The incorrect installation of a heating appliance or design and installation of a flue can result in situations leading directly to the dangers noted above. The installation of mechanical extract fans is not in itself dangerous but guidance on their use has been included under this standard as their use with open-flued appliances can cause problems.

Extract fans lower the pressure in a building and this can cause the spillage of combustion products from open-flued appliances. This can occur even if the appliance and the fan are in different rooms. Combustion appliances therefore should be capable of operating safely whether or not any fan is running see clause 3. Biomass as a solid fuel comes in different forms with the most common being woody biomass. Wood burning appliance technologies are such that modern appliances are now designed to efficiently burn specific wood fuel types including logs, wood chips, wood pellets and wood thinnings.

Guidance that is given for solid fuel appliance installations may also be appropriate for biomass appliance installations however, depending on the complexity of the system there may additional issues to consider particularly in relation to safety, noise, flue sizing, ventilation and fuel storage.

There is other legislation that relates to gas fittings, appliances, installations and their maintenance and to the competency of persons who undertake such work see clause 3. Conversions - in the case of conversions , as specified in regulation 4, the building as converted shall meet the requirement of this standard regulation 12, schedule 6.

The guidance also includes flueless appliances such as gas cookers. The guidance to Standards 3. A few large dwellings may require such installations. The following guidance therefore, may not be relevant to solid fuel appliances with an output rating more than 50kW, oil-firing appliances with an output rating more than 45kW and gas-fired appliances with a net input rating more than 70kW.

Where a combustion appliance installation is intended to operate with more than one type of fuel, for example a gas appliance as a stand-by to a solid fuel appliance, each component should be constructed and installed to meet the most onerous requirement of the relevant fuel.

Installations should be constructed and installed in accordance with the requirements of BS Parts 1 to 3: Wood pellet burning stoves and boilers are generally designed and constructed with high levels of automation, to be very efficient and with low emissions. Wood pellet burning appliances can appear similar to other wood fuelled appliances however they are normally designed and manufactured specifically for the combustion of wood pellets fuels only.

Heating Boilers with Forced Draught Burners. The Heating Equipment Testing and Approval Scheme HETAS is an independent organisation for setting standards of safety, efficiency and performance for testing and approval of solid fuels, solid mineral fuel and wood burning appliances and associated equipment and services for the UK solid fuel domestic heating industry. It operates a registration scheme for competent Engineers and Companies working in the domestic solid fuel market.

There are other organisations representing the solid fuel industry but neither they nor HETAS have a mandatory status. It publishes technical guidance, operates a registration scheme for competent technicians and companies and an equipment testing and approval scheme.

OFTEC schemes and technical advice only have mandatory status when specifically referred to in legislation. Oil-firing appliances should be constructed , installed, commissioned and serviced carefully to ensure that the entire installation operates safely. Oil-firing equipment should be suitable for its purpose and the class of oil used in the installation.

Oil-firing equipment should comply with the relevant OFTEC standard and should be installed in accordance with the recommendations in BS Parts 1 and 2. Fire valves should be fitted so as to cut off the supply of oil remotely from the combustion appliance in the event of a fire starting in or around the appliance. The valve should be located externally to the dwelling.

The valve should be fitted in accordance with the recommendations in Section 8. These regulations require that, amongst others, gas-fired installations are installed by a competent person.

The Gas Safety Installations and Use Regulations regulates gas installations while the Gas Appliance Safety Regulations address the product safety of appliances. This also applies to cases where a flue liner is provided as part of refurbishment work.

The labels should be indelibly marked and contain the following information: the location of the hearth, fireplace or flue box or the location of the beginning of the flue a chimney designation string in accordance with BS EN see clause 3.

Labels should be located in a position that will not easily be obscured such as adjacent to: the gas or electricity meter, or the water supply stopcock, or the chimney or hearth described. Safety Label 3. Ceiling fans produce currents and hence local depressurisation that can also cause the spillage of flue gases.

The presence of some fans may be obvious, such as those on view in kitchens , but others may be less obvious. Fans installed in appliances such as tumble dryers or other open- flued combustion appliances can also contribute to depressurisation. Fans may also be provided to draw radon gas out of the under building. In dwellings where it is intended to install open- flued combustion appliances and extract fans, the combustion appliances should be able to operate safely whether or not the fans are running.

The installation of extract fans should be in accordance with the guidance below, and should be tested to show that combustion appliances operate safely whether or not fans are running: for solid fuel appliances, extract ventilation should not generally be installed in the same room or alternatively seek further guidance from HETAS. To check for safe operation of the appliance s the recommendations in clause 5.

What are the base requirements for Storage Tanks? As a minimum, all plastic oil tanks should be installed on a flat, level, fire resistant surface, capable of supporting the weight of the tank when fully laden. The base should extend at least mm beyond the widest points of the oil tank and fully support the base of the oil tank in its entirety. On plastic tanks, piers are not suitable for this purpose and will cause irreparable damage to the oil tank, possibly resulting in premature failure and catstrophic product loss.
