What is needed to install my woodburner?
Below you will find the products needed to install a stove into a property without a chimney system. This system is based on the pipe coming out the top of the stove and straight up and out through a roof. If you want to come off the back of the stove and out through and external wall and then up the side of the property please read the following Step by step guide to installing and external twinwall chimney system.

When installing you stove you must follow the following guidelines:
Once your stove is into position you must decide whether you would like to use Single skin stove pipe to come out from the top of the stove or if you would like to use Twinwall insulated pipe all the way.
If you want to use Matt black single skin pipe directly out of the top of the stove then you must ensure that the stove pipe is a distance of at least 3 times its diameter away from any combustible materials (For example if your using a 5" flue it would need to be at least 15" away from a combustible)- If you are using Twinwall pipe then it would only need to be at least 2.5" (65mm) away from any combustible materials.
If you do decide to use Single skin pipe first then you must ensure that the double insulated pipe comes into the room by at least 6" (150mm), In other words the single skin pipe must stop at least 6"-7" below the ceiling.
If you however decide to use double insulated all the way then you would use the Twinwall Adapter in the stove and run the double skin pipe all the way.
It is required that you use a support bracket at least every 2 meters tp provide adequite support to the pipe.
When the insulated pipe comes out through the roof of the property there are 2 guidlines you must follow:
a) If you come out close to the ridge you need to ensure that the pipe clears the ridge by at least 600mm
b) if coming out through the roof in another area away from the ridge then the flue must be at least 2300mm horizontally from the nearest point on the weather surface AND at least 1000mm above the highest point of intersection of the chimney and the weather surface OR at least as high as the ridge. |
