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. 20).
2. Locate the flue elbow on the adaptor at the top of the
boiler. Set the elbow to the required orientation (Fig. 21).
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. 22).
4. To dimension 'X' add 50mm. This dimension to be
known as 'Y'.
IMPORTANT: Check all dimensions before cutting.
