Measure the vertical distance between the top of the
fl ue (Fig.42) and the bottom of the fl ue
terminal assembly (Fig.41).
The measurements should be taken from the outer
diameter of the fl ue.
NOTE: Where this length does not match any stan-
dard combination of the extensions, extension can be
cut to the required length (Fig.44).
When cutting both inner and outer ducts of the extension,
always cut on spigot side, and they must be de-burred
Starting at the appliance end, assemble the extension
duct sections, making each inner and outer (fl ue) joint
by inserting the spigot end into the socket end of the next
tube, making sure the seal rings are correctly located (Fig
44). Make sure that the entire fl ue is adequately suppor-
ted. Use at least one bracket for each extension used.
Ensure that all inner fl ue connections have a good fi t/
seal, and that the space clips in each extension are
correctly positioned.
