Stove Installation
Before the stove is first used, refer to our Stove Operation page and the Operation Manual.
The below is a brief summary and is not intended to replace thorough reading of and strict adherence to all the relevant Building Regulations.
Stove Installation:
All of our stoves have a European style flue connection and will require an EU to UK converter flue pipe or adapter
DIY installations must be carried out according to the guidelines laid out in Building Regulations Approved Document J, 2010 - link below:
Read all the relevant sections (0,1 and 2) and appendices thoroughly!
You must inform your local Building Control office prior to installation.
Combustion Air requirement:
Stoves with a draught stabiliser fitted into the flue pipe, or stoves over 5kW will require a permanently open vent as per Building Regulations Table 1 Page 29 – “Other Appliances”.
An air vent in the wall near to the wood burner will prevent cold draughts travelling across the room and is highly recommended for all stoves.
Extractor fans must not be placed in the same room as the stove. Providing a a dedicated air supply to an extractor when a stove air inlet has a direct connection to the outdoors might be considered acceptable by some officials, as that is the norm in the rest of Europe.
Hearth Suitability:
Before installing the stove, you must ensure that the load-bearing capacity of the floor can withstand the weight of the stove plus flue pipe and connections.
Building Regulations Approved Document J, Pages 37- 39, Diagrams 24-27.
If the stove is placed on a combustible floor, the stove should always be installed on a non-combustible hearth. The hearth should extend 225mm in front of the stove and 150 mm to each side.
None of our products exceed 100ºc at hearth level. They may be placed on a 12mm non-constructional hearth directly onto the floor.
Distance of stove to adjacent walls, combustible, non-combustible:
The CE plate on the rear of the stove indicates the minimum distance to combustible surfaces to the back, sides, and to the front of the stove.
There is no requirement for minimum clearance to non-combustible surfaces around the sides and back of the stove. Convecting stoves already have sufficient gap for air flow built-in, but we would still recommend an inch or two.
For single wall stoves 100mm is recommended if possible to allow for air movement and heat from the stove to circulate. The further the stove is into the room, the heat circulation will be greater.
Refer to Diagram 30, Page 42 of Document J for further installation dimensions and requirements for non-combustible wall thickness etc.
Briefly:
There must be a minimum gap - as stated in the aplliances instructions and on the CE plate - between any stove and any combustible material e.g. curtains, furniture, plasterboard, wood. For single walled stoves usually around 450mm. Clearance for our convection sttoves are from 50mm up to 200mm. Please refer to the CE plate on the rear of the stove or the technical sheet for that model.
- Single wall stoves: if the stove is placed within 300mm of a wall, and sits on a hearth abutting a wall, then the wall must be non-combustible (usually brickwork or stone) to minimum heights of 300mm above the appliance and 1.2m above the hearth.
- There is a minimum gap required between an un-insulated flue pipe and other material. To a combustible material it must be at least 3 x the outside diameter of the flue pipe (450mm for 6” single wall flue pipe). To a non-combustible shield it must be at least 1.5 x the flue diameter (225mm for 6” single wall flue pipe). For insulated twin wall metal chimneys, this is reduced to 50 or 60 mm to combustible materials, refer to the product's installation sheet.
Some general points about Flue Pipes:
1. Flue to stove and flue pipe to twin wall chimney connections should be sealed with a suitable proprietary sealant such as fire cement and/or high temperature rope seal. Gunnable cartridge sealing compounds work well, and are easy to apply. We recommend and supply Fortafix products
2. If a suitable approved factory made twin wall chimney system is to be used it should be installed to the manufacturer’s instructions.
3. A Flue draught of 12 pascals is usually stated as teh minimum for the stove to run at its full potential. A chimney height of 4.5m should be adequate in most situations measured from the stove’s air outlet to the top of the chimney.
4. No horizontal runs are allowable.
5. Flues should have a maximum of 4 bends with angles of 45 degrees. And a maximum of two bends in-between each sweeping access point. [Page 27 Diagram 15].. The flue exit from the building should be positioned to comply with the requirements of the Building Regulations. These can be seen on page 31 Diagram 17.
6. If the chimney is too high (draught exceeds 35 Pa) or so that the chimney draught can be regulated on days with strong winds, it is necessary to fit the chimney or flue with a damper.
7. No other heating appliances should be connected to the same Flue or Chimney system.
Finally:
1. The Flue or Chimney must be unblocked, clean and sound (no leaks), and should be professionally inspected and swept before use.
2. Check the flue draught. This should be done with all windows and doors closed and any extraction fans in adjoining rooms running at maximum speed.
