8. Installing the Standard Flue
9A: INSTALL THE FLUE
Place the ue cowling (hat) on the plain end of the
ue pipe, this is meant to be a snug, tight t.
Now, t the crimped end of the ue pipe section into
the stainless steel sleeve protruding from the ue
Gallery. Remove the plastic lm from the stainless
steel ring that covers the ue expansion joint.
9B: SECURE PIPE FOR WINDY AREAS
The ue is quite stable with only one length but if
you live in a particularly windy area you may want
to secure your ue using stainless steel screws or
pop rivets (screws if you intend to remove the ue in
future). With either method you will have to pre-drill
the holes.
If you use three screws/rivets at equal spacing around
the ue, this will be sucient to hold it level.
If you’ve built your oven outdoors and the ue will be well clear of any combustible materials as per the diagram
on page 9, you can install the standard ue for the oven following the steps detailed below.
This is important, if you go down the path of installing your own ue system and somehow, your oven causes
a catastrophic re, your home insurance may be null and void. Put this in the same category as working with
high voltage electricity - the risks massively outweigh the rewards. Don’t risk it, use a licensed plumber.
You may want to change the colour of the ue - let’s say you wanted it black, for example. Don’t try to paint
the stainless steel ue - there is no paint available that can withstand the full range of temperature that this
ue can reach. Rather, get a ‘twin-skin’ ue system, and have the external ue pipe (the second ‘skin’) painted
in a high temp coating. This will also require you to purchase a ‘twin-skin’ cowling to lock the two ue pipes
together at the top. These ue systems and other, more complex ues are available at good plumbing supply
stores, and most wood heater retailers. Your plumber will source these components for you.
The ue should be installed whenever the oven is red. Without the ue, most of the smoke will come out of the
oven mouth and cover your brickwork with soot. Leave the ue installed unless the oven is being covered for a
long period of time (eg. to protect the oven from freeze-thaw during winter in a very cold climate).
If your installation involves anything more complex than the basic setup that we provide in
the kit, you must engage a suitably qualied plumber to supply and install the ue for you.
Your local replace store will have several professionals they can recommend. Your oven can
reach extreme temperatures, to the point where the ue glows orange.
