Figure 11 ATTACHING AIR BOX
The flue system provided with the boiler is telescopic and
can be adjusted to suit wall thicknesses of 230mm-380mm
(9in-l5in). Wall thicknesses down to 76mm (3 in)are catered
for by shortening the Air Box, Inner Flue Product Tube (see
Figs 11 & 14), the Air Tube and Outer Flue Product Tube
(see Figs 13 & 15). Each tube is to be shortened at its plain
end by the amount shown in the following table.
For wall thicknesses between 100mm-
175mm (4in-7in), the alternative telescopic
Flue Kit can be used for additional convenience.
Using the packaging material to protect the boiler from
damage, lay the boiler on its side and secure the Air Box to
the boiler using the nine M4 screws from accessory pack
B. Engage adjustment screws into the boiler legs but do
not screw in fully at this stage.
