Wood burning and Multi-fuel Made Easy – Vol. 2

In the second of our series of ‘Made Easy’ blogs, we’ll be explaining terms that will crop up before and during your fire or stove installation. These are all things that need to be considered, but we’ll explain some of the key areas and take away some of the mystery behind some of the topics you’re likely to come across.

12mm Hearth Installations

If you’re installing your stove into a room without a chimney or fireplace, you need to ensure your chosen appliance sits on a hearth with a minimum depth of 12mm. Stoves available from Stovax have been tested to ensure that they do not increase the temperature of the floor to more than 100°C.

It is essential to have a 12mm hearth placed below the stove to allow a safe distance to combustible materials to be maintained. Stovax have a wide range of stoves and fires that are suitable for 12mm hearth installations.

Superimposed Hearth

A superimposed hearth is basically a term for a hearth that is slightly above normal floor level. Often referred to as a ‘decorative’ hearth, it can be made from slate, tiles or granite having a minimum thickness of 12mm (see above).

Constructional Hearth

A constructional hearth is usually built at the same time as the house. Usually built in concrete with a depth of 125mm, the constructional hearth will extend underneath the superimposed (decorative) hearth that sits on top of it. A constructional hearth is required if your chosen freestanding fire or stove increases the floor temperature to over 100°C.

Distance to Combustibles

One of the main points to remember before a stove or fire installation is the distance between the appliance and combustible materials, AKA ‘distance to combustibles’. It’s imperative that a safe distance is left between any flammable materials such as wood or wood products, plaster board, soft furnishings and materials or anything that could potentially burn.

This ‘distance to combustibles’ is required to ensure there is enough space above, below and around the appliance to maintain safe operation and for easy access to carry out any routine maintenance.

Site Surveys

This isn’t quite as daunting as it sounds. Before you purchase your chosen appliance, we recommend the survey by a qualified engineer to fully establish the suitability of your home. During the site survey, your retailer will consider the appropriate heat output for the room, the location of the appliance, whether a flue system is required, ventilation and distance to combustibles.

Stovax Site Survey

Another very important reason to complete a site survey is that it will identify the most suitable appliance for the location of your home. Many areas, such as towns and cities, are designated Smoke Control Areas—if this is the case for you, you’ll need to consider Smoke Control Exempt appliances.

Don’t worry, there is a wide range of Smoke Control Exempt appliances from Stovax if you do live in these areas, and your retailer will be able to give you more information on this.


Once your appliance is fitted, your installer is obligated to leave their details together with the appliance commissioning checklist.

Stovax Commissioning

The checklist is within your user manual that is supplied with the stove or fire and should be completed by the installer. The document contains all the info required about your stove (such as model and serial number), together with a list of commissioning checks. You should retain this for future use.

If you intend to make use of the extended warranty available for your stove, it is condition that the commissioning form is complete.

Serial Numbers

Each fire and stove has its own unique serial number which can be found on the appliance’s data plate. The location of the data plate does differ from appliance to appliance, but your user manual will tell you the exact location for yours.

Your serial number is required if you ever need to order any spare parts or make warranty claims. Together with your installers name, date of installation and full model name, the serial number is required should you require assistance from our Technical department.

For further information on any of these topics, please contact your nearest retailer.
