11.1 FLUE OPTIONS.

The standard flue length is from 127mm to 350mm measured from the appliance casing to the outer wall.

Extension flue kits, a vertical take-off adapter, 45¡ and 90¡ flue bends are available to increase the length and redirect the flue as follows.

Horizontal balanced flue:

a)From 127mm to 2500mm straight flue.

b)From 127mm to 1750mm when a 90¡ flue bend is required.

c)From 127mm to 1000mm when two 90¡ flue bends are required.

A 90¡ flue bend is equivalent to 750mm of straight flue. A 45¡ flue bend is equivalent to half a 90¡ bend.

Refer to Figs. 21 and 22 to determine whether extension kits, 90¡ flue bend, 45¡ flue bend, or adapters are required.

The maximum number of 90¡ flue bends allowed is two.
