Horizontal balanced flue assembly
(kits 2334 & 2335)
Before starting, ensure the placement of each section
has been identified and that all 'o'-ring seals are in
position and well-lubricated.
Important:
it is essential that the flue inclines slightly
up from the boiler to allow condensation to run to the
drain.
Having decided the position of the boiler, mark out
the position of the terminal and cut a circular hole
130mm diameter in the wall (see
figs 17
–18
).
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.
Fit the sealing plate (
item
4
,
fig 16
) over the four
studs and place the terminal gasket (
3
) over the
sealing plate. Position the boiler.
Assemble the flue by sliding the terminal section
(
2
) into the elbow section (
1
), ensuring that all 'o'-
rings (
6
) are in position. Slide the completed
assembly through the wall from the inside.
Slide the flue mounting plate on the elbow section
over the four studs on the top of the heat
exchanger and secure in position using the four
nuts previously removed.
Adjust the terminal length as required, ensuring a
minimum distance of 140mm is kept from the end
of the terminal to the external face of the wall. See
figs 18
–
19
for allowable distances.
Connect the air hose from the burner to the socket
on the near end of the flue, using the jubilee clip
provided.
To ensure that any condensate produced in the
flue drains away correctly, incline the flue 1°
upwards from the boiler. Seal around the terminal
on the inside and outside wall with an appropriate
material.
As the flue operates under positive pressure, all
flue joints must be well-sealed. To aid assembly, it
may be necessary to apply a thin bead of silicone
grease to all flue joints that incorporate 'o'-ring
seals. All joints that do not incorporate 'o'-ring
seals should be sealed with silicone sealant.
As the boiler produces condensate during normal
running, it is important that all seals are made and the
correct gaskets used.
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 TR Engineering (part code
223920
).
