Horizontal Balanced Flue Kits 2358 & 2359
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.
Assembly Method (figs 21 to 22)
1. Having decided the position of the boiler, accurately mark
out the position of the terminal and cut a circular hole
130mm in diameter through the wall.
2. Secure the air box (
item 1
) and underside gasket (
3
) to
the top of the boiler using the nuts provided. Feed the
elbow (
4
) through the opening on the air box and fit to the
spigot in the top of the boiler, ensuring the open end is
directed towards the cutout in the wall.
3. Fit the remaining two gaskets (
3
) and cover (
2
) to the air
box, ensuring an air tight seal is made.
4. Ensuring the 'O'-ring seal (
8
) is in position and well-
lubricated, slide the flue mid-section (
5
) through the wall
and locate over the inner elbow and outer connection on
the air box. Secure in position using the clamping strap (
7
)
provided.
5. Slide the terminal (
6
) through the wall and locate in the
flue mid-section. Adjust the terminal length as required,
making sure a minimum distance of 140mm is kept from
the end of the terminal from the external face of the wall.
Alternatively, fit the flue terminal to the mid-section before
locating through the wall.
6. Connect the hose from the burner to the socket on the
internal air chute using the jubilee clip provided.
7. Seal around terminal on the inside and outside wall with
an appropriate material.
Important Notes:
(a) To aid assembly, it will be necessary to apply a thin bead
of lubricant to all flue joints which incorporate ‘O’-rings.
(b) As the flue system operates under positive pressure, all
flue joints must be well sealed. All joints which do not
incorporate ‘O’-rings must be sealed with silicone sealant.
(c) As the boiler produces condensate during normal running,
it is important that all seals are made and the correct
gaskets used.
(d) To ensure that any condensate produced in the flue drains
away, incline the flue slightly upwards from the boiler.
EXTENDING THE FLUE
Should the horizontal length of the standard flues not meet
your requirements, additional sections of flue pipe can be
purchased to extend the maximum wall thickness limit. 45º and
90º elbows can be purchased in order to offset the flue around
obstructions. See
page 29
for details.
TERMINAL GUARD
Where the terminal is positioned in a place where there is the
possibility of contact being made by persons, or of damage to
the terminal, an approved terminal guard is necessary.
Generally, exhaust 2 metres above ground level alleviates the
requirement for a terminal guard.
A suitable stainless steel terminal guard is available from
Trianco (part code
223920
).
