Terminal assembly
PN-0000462
There are two telescopic sections, the terminal assembly and the
connection assembly, a roll of sealing tape and two self-tapping screws.
A 93° elbow is also supplied.
The two sections can be adjusted to provide a length between 315mm and
500mm when measured from the flue elbow (there is 40mm engagement
into the elbow).
1.
Locate the flue elbow on the adaptor at the top of the boiler. Set the
elbow to the required orientation.
Important
The flue elbow is angled at 93° to ensure a fall back to the boiler.

Flue dimension X
2.
Measure the distance from the outside wall face to the elbow. This
dimension will be known as " X”.
3.
If the distance from the flue elbow to the outside face of the wall is
less than 250mm the connection assembly can be discarded and
the terminal assembly fitted directly into the elbow.
4.
In instances where the dimension " X" is between 250mm and
315mm it will be necessary to shorten the terminal assembly by
careful cutting to accommodate walls of these thicknesses.

1.
The straight rubber coupling will accept 21.5mm (
3
/
4
in) plastic
overflow pipe which should generally discharge internally into the
household drainage system. If this is not possible, discharge into
an outside drain is acceptable.
Important
The boiler condensate trap should be primed by pouring approxi
mately 300ml of water into the flue spigot. Do not allow any water
to fall into the air inlet.
See
Ensure the discharge of condensate complies with any national or
local regulations in force (see HHIC recommendations).
