from the horizontal
balanced flue kit to the top of the flue mid-section, pushing
firmly together until the outer sections meet. Use the
clamping strap to fasten these items securely together.
5. Decide the length of horizontal run required and slide the
terminal (item 4, fig 23) into the horizontal mid-section
(item 2, fig 23). Once in the required position (and
ensuring that at least 140mm will project from the outside
wall), seal these items together using a suitable material.
6. Ensuring that all 'O'-rings are in position, slide the
completed terminal assembly through the wall and fit to
the flue elbow, pushing firmly together until the outer
sections meet. Use the remaining clamping strap to fasten
these items securely together.
7. Use the clip provided to secure the air hose from the
burner to the connection on the air box assembly inside
the boiler.
8. Perform a final check of the flue. Ensure all clamping
straps are located over all relevant flue joints.
9. Seal any remaining gaps in the wall around the horizontal
flue section with a suitable material.
ALTERNATIVE FLUE HEIGHTS
Should the height of the flue (see fig 25) not meet your
requirements, alternative arrangements can be made by
purchasing additional sections of flue pipe to extend the
vertical distance. See page 29 for details.
ALTERNATIVE HORIZONTAL LENGTHS
Should the horizontal length of the standard flues not meet
your requirements, an additional section of flue pipe can be
purchased to extend the maximum wall thickness limit. See
page 29 for details.
ADDITIONAL ELBOWS
When used in conjunction with additional horizontal lengths
of flue, 45º and 90º elbows can be purchased in order to
offset the flue on the horizontal plane. See page 29 for
details.
Additional 45º elbows can be purchased to offset the vertical
sections of flue. 90º elbows cannot be used on the vertical
sections. See page 29 for details.
The total flue distance, vertical and horizontal, must not
exceed 6000mm. Any 45º elbows used in the assembly
contribute 500mm to the calculation. 90º elbows contribute
1000mm to the calculation.
To ensure that any condensate produced in the flue drains
away correctly, incline the flue slightly upwards from the
boiler.
TERMINAL GUARD
Where the terminal is positioned in a place where there is
the possibility of contact being made by persons, of damage
to the terminal, or if it is lower than 2 metres from ground
level, an approved terminal guard is necessary.
Generally, exhaust 2 metres above ground level will
alleviate the requirement for a terminal guard.
A suitable stainless steel terminal guard is available from
Trianco (part code 223920).
