8.0INSTALLATION
8.6Condensate 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 (3/4in) 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.
8.7Fitting 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. 23).
2.Locate the flue elbow on the adaptor at the top of the boiler. Set the elbow to the required orientation (Fig. 24).
NOTE: The flue elbow is angled at 93 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. 25).
4.To dimension ‘X’ add 50mm. This dimension to be known as ‘Y’.
IMPORTANT: Check all dimensions before cutting.
