Overview
EN 497:2022/prA1 is a draft amendment from CEN for dedicated liquefied petroleum gas (LPG) appliances. It covers multi purpose boiling burners for outdoor use intended for cooking vessels with a diameter greater than 300 mm. The document focuses on the constructional and performance characteristics, safety specifications, rational use of energy, test methods, and marking requirements for burners designed to heat liquids or food outdoors.
This amendment is currently in CEN Enquiry and is not yet a European Standard. It is intended to modify EN 497:2022 and supports clearer requirements for outdoor LPG boiling burners, especially where safe operation, wind resistance, and user instructions are important.
Key Topics
The draft amendment updates several important areas of the standard for outdoor gas burners and related LPG appliance safety.
Scope clarification
- Adds that the document does not cover commercial uses
- Clarifies that appliances may be with or without enclosure
Updated normative references
- Replaces older references with current standards for:
- flame supervision devices
- multifunctional controls
- rubber sealing materials
- manually operated gas taps
- Replaces older references with current standards for:
Definitions and terminology
- Revises the definition of appliances incorporating a gas cylinder
- Introduces a new definition for enclosure
Safety and performance
- Updates requirements for flame supervision devices
- Revises draught resistance testing, including wind-related conditions
- Adds an example apparatus for the draught test
Instructions for use
- Strengthens guidance for installation, assembly, use, and maintenance
- Highlights ventilation, appliance surroundings, and restrictions on accessories such as wind shields
Informative technical rationale
- Adds Annex E explaining technical choices related to flame supervision devices and outdoor use
Applications
EN 497:2022/prA1 is relevant for organizations involved in the design, assessment, testing, and marking of LPG outdoor cooking appliances. It is especially useful for:
- Manufacturers of multi purpose boiling burners
- Product compliance teams working on LPG appliance safety
- Test laboratories performing draught resistance and performance evaluations
- Technical writers preparing installation and user instructions
- Regulators and conformity assessment bodies reviewing outdoor gas appliance requirements
The standard is aimed at products used outdoors, generally floor standing, and fitted with one or several open burners. It is important for ensuring safety in real outdoor conditions, including exposure to wind and varied weather.
Related Standards
This draft amendment is linked to several important standards in the gas appliance area:
- EN 125 - Flame supervision devices for gas burning appliances
- EN 126 - Safety and control devices for burners and gaseous-fuel appliances
- EN 549 - Rubber materials for seals and diaphragms for gas appliances
- EN 1106 - Manually operated taps for gas burning appliances
- EN 30 series - Appliances for indoor use
- EN 203 series - Commercial and professional gas cooking appliances
