5 October 2004 - Two New Research Reports by HSE, Dealing with Flueless Gas Fires
RR023 - Flueless gas fires – concentration of carbon monoxide, carbon dioxide, and nitrogen dioxide, and particulate level produced in use
In recent years, the supplementation of primary heating provided by central heating systems, by the use of fixed flueless gas fires, has substantially increased and are not at present covered by specific product or installation standards. They are, however, subject to certification by an independent Notified Body and must comply with the essential safety requirements of the Gas Appliances Directive (enacted by the Gas Appliances (Safety) Regulations 1995 (GASR)).
An assessment of the manufacturer's
installation instructions and the fires currently being installed to these
instructions is part of the Certification process.
The Health and Safety Executive (HSE), with support from the Department of
Trade and Industry (DTI), agree to sponsor the work of Advantica, in a bid
to encourage manufacturers to develop common product and installation
standards.

RR127 - Measurement and modelling of combustion products from flueless gas appliances
This report, by the Health and Safety
Executive (HSE), is on measurements and modelling of the combustion products
emitted from flueless gas appliances, of which the measurements made used a
range of appliances. The appliances' firing rates were variable and
completed within a controlled chamber. "Worst-case" simulations were
measured of extreme experiences within air-tight rooms. There were two
versions of ventilation used within the chamber, by means of a mechanical
ventilation system for controlled air exchange rates and purpose provided
vents in the chamber walls.
By using this type of ventilation, prediction of likely concentration of
combustion products, within room size and the potential use of flueless gas
appliances, provided a range of ventilation provisions.
The monitoring of the following was also included in the measurement: Carbon
dioxide (CO2) concentrations, carbon monoxide (CO), nitrogen dioxide (NO2),
nitric oxide (NO) and oxygen, with ultrafine particles, aldehydes and fuel
usage.
