10.6 Condensate Drain (see section 7.6)
1. Connect the condensate drain using the 1” BSP nut
and seal supplied.
Ensure the discharge of condensate complies with
any national or local regulations in force (see British
Gas “Guidance Notes for the Installation of
Domestic Gas Condensing Boilers”.
2. The condensate outlet terminates in a 1” BSP nut and
seal for the connection of 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.
10.7 Fitting The Flue
HORIZONTAL FLUE
1. The standard flue is suitable for lengths between
100mm minimum and 685mm maximum, as measured
from the edge of the flue elbow outlet to the joint
between the terminal and air duct (Fig. 34).
2. Locate the flue elbow on the adaptor at the top of
the boiler. Set the elbow to the required orientation
(Fig. 35).
NOTE: The flue elbow is angled at 91.5 degrees to
ensure a fall back to the boiler.
3. Measure the distance from the outside wall face to
the elbow. This dimension will be known as ‘X’ (Fig. 36).
4. To dimension ‘X’ add 50mm. This dimension to be
known as ‘Y’.
IMPORTANT: Check all dimensions before cutting.
