The Charnwood Vertical Rear Flue Adaptor is a genuine Charnwood stove accessory designed to allow a compatible stove to connect from the rear while directing the flue vertically upwards.
This arrangement allows the stove to be positioned further forward into the room and away from the wall behind, providing greater flexibility when planning a stove and chimney installation.
Depending on the stove model, fitting the vertical rear flue adaptor increases the overall depth of the appliance by approximately 115mm to 196mm.
What Is a Vertical Rear Flue Adaptor For?
A vertical rear flue adaptor is useful where you want the flue connection to leave the rear of the stove but then continue vertically upwards.
It can help provide additional clearance behind the appliance, accommodate an existing chimney or flue position, or simply allow the stove to sit further forward within a fireplace opening.

This should be taken into account when planning the position of the stove, hearth, fireplace opening and surrounding clearances.
