How to fit a cassette wood burning stove
This was actually two large cassette stoves back to back replacing a large open fireplace that could be viewed from two sides of a central column in the room. The original large open fireplace actually decanted its smoke into two brick flues. I think this would be a difficult job for anybody other than a very competent DIY’er or a tradesman.
The job took two of us six days, the chimney being 12 metres high and the chimney liner was 6″.
When I first went to see the job I almost turned it down. They were two very large stoves and all I could see at that stage was a large sooty fireplace. Above the fireplace was a heavy metal funnel taking smoke into one of the two flues. Everything was very sooty.
Things improved when the householder had a local guy sweep the chimney and remove the metalwork. Note that hsi work and our work was all done without removing the customers fitted beige carpets. “Never again” said my stressed assistant.
In the end this was a very satisfying job and the customer was very happy with the outcome.
One side of the opening. Note we are replacing the metal bar lintel with a concrete lintel. We raised the concrete lintel nice and high as we needed to fit a 45 degree elbow to the top of the stove to allow the liner to come in at an angle.
Other side of same recess. In this case we were very lucky to have found an insert of the correct width – lots of web searching and some luck!
Here you can see a liner dangling in the recess from above.
The insert is in the metal surround and liner attached via an adaptor to the elbow (everything screwed together with metal to metal self tappers so nothing can come apart even if it meets a bad tempered sweep).
We just used normal plaster (customer wallpapering afterwards)
Elbow firmly screwed into place with fire rope into small gap.
Stove installation instructions requested a 1cm gap around box
Suspended floor allowed for floor air vents
Frame added after wall papering completed
And another one
