DEFRA Approved with a 5" Outlet
Most stoves have a 6" outlet and therefore require a 6" liner. Problems occur when the existing chimney has a narrow flue - sometimes a liner just won't fit!
Not all is lost though... Some stoves have a 5" outlet and have been approved by DEFRA meaning that they can be installed with a 5" liner. Below is a selection of just such stoves.
If sourcing your own stove, it's important to note that not all stoves with a 5" outlet are DEFRA approved. If in doubt, avoid a costly mistake and check with a member first.
