Flexible flue liner

[Backboiler]

I have been asked to do a quote on fitting a ss flexible flue liner in an existing chimney but I have never done one or been shown how to fit one. Customer is wanting a gas stove. How difficult a job is it. Can anyone give me a few pointers or post a good link please?

liners are generally easy to drop,getting on the roofs the hard bit i use a roofer normally roofer goes up top chucks a weighted cord down attached to the liner between you and him you pull it down to wherever you need it he does his bit on top you terminate the appliance end

It's not that difficult really.
The hardest bit is being on top of a chimney is fluctuating wind directions with 15m of 5 inch liner fighting you every inch of the way.
Definitely a young mans game.
Eventually I realised the folly and subbed the jobs out to a roofer, I supplied the liner kit and supervised from below.

I understand you can buy a kit with the liner and accessories but it only has one clamp plate. I realise you have fit the clamp plate at the bottom but how is it secured at the top? and do you leave the top entirely to the roofer? Does he/her fix it, flaunch it and fit the terminal?

the clamp plate if for the top, you have to fit the clamp, terminal and flaunch it with sand and cement yourself which is easy and will require approx one to two 3/4 buckets of sand and cement. you may require a register plate and adaptor at the bottom of the liner. the stove will probably have a starter pipe as liner can not be left on show outside of the chimney void.

you will likey need the appliances instructions to quote the materials.

the clamp secures it to the top not the bottom,you have to make up the bottom part,the BES catalogue is a good way to get what you need and cheaper than most can you post up the proposed appliance your fitting and what are you doing up top? brick chimney or IL

In my defence, I must admit I take backboilers out not install them

Liners are really easy to drop without a rope or someone pulling it. Put a slight kick about 6" from the end and drop it. When you hit the bends, spin the liner and it will go past.
Takes 2 minutes to drop if it is raining or 20 minutes if it is a nice day :smile:
