What is BS EN 14543-Parasol patio heaters about?
BS EN 14543 discusses parasol patio heaters. BS EN 14543 specifies the design, safety, and marking requirements and test methods for flueless patio heaters for outdoor or amply ventilated area use only.
These appliances are for use exclusively with gases of the third family. BS EN 14543 applies to appliances that have a nominal heat input not exceeding 17 kW (based on the gross calorific value), supplied with a maximum inlet pressure of 50 mbar fixed or, movable, including those which comprise a housing for a transportable and rechargeable liquefied petroleum gas cylinder.
Note 1: BS EN 14543 does not apply to appliances equipped with a fan for either combustion or circulation of the convection air.
Note 2: BS EN 14543 does not cover LPG containers for liquefied petroleum gas, their associated regulator, tubing, and flexible hoses used for gas supply of appliances covered by BS EN 14543. Regulator, tubing, and flexible hoses are covered by other standards (EN 16129, EN 16436-1 and prEN 16436-2, etc.) and national regulations
Who is BS EN 14543-Parasol patio heaters for?
BS EN 14543 on the specification for dedicated liquefied petroleum gas appliances (Parasol patio heaters) is useful for:
- Liquefied petroleum gas appliances manufacturers
- Gas-fired heater manufacturers
- Quality control manufacturers
Why should you use BS EN 14543-Parasol patio heaters?
An outdoor or parasol patio heater uses infrared (also known as radiant) heat to directly warm people within proximity of the heater. BS EN 14543 guides you with design and operating requirements.
The design requirements include suitability for various gases, materials, assembly (sturdiness), stability of the appliance, gas circuit, burner, auxiliary device, the gas cylinder housing, and protection against contact with the reflector.
The operating requirements include soundness of gas circuit, verification of the nominal heat output, operating safety, combustion, and performances. BS EN 14543 provides you with test methods to verify the compliance of design and operating requirements. BS EN 14543 guides you with the marking, packaging, and instructions of appliances. BS EN 14543 helps you to manufacture high-quality parasol patio heaters.
What’s changed since the last update?
BS EN 14543:2017 supersedes BS EN 14543:2005+A1:2007, which is withdrawn. BS EN 14543:2017 includes some technical changes with respect to BS EN 14543:2005+A1:2007. These include:
- Addition of max pressure in the scope
- Access to the cylinder valve (only one hand movement without the use of any key or tool)
- Limitation of the ignition output to 5 kW
- Requirement for internal flexible
- Distinction between wall-mounted, suspended, and grounded appliances
