Protect yourself from Carbon Monoxide

Using an appliance that is poorly maintained, incorrectly installed or using poor quality fuel will significantly increase the risk of the appliance producing carbon monoxide.
Only use appliances that fully comply with the current British Standards.
Have your appliance installed by a registered competent installer. Installers will ensure that the work carried out complies with the current Building Regulations.
Have your appliance regularly maintained by a HETAS registered engineer. Faulty appliances can lead to poor combustion which produces CO.
Burn the correct fuel for the appliance. De-ash the appliance as per manufacturers instructions. If the appliance burns wood, make sure the wood is seasoned and dry. Unseasoned wet wood suppresses combustion yet produces products of combustion which contain CO. If possible, use HETAS certified wood fuel, which guarantees a low moisture content.
Make sure your chimney is swept at frequent intervals. Use a HETAS approved chimney sweep. A blocked or restricted chimney will reduce flue performance, increasing the chances of the appliance spilling CO and other fumes into the property.
Make sure the appliance is set-up with sufficient combustion air to burn cleanly. Appliances with an incorrect fuel air mix can increase the rate of CO production.
Make sure there is enough fresh air in the room where the appliance is installed. Some appliances require a fresh air vent in the room where they are located. This is a permanently open vent to external air that must remain unblocked.
A responsible landlord should provide proof that a solid fuel appliance has been serviced and the chimney recently swept before the start of a tenancy. Thereafter, the ongoing maintenance of the appliance and chimney is subject to contractual conditions detailing responsibilities.
Carry out the user maintenance schedule as per the appliance ‘installation and us’ instructions.
