Chimney flue liner kit FAQ

How do I fit a chimney flue ?

You'll need to either pull the liner up the stack or drop it down from the top. A length of rope and a nose cone are particularly helpful for this. You then need to connect the liner to the stove pipe at the bottom, and the chimney cowl at the top. See our flue liner installation guide for more details.

What size liner do I need in my log burner flue kit?

For appliances burning smokeless fuels, and with a rating of up to 20kw, minimum diameter of 5 inch (125mm) is required. For stoves between 20kw -30kw, 6 inch (150 mm diameter is required) Stoves that are DEFRA exempt and have a 5 inch (125mm) outlet, can safely use 5 inch diameter flue.

Which type do I need – 316 or 904 liner?

The difference is the thickness of steel used in the liner. 316 grade is fine for most wood burning stoves. For multi fuel stoves, you should use the higher grade 904 liner, as these appliances produce more acidic condensates.

How long will my flue liner last?

Our flue kits include chimney flue liners which come with a lifetime warrantly, guaranteeing them for as long as you own the property.
