Installing The Standard Flue - The Fire Brick D130 Instruction Booklet

42
If you've built your oven outdoors and the flue will be well clear of any combustible materials as per the diagram
on page 9, you can install the standard flue for the oven following the steps detailed below.
8A: INSTALL THE FLUE
Place the flue cowling (hat) on the plain end of the
flue pipe, this is meant to be a snug, tight fit.
Now, fit the crimped end of the flue pipe section into
the stainless steel sleeve protruding from the flue
Gallery. Remove the plastic film from the stainless
steel ring that covers the flue expansion joint.
8B: SECURE PIPE FOR WINDY AREAS
The flue is quite stable with only one length but if
you live in a particularly windy area you may want
to secure your flue using stainless steel screws or
pop rivets (screws if you intend to remove the flue in
future). With either method you will have to pre-drill
the holes.
If you use three screws/rivets at equal spacing around
the flue, this will be sufficient to hold it level.
If your installation involves anything more complex than the basic setup that we provide in the
kit, you must engage a suitably qualified plumber to supply and install the flue for you. Your
local fireplace store should have several professionals they can recommend. Your oven can
reach extreme temperatures, to the point where the flue glows orange.
This is important, if you go down the path of installing your own flue system and somehow, your oven causes
a catastrophic fire, 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 flue - let's say you wanted it black, for example. Don't try to paint
the stainless steel flue - there is no paint available that can withstand the full range of temperature that this
flue can reach. Rather, get a 'twin-skin' flue system, and have the external flue 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 flue pipes
together at the top. These flue systems and other, more complex flues are available at good plumbing supply
stores, and most wood heater retailers. Your plumber will source these components for you.
The flue should be installed whenever the oven is fired. Without the flue, most of the smoke will come out of the
oven mouth and cover your brickwork with soot. Leave the flue 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).
