Flue Extension
The total length must not exceed 3 m.
If the length of the flue/terminal assembly is to be more than 600 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 six 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. Ensure that the inner flue tubes
are engaged. If the length of the flue/terminal assembly is to be more than 1600 mm fit another flue extension to the
one just fitted in the same way. Similarly if the assembly is to more than 2600 mm fit another flue extension.
3.
Mark the final extension (extension that will connect to the boiler) to the required length, measure from the back of the
terminal flange. See Fig.21.
4.
Cut the last tube squarely to the correct length (the one that will fit to the boiler) and remove all burrs.
5.
Install the flue assembly in the wall, See Fig.21 & slide the support brackets on the extension & connect up to the flue
assembly. 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. Bend the end of the support bracket/s so it joins a wall or ceiling member &
secure with two screws/plugs provided.
6.
Return to the section you were at before this one and carry on with the installation.
