RR23 - Flueless gas fires - concentration of carbon monoxide, carbon dioxide, and nitrogen dioxide, and particulate level produced in use

The use of fixed flueless gas fires, to supplement primary heating provided by central heating systems, has increased substantially over recent years. Such fires are not presently covered by specific product or installation standards, but are subject to certification by an independent Notified Body against compliance with the essential safety requirements of the Gas Appliances Directive (enacted by the Gas Appliances (Safety) Regulations 1995 (GASR)). The Certification process includes an assessment of the manufacturer's installation instructions, and the fires are currently being installed to these instructions. Three manufacturers are currently offering a range of flueless fires, and their installation instructions are inconsistent with one another. They specify different requirements for fixed ventilation area and minimum room size, which are also below the minimum required by BS 5440: Part 2*1. In order to encourage the manufacturers to develop common product and installation standards, HSE (with support from the Department of Trade and Industry (DTI)) agreed to sponsor the work of Advantica, reported here.
