Sections 5 & 6 (& 7) – Pressure Regulators, Changeover Devices and LPG Appliances

…Code of Practice 24 – Part 3 ( UKLPG CoP 24 Part 3)

Section 5 – Pressure Regulators and Automatic Changeover Devices

OPSO – All regulators and changeover devices shall have over-pressure shut-off protection (OPSO) to protect the downstream pipework and appliances from pressure greater than they are designed to withstand. There are a few exceptions (read the CoP in detail and/or speak to your engineer for more information) but when you think this stuff through it makes perfect sense – build in safeguards, and use them – always.
Pressure regulators and safety devices incorporating full vent relief valves shall not be used that could discharge LPG vapour inside a commercial premises or an event premises.
One for the engineers to check… where changeover devices are used, non-return valves at the high-pressure inlet shall be incorporated to prevent a discharge of gas when changing cylinders.

Section 6 – LPG appliances

Appliances shall

  • have all burners protected by Flame Supervision Devices (FSD) which are also known as Flame Failure Devices (FFD).
  • be installed in accordance with
    • The Gas Safety (Installation and Use) Regulations 1998
    • the manufacturer’s instructions
    • any other relevant British Standard(s)

Appliances shall be used and maintained

  • in accordance with the manufacturer’s instructions

Flexible hoses shall be examined regularly for damage or wear and replaced as necessary

In this section there is also guidance for grillers and toasters, bain-maries and barbeques.

Section 7 – LPG Generators

Please read the CoP for the full details of the guidance for the setup and use of an LPG Generator

Please note: Throughout this series of articles we have used the word ‘shall’ in all circumstances rather than swapping between should and shall. The difference is important and the CoP specifies which are mandatory and which are not – your LPG certified Gas Engineer can help you to understand where there is any scope. By using ‘shall’ in all circumstances here we are reducing the impact of any misinterpretation caused by our paraphrasing of the code of practice.
