Installing a stove in a chimney

With a wood burning stove or multifuel stove, 75% of the heat goes out into the room, with an open fire 75% of the heat goes up the chimney, this means that the smoke from a wood burner or multi fuel burner is cooler than that from an open fireplace. This can lead to the stove not drawing properly and therefore the cooling smoke will condense creating soot and tar deposits. Tar deposits cannot be removed by a sweep's brush and can in some cases cause a chimney fire; you may get tarry condensate leaking out and sometimes even through the joints of the chimney. For this reason it is recommended that you line and insulate a chimney whenever you fit a wood burning stove.

Do I have to hire someone to do the work?

Lining a chimney for a wood burner falls under building control, however it’s not a complicated job and can be done by a competent DIY enthusiast. However, you must inform your local building control department of the work you do; they will inspect the job once it has been completed and make sure it is up to standard.

Fitting a wood burning stove into an existing fireplace

Building regulations require that the wood burning stove should be placed on a plinth of non-combustible material extending at least 150mm at the sides and 300mm in the front.

To fit the wood burner into a fireplace you will need:

A chimney register plate (click here). This is the plate used to seal off the opening of the fireplace and has a hole for the flue pipe, an access panel and if needed a bracket to support the flue. The single wall flue pipe (click here) is needed to go from the stove to the register plate. Flexible flue liner (click here) fixings and fire cement (click here).

Tools that are required to install a chimney liner

There are no specialist tools needed to fit a flexible chimney liner for wood burning stoves, however you will need to access the top of the chimney stack using roof ladders or preferably from a safety standpoint, scaffolding. It is highly recommended by Stoves Etc that you use a harnesses when working at a height, other safety equipment you should use during the install are masks, goggles and gloves.

Installing the Stoves Etc flexible flue liner

Stoves Etc have set up a list of step to take to install a flue liner into your chimney

1. Before you start installing the liner the chimney must be swept and inspected for faults and the area around the wood burning stove should be protected from debris and dust.

2. If you are using a chimney pot hanging cowl you can skip over this step, otherwise you will need to remove the chimney pot and mortar on top of the chimney stack.

3. Cut the register plate to fit your chimney (our register plates are cutable), fix the angle iron in place.

4. You will need a piece of regular rope 5 meters longer than the liner you are using. Tie a weight to the rope and lower it down the chimney.

5. Attach a nose cone to the bottom of the liner (the liner is directional, arrows pointing upwards) if you are using Rockwool, attach this to the liner.

6. Tie the rope to the nose cone and then lower the liner down the chimney; if there are bends in the chimney you are installing your stove into and the liner gets stuck inside it, some wiggling of the rope line should be sufficient to free the flue liner and navigate the bend.

7. Once the chimney flue liner has been lowered down and is in place, connect the chimney liner to the single wall flue pipe to flue liner adapter using self-tapping screws. Fit the stove pipe in place attached to the liner and now fit the register plate sliding the pipe into the hole on the plate and securing the register plate in place on the frame. Put the stove in place and seal around the register plate and the single wall flue pipe with fire cement.

8. If you have pre-insulated the flexible flue liner we recommend that you drop from the top of the chimney an adequate amount of vermiculite insulation (click here) above the register plate; this is to stop the heat escaping into the chimney void (the space between the register plate and the stove). This should be done before installing the top plate.

9. Cut the liner to length and fit the top plate, the insert and then the top clamp.

10. If you have a chimney pot hanging cowl you will need to cut the flexible flue liner to length and then attach the cowl to the chimney liner using the fixing straps provided, insert the cowl into the chimney pot and attach using the straps provided. Afterwards, re-fit the chimney pot.

11. Stoves Etc recommend that you leave 34 hours before the install and the first smoke test.

There you go. Your new Stoves Etc stove is ready to start burning. If you want to clarify any of the steps involved or require any more information feel free to contact us and talk to one of our advisors click here .
