What is BS EN 613 - Closed-fronted gas-fired heaters about?
BS EN 613 is a standard that covers closed-fronted gas-fired heaters, enabling efficiency and performance in energy applications.
BS EN 613 specifies the requirements and test methods for the construction, safety, marking and rational use of energy.
BS EN 613 is applicable to types B11AS, B11BS, B11CS, C11, C31 and C91 appliances and those that:
- Are closed-fronted
- Incorporate a natural draught burner
- Are connected directly to an open flue or to a device to evacuate the products of combustion open-flued appliances, balanced-flued appliances)
- Are wall-mounted, free-standing or built-in
- Have a nominal heat input not exceeding 20 Closed-fronted gas-fired heaters (based on the net calorific value)
Note 1: BS EN 613 is not applicable to:
- Open fronted appliances as specified in EN 13278:2013
- Decorative fuel effect appliances as specified in EN 509:1999/A1:2003
- Catalytic combustion appliances
- Appliances in which the supply of combustion air and/or evacuation of products of combustion is achieved by mechanical means as specified in EN 1266:2002
- Ducted-air appliances
- Appliances installed by means of a closure plate
Note 2: Matters related to quality assurance systems, tests during production and to certificates of conformity of auxiliary devices are not dealt with by BS EN 613.
Who is BS EN 613 - Closed-fronted gas-fired heaters for?
BS EN 613 on closed-fronted gas-fired heaters applies to:
- Manufacturers of gas-fired heaters
- Dealers and importers of gas-fired heaters
- Testing houses and labs for gas-fired heaters
- Quality assurance services
- Regulatory bodies
Why should you use BS EN 613 - Closed-fronted gas-fired heaters?
Closed-fronted appliances are appliances that do not have exposed flames or exposed incandescent areas. A forced gas-fired heater is an appliance that incorporates a fan and thus allows an acceleration of the circulation of the air in contact with the heating body.
BS EN 613 provides users guidance on the classification of appliances depending on the nature of gases used and the method of evacuation of the products of combustion, enabling the proper identification and classification of closed fronted gas-fired heaters
BS EN 613 provides users guidance on constructional requirements, including general requirements, adjusting, control and safety devices, ignition burner, flame supervision systems, burners and gas pressure test points, ensuring stable operability and functioning of gas-fired heaters.
With obedience and compliance to BS EN 613, users can develop and assess gas-fired heaters, ensuring operational stability, efficiency and performance in energy applications.
