Multifuel stove installation

[Anonymous]

We are plannig to install our multifuel stove using the rear flue option, with a 90 degree bend to connect to the vertical stove pipe. The stove pipe has a soot door in it. I've now read somewhere that 90 degree bends should be avoided as they will inhibit the flow of the flue and that if you must install one, it should have a soot door. The argument is that a soot door on a vertical pipe is useless because the sweep won't be able to brush through it.

Grateful for any advice and experience out there on this - I wonder, if they are of no use or shouldn't be used, why you can buy the 90 degree bend and stove pipe with soot door? Also, if you can't sweep through the soot door on a vertical pipe, how can you sweep through such a door on a 90 degree bend which is only inches from the floor?

There are a couple of main points you need to look at:

You need some way of clearing the soot that will build up at the bottom of the 90 degree bend. Soot can build up, reducing the effective size of the flue pipe, making the stove unsafe. The best flue pipe to use is a 90 degree tee – this has a short extension at the bottom allowing for a slight soot build up and it also has an easily removable cap (no fiddly screws).

Are you lining your chimney? If so, you will need an access through one of your flue pipes as that will be your only access. Your sweep will only need a small brush head and should have rods flexible enough to sweep through the pipe and up the liner.

If you are not lining the chimney, you will need an access through the register plate used to seal off the bottom of the chimney so that you can clear the soot build up on the board as it could increase the risk of a chimney fire. This will then also act as a sweeping access for the rest of the chimney.

There are no problems in using a 90 degree bend providing it is used straight off the back of the stove (no extra horizontal flue) and there are no more than two additional 45 degree flue pipes in the installation.

I have followed the link, but I can't find any information on the website other than stove sales...

Me, too.

Sorry - I wasn't intending to direct you to the website, just offering some advice, although we do sell stove flue pipe. Apologies for the confusion.
