Installing a wood burning stove in a masonary chimney stack
Below is a general guide to the components commonly used for a wood burning stove installation in a fireplace with a masonry or stove chimney stack. We'll start at the stove end and work upwards:-
Generally, you will need to use vitreous enamel stove pipe from the stove to the stack itself. This is available with or without access doors for sweeping purposes. Many stoves can be swept through the stove by removing the internal baffle plate at the top of the burner.
Once you reach the stack itself, you need to decide if you need to line the chimney with a chimney liner or not. Also, if you are to line the stack, then you need to know the diameter of chimney liner you'll need. If you don't need a chimney liner, You'll need an adaptor to connect between the vitreous enamel stove pipe and the chimney liner. These are available as a standard adaptor or as an increasing adaptor if the liner is a larger diameter than the vitreous pipe.
You'll need to close off the bottom end of the chimney stack. This is done using Supalux which is a non-combustible fire resistant board capable of 240 minutes fire protection. It is made from calcium silicate reinforced with selected fibres and fillers and is available from most builders merchants. It comes in various sheet sizes and is easily cut to suit. Alternatively, we can get a stainless steel register plate manufactured to your dimensions. Please fax us a sketch to 01494 565386 or email a drawing and we'll return a price for you.
At the top end of the installation, there are various configurations for supporting the liner as shown below:-
Top Fixing Option 1
The Suspending Cowl is the one piece solution to fixing a chimney liner at the top end. It allows for the chimney liner to be installed without removing the chimney pot, and incorporates a stainless steel cowl section with a 1" mesh. The adaptor slides inside the top end of the chimney liner and the central shroud sits on top of the pot. Includes straps to attach the liner to the adaptor and also straps to attach the adaptor to the pot.
Top Fixing Option 2
If you would prefer to leave the top of your chimney stack open, then you can use a suspending adaptor, which also allows for the liner to be installed without removing the chimney pot.
Top Fixing Option 3
This method involves removing the chimney pot and supporting the liner at the top of the stack using the closure plate, top clamp and the top sleeve. The pot is then installed on top of these and the installation is completed using either the High Top Birdguard or a Birdguard.
