Original document

WHY A TRADE ASSOCIATION IS ALLOWED THE SAFETY DOMAIN HERE, which is not a decision to make casually. The sheet states its own standing: 'the contents have the same status as a Code of Practice so members of Liquid Gas UK are expected to conform to the information provided', written 'in collaboration with UK policy makers', and 'regulatory inspectors may choose to use the guidance to establish good practice and compliance.' That is a document the industry is held to rather than one it wrote to sell something, and 'commercialInterest: "none"' follows from the sheet containing no product, brand or purchase recommendation of any kind — it tells readers not to buy second-hand regulators. It supplies the figures no manufacturer manual can: UK butane regulators pre-set at 28-30 mbar and propane at 37 mbar, a recommended ten-year service life where the manufacturer states none, replacement on any sign of 'wear, leakage or damage', and a flat prohibition on tampering, adjusting non-user-adjustable regulators, forcing a fitting, or buying second-hand.

Safety, Technical, Equipment specification

• Explicitly not culinary practice: A gas trade association has nothing to say about how food is cooked.
• Explicitly not commercial: A trade association represents its members' industry. It is not a neutral source on that industry's market.

• “The regulator service life is specified by the manufacturer, if this is not known then the recommended service life is 10 years so long as it has been used correctly according to the manufacturer’s instructions. Regulators marked BS 3016 are now over 10 years old and it is recommended that they are replaced. ... Replace a regulator if it shows signs of wear, leakage or damage.”

  Liquid Gas UK states that a regulator's service life is specified by its manufacturer, and where that is not known the recommended service life is ten years provided it has been used correctly. Regulators marked BS 3016 are now over ten years old and are recommended for replacement, and any regulator showing signs of wear, leakage or damage is to be replaced.

  The manufacturer's figure wins and the ten years is the fallback. This is a default for the common case where a consumer has no paperwork for a regulator that came with a barbecue years ago.

  Two independent triggers for replacement — age and condition — and the condition trigger has no interval attached to it. A two-year-old regulator showing damage is replaced.

  Where it applies:

  UK. The sheet's pressures and standards are UK settings and the guidance is issued to UK members.

• “For your safety: • Do not force a regulator onto the cylinder valve if it does not fit easily; • Do not operate its mechanism using excessive force; ... • Never tamper with regulators; • Never try to adjust non-user adjustable regulators, they are pre-set by the manufacturer to control the gas supply at the correct pressure, unless you are qualified to do so; • Do not purchase or use a second-hand regulator. ... Always use the correct sized spanner to tighten any screwed connection, do not over tighten;”

  Liquid Gas UK sets out what a consumer must not do with a regulator: do not force it onto a cylinder valve if it does not fit easily, do not operate its mechanism with excessive force, never tamper with regulators, never adjust a non-user-adjustable regulator unless qualified to do so, and do not purchase or use a second-hand regulator. Screwed connections are tightened with the correct sized spanner and not over-tightened.

  The sheet's context for why adjustment is forbidden: UK butane regulators are pre-set at nominally 28-30 mbar and propane at 37 mbar, and the pre-set is what keeps appliance pressure correct.

  Most screwed cylinder connections use a LEFT-HAND thread and tighten in the opposite direction to a normal screw, which is the likeliest reason a consumer applies force to a fitting that is not going on.

  Every item here is a prohibition, which is exactly what BBQHQ may publish. None of it is a repair instruction; it is the set of things a consumer should stop doing, and stopping needs no competence to perform safely.

• In the UK, an LPG regulator is replaced on its manufacturer's stated service life, or after ten years where none is stated, and immediately on any sign of wear, leakage or damage regardless of age. Regulators marked BS 3016 are past that life by definition.
• An LPG regulator is not forced onto a cylinder valve, not operated with excessive force, not tampered with, not adjusted where it is not user-adjustable, and not bought or used second-hand. Screwed connections are tightened with the correct spanner and not over-tightened; most use a left-hand thread.

If this source changes, these are the claims that need rechecking. That is the point of recording provenance per claim rather than per page.
