Fitting The Flue
HORIZONTAL TELESCOPIC FLUE
1. There are tow telescopic sections. The Terminal
Assembly and the Connection Assembly, a roll of sealing
tape and two tapping screws . A 93˚ elbow is also
supplied. The outer duct of the Connection Assembly is painted
white On the Terminal Assembly The outer duct is unpainted.
2. The two sections can be adjusted to provide a length between
315mm and 500mm (Fig. 39) when measured from the flue elbow
(there is 50mm engagement into the elbow)
3. Locate the flue elbow on the adaptor at the top of the boiler
Set the elbow to required orientation (Fig. 41)
NOTE : The flue elbow is angled at 93 degrees to ensure a fall
back the boiler
4. Measure the distance from the outside wall face to the elbow.
This dimension will be known as 'X'
5. If the distance from the flue elbow to the outside face of the wall
('X' in ) is less than 250mm the Connection Assembly can
discarded and the Terminal Assembly fitted directly into the elbow.
6. 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 wills of these thickness.
7. To dimension 'X' add 50mm. This dimension to be known as 'Y'.
