Six Aspects of Wood Burning Stoves Installation
The chimney must be fitted in accordance with manufacturer's instructions and the relevant part of the Building Regulations. The chimney height and the position of the chimney terminal should conform to Building Regulations and all local regulations, including those referring to national and European standards.
The chimney must be in good condition, and any cracks and obstructions are not permitted. The diameter of the flue should not be less than 125mm and not more than 200mm. If any of these requirements are not met, the chimney should be lined by a suitable method.
The chimney must be swept before connection to the stove. We also recommend that the chimney be swept a second time within a month of regular use after installation.
If you have any doubts about the suitability of your chimney, consult a local installer.
A flue draught of minimum 1.2mm to a maximum 2.5mm water gauge may keep the appliance in good performance. If the flue draught exceeds 2.5mm, a draught stabilizer must be installed in order to control the rate of burning and prevent overfire. You should check the flue draught when fire is on high output.
You should brick up or seal an existing fireplace opening with a register plate. A short length of flue pipe of a minimum 125mm internal diameter may then be used to connect the stove to the chimney. This flue pipe should conform to Building Regulations. Ensure that the pipe end is no closer than 76mm to the side or rear chimney walls.
Ideally, the old fireplace should be filled in so that there is a smooth streamlined entry into the flue way.
The length of any horizontal run of flue pipe must not exceed 125mm.
It is essential that all connections between the stove and chimney-flue are sealed and made airtight.
This appliance is not suitable for installation in a shared flue system.
Both the chimney and flue pipe must be accessible for cleaning and if any parts of the chimney cannot be reached through the stove (with baffle removed), a soot door must be fitted in a suitable position to enable this to be done.
A permanent, unobstructed air opening is essential for the room or space containing this appliance. The air opening should be at least 3625m㎡ when a draught stabilizer is equipped. Due care for air requirements will need to be taken if any other appliances are permitted to work in the same room and space.
It is workable for the appliance to be recessed in a prepared fireplace, but a suitable free air gap (minimum 150mm) must be left around the sides and top and at least 50mm at the back of the appliance to reach maximum heat output and for access to the rear of the stove. All non-combustible walls closer than 300mm to the stove should be at least 75mm thick.
In all instances the back wall of the fireplace recess and the hearth should be made of non-combustible material. Allow an apron of at least 300mm at the front of the stove and 150mm on either side.
The hearth on which the stove is to be placed should not be less than 125mm thick and should be in accordance with the current building regulations.
Care should be taken to level the stove using the adjusting screws in the feet.
The appliance shall be installed on a floor with adequate load-bearing capacity. If the existing construction does not meet this prerequisite, suitable measures(e.g. load disturbing plate) should be taken to achieve it.
There should be no combustible material within a distance of 500mm from any surface of the stove.
Commissioning and Handover
You should leave an appropriate period of time for fire cement and mortar to dry out upon completion of the installation. In order to ensure the smoke and fumes are taken from the stove up the chimney and emitted safely to atmosphere, a small fire should be lit first. Do not run the stove at full output for at least 24 hours.
Finishing the installation and commissioning, the operating instructions and tools for your stoves should be kept in hand. It is also important to know how to use the stove properly and use only the recommend fuels for this appliance. The user should know how to have smoke or fumes emitted properly form the stove and be warned to prevent injuries in case of the presence of children, aged or infirm persons.
