7.10 Standard Flue Dimensions
The standard horizontal flue kit allows for flue lengths
between 270mm and 800mm from elbow to terminal
(Fig. 18).
The maximum permissible equivalent concentric flue
length is: 4 metres (Fig. 18a).
NOTE: Each additional 45° flue bend will account
for an equivalent flue length of 0.5m.
eg. 45° = 0.5m, 93° = 2 x 45° = 1m etc.
7.11 Terminal Guard (Fig. 19)
1. When codes of practice dictate the use of terminal
guards, they can be obtained from most Plumbers’ and
Builders’ Merchants.
2. When ordering a terminal guard, quote the boiler
model name and type. Tower Flue Components
(Tel. 01732 351555) part no. CGDK6BR is suitable.
3. There must be a clearance of at least 50mm
between any part of the terminal and the guard. The
guard should be positioned centrally over the terminal
and fixed as illustrated.
4. The guard must be of a non - corrosive material
(e.g. stainless steel) or plastic coated.
