EN 497:2022/prA1 is a CEN draft amendment to EN 497:2022 for dedicated liquefied petroleum gas (LPG) appliances used outdoors to heat cooking vessels with a diameter greater than 300 mm. It updates the European Standard's scope, terms, test method, instructions, normative references, and Annex ZA, and it adds an informative Annex E on flame supervision device (FSD) choices. The amendment is aimed at manufacturers, test laboratories, certification bodies, and others who design, check, or document these outdoor LPG appliances.
What does EN 497:2022/prA1 specify?
EN 497:2022/prA1 specifies amendments to the existing European Standard for multi purpose boiling burners for outdoor use. The base standard applies to floor-standing appliances with one or more open burners, with or without enclosure, for heating vessels that contain liquids or food and are operated with the gas categories named in Clause 4.
The amendment also narrows the scope by excluding commercial uses. That matters in practice because this document is for outdoor non-commercial appliances, not for professional catering or indoor products.
| Annex | What it covers |
|---|---|
| Annex E | Explanation of the technical choices retained for the standard relating to a flame supervision device (FSD) |
| Annex ZA | Relationship between EN 497 and the essential requirements of Regulation (EU) 2016/426 aimed to be covered |
The amendment is organized as edits to Clause 1, Clause 2, Clause 3, 5.14, 5.17, 7.3.4.3, and 8.3, plus the new Annex E and a revised Annex ZA. That structure tells a reader where the scope, definitions, test method, user instructions, and EU-law link are updated.
What are the key requirements of EN 497:2022/prA1?
Scope and product definition
EN 497:2022/prA1 updates Clause 1 so the standard covers outdoor appliances with or without enclosure and excludes commercial uses. In practice, a product team needs to confirm that the appliance is an outdoor LPG appliance for non-commercial use before applying this standard.
Clause 3 also updates the definition of an appliance incorporating a gas cylinder and adds a definition of enclosure. That matters because cylinder storage/support and burner-surrounding enclosures are treated explicitly in the safety text and instructions.
Referenced components and controls
Clause 2 replaces several normative references with newer editions for flame supervision devices, multifunctional controls, rubber seals and diaphragms, and manually operated taps. In practice, the appliance design and verification work has to follow the current versions of those component standards, not earlier editions.
Flame supervision devices and enclosure wording
Clause 5.14 adds a note pointing to informative Annex E for FSD information, and Clause 5.17 replaces “compartment” with “enclosure”. In practice, the standard treats the burner-surrounding space consistently and gives the reader a separate explanation of why FSD is handled the way it is for outdoor use.
Draught resistance test
Clause 7.3.4.3 rewrites the draught resistance test. The appliance is tested at normal test pressure, each burner is covered with a test vessel, the test is run at full rate and repeated at reduced or half rate depending on the tap type, and the burner is exposed to a 4 m/s laminar draught with repeated gusts and changes in orientation.
This matters because flame stability is a central outdoor safety issue. The revised test also covers door movement where a casing door exists, so a manufacturer has to check performance under wind and opening/closing effects, not only under steady conditions.
Installation, assembly, use and maintenance instructions
Clause 8.3 adds warnings about not blocking ventilation openings, avoiding installation conditions that allow unburnt gas to accumulate below the burner, considering local installation rules, and preventing use of accessories not allowed by the instructions, such as a wind shield or additional legs. In practice, the instruction manual becomes part of the safety solution and must guide the user away from unsafe placement and accessories.
What terms does EN 497:2022/prA1 define?
- Appliance incorporating a gas cylinder - An appliance whose body or support includes a compartment for an LPG cylinder, or a fixing or support device for that cylinder.
- Enclosure - A part of the appliance that partly or completely surrounds one or more burners and creates a confined space where combustion occurs.
- Flame supervision device (FSD) - A safety device discussed in Clause 5.14 and Annex E in relation to flame control and outdoor wind conditions.
- Draught resistance - The ability of the appliance to keep safe flame behavior when exposed to wind and door movement during the test in Clause 7.3.4.3.
- Reduced rate position - The lower burner setting used in the draught test when the appliance has taps with marked positions.
- Variable positions - Tap positions where the burner output can be adjusted continuously, with the draught test repeated at half rate.
Who uses EN 497:2022/prA1?
EN 497:2022/prA1 is used by manufacturers of outdoor LPG boiling burners, especially floor-standing products for vessels over 300 mm in diameter. It is also used by test laboratories, certification and conformity assessment bodies, and technical writers who prepare installation, use, and maintenance instructions.
Quality managers, buyers, and compliance teams use it to check whether a product belongs in this product family, whether its components match the referenced standards, and whether its user information covers outdoor placement, ventilation, and accessory limits.
What changed in EN 497:2022/prA1 from the previous edition?
EN 497:2022/prA1 amends EN 497:2022 by making these stated changes:
- excluding commercial uses from the scope;
- updating the normative references;
- increasing the wind speed used in the draught resistance test;
- improving instructions on ventilation conditions and the use of accessories;
- adding a new Figure 4 for the draught-test apparatus;
- adding informative Annex E on the technical choices related to FSD;
- updating Annex ZA for the link with Regulation (EU) 2016/426.
Which standards are used with EN 497:2022/prA1?
- EN 125:2022+A1:2024 - flame supervision devices for gas burning appliances; it provides the referenced thermoelectric FSD standard.
- EN 126:2025 - safety and control devices for burners and appliances burning gaseous fuels; it provides the multifunctional control standard.
- EN 549+A1:2023+A2:2024 - rubber materials for seals and diaphragms for gas appliances and gas equipment; it supports sealing materials.
- EN 1106:2022+A1:2023 - manually operated taps for gas burning appliances; it supports the tap types used in the appliance.
- EN 30 series - cited in Annex E for products used indoors.
- EN 203 series - cited in Annex E for commercial/professional use products.
What does the EN 497:2022/prA1 document contain?
EN 497:2022/prA1 contains clause-by-clause amendment text for scope, references, definitions, flame supervision devices, enclosures, draught resistance, and instructions. It also contains a new informative Annex E that explains why the standard handles FSD and outdoor wind exposure in the way it does.
The amendment adds a new draught-test apparatus figure and renumbers the later figure accordingly. It also revises Annex ZA so the European Standard’s relationship to Regulation (EU) 2016/426 is kept aligned with the updated text.
