SIDE FLUE - FLUE EXTENSION
Refer to Fig. 18.
The finished wall thickness plus (+) the distance from the
inside wall to the side of the white case plus (+) 30 mm will
give the length of the flue/terminal assembly required.
This length must not exceed 3 m.
If the length of the flue/terminal assembly is to be more than
500 mm, one, two or three flue extensions will have to be used
as follows:
1.
Carefully unpack the flue extension.
Supplied with the extension tube are three No.8 x 10 lg.
screws and a small roll of sealing tape.
2.
Locate the flared end of the extension over the open end
of the flue/terminal assembly as shown in Fig. 18. Ensure
that the inner flue tubes are engaged.
Fig. 18
3.
Using the pilot holes in the flared end of the extension, drill three 2.8 mm dia. holes into the outer tube of the
flue/terminal assembly. Take care not to damage the inner flue tube with the drill.
Secure the extension to the flue/terminal assembly using the three screws supplied with the extension. Seal the joint
with the tape supplied with the extension.
If the length of the flue/terminal assembly is to be more than 1500 mm fit another flue extension to the one just fitted in
the same way. Similarly if the assembly is to more than 2500 mm fit another flue extension.
4.
Mark the flue/terminal assembly to the required length, measure from the back of the terminal flange.
5.
With the cutting jig, supplied with the flue/terminal assembly, in position over the flue/terminal assembly as shown in
Fig. 17, cut the tubes to the correct length.
Using the cutting jig should ensure that the tubes are cut square.
6.
Clean up the edges of the cut tubes and discard the cutting jig.
