Pellet stoves heat with a flame so safety is a major factor when determining the ideal location for installation.
Do you need a flue for a pellet stove.
The short answer is no.
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.
Using this example from afton bay pellet stove installation instructions i d guess that you need to be 12 from combustibles that would include pressure treated stairs.
Probably not most everything can be installed with a round liner with the exception of some liners for fireplaces.
Perfect for existing flues if you have an old fireplace that does not work or you want to reuse the existing flue in the home a pellet stove with an upper smoke outlet is ideal.
Larger is not necessarily better when it comes to your flue liner.
The size of the stove collar does not necessarily correspond to the size of flue liner you need.
For example there must be at least 1 inch of space from the back of the stove to.
Any problems must be remedied before continuing with the pellet stove installation process.
The general rule is as follows.
Example pellet stove fire and exhaust vent clearances.
For a stove of up to 20kw a minimum of 6 diameter flue is needed.
Chimney fires are a real and present danger any time a heat source vents through the flue.
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.
Too large will give you a slow draft and poor performance and too small will restrict the draft.
You can use a 5 diameter flue liner if you have a defra approved stove and the manufacturer clearly states this is compatible.
The flue is a single wall or insulated flue that rises up fixed to the outside of the building or up through the chimney so that smoke can escape.
Call a chimney inspector to evaluate the inside of your chimney for excess creosote buildup and structural defects.
Follow manufacturer s installation requirements specific to your pellet stove.
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.
