Once the boiler has been positioned on the wall, insert the elbow
into the socket (FIG 6.8) and rotate to the required position. NOTE:
It is possible to rotate the elbow 360
o
on its vertical axis.
Using the flue clamps , seals and scre ws supplied (FIG 6.8)
secure the elbow to the boiler.
The 1 metre horizontal flue kit (705958) supplied is suitable for an
exact X dimension of 823mm, and the 750mm horizontal

FLUE SYSTEM
The provision for satisfactory flue ter mination must be made in
accordance with BS 5440-1.
The appliance must be installed so that the flue ter minal is exposed
to outside air.
The terminal must not discharge into another room or space such
as an outhouse or lean-to.
It is important that the position of the ter minal allows a free pas-
sage of air across it at all times .
The terminal should be located with due regard f or the damage
or discolouration that might occur on b uildings in the vicinity and
consideration must be given to adjacent boundaries.
In cold or humid w eather water vapour may condense on lea ving the
flue terminal. The effect of such “pluming” must be considered.
If the ter minal is less than 2 metres abo ve a balcon y, above
ground or above a flat roof to which people ha ve access, then a
suitable terminal guard must be fitted. When ordering a terminal
guard, quote the appliance model number.
A suitable terminal guard is available from:

The minimum acceptable spacing from the ter minal to obstr uc-
tions and ventilation openings are specified in F
IG. 6.7.
IMPORTANT!
For all flue systems, a restrictor may need to be insert-
ed into the exhaust manifold, the size of the restrictor
and details of fitting requirements are sho wn in Table
6.1 (Page 18).
