Too large will give you a slow draft and poor performance and too small will restrict the draft. For example there must be at least 1 inch of space from the back of the stove to. You can use a 5 diameter flue liner if you have a defra approved stove and the manufacturer clearly states this is compatible. The smoke fitting which in the case of the pellets has a reduced diameter only 8 centimetres can be inserted directly into the existing flue.

For most stoves you will need to plan for a 3 inch flue to exit out the back or top of the stove go through the wall and then extend upward past the house eaves. Traditional wood log stoves and burners are positioned inside a fireplace with chimney or against an outside wall of the room with a direct route for a flue to reach the top of the property.
