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.
