Open-flued appliance
The Scottish Building Standards, Part I. Technical Handbook – Domestic, Appendix A Defined Terms, suggests that open-flued appliance: ‘…means one that draws its air for combustion from the room or internal space within which it is installed and uses a flue system to discharge its products of combustion to the outside air.’
Approved Document J, Combustion appliances and fuel storage systems, 2010 edition incorporating 2010, 2013 and 2022 amendments, defines an open-flued appliance as: ‘…one which draws its combustion air from the room or space within which it is installed and which requires a flue to discharge its products of combustion to the outside air.’
