Cylinder Installation Safety Guide

1. Cylinder storage and positioning

Storing and positioning your gas cylinder is an important part of keeping your home safe and making sure everything works as it should. As cylinders contain gas under high pressure, placing them in the wrong spot, such as a cramped or poorly ventilated area, can increase the risks of leaks or pressure build-up. By following our easy storage and positioning guidelines, you can reduce risks and handle your gas cylinder safely and with confidence.

• Propane cylinder(s) shall be positioned outdoors.
• All cylinder(s) shall be stored on a flat, stable surface.
• Always store and use cylinder(s) upright, with the valve at the top.
• Ensure the storage area is well-ventilated and away from heat and ignition sources.
• Keep the valve protection cap fitted when cylinder(s) are not connected.
• Protect cylinder(s) from damage, impact, or dropping.

By following this guide, you’ll be able to store and position your gas cylinders safely while reducing the risk of leaks, damage, or accidents. Taking extra care goes a long way in keeping everything running smoothly. Always handle cylinders with care and refer to manufacturer instructions to maintain a safe and reliable gas supply. 

2. Before disconnecting cylinders

Before disconnecting your gas cylinder, make sure all valves are fully closed  Fellow appliances are turned off. There are two types of cylinders: hand wheel and self- closing – follow the right steps for your specific type.  

Self-closing cylinder valve:

• Ensure that the appliance is turned off, and regulator valve is switched OFF before disconnecting from the cylinder add clip on regulator image. 

These guidelines allow you to safely disconnect your gas cylinder. Taking the time to carry out these steps carefully will help prevent gas leaks, protect equipment, and keep you safe whilst disconnecting your gas cylinder.

3. Connecting Cylinders

Before connecting the regulator, it’s a good idea to do a quick safety check to make sure your cylinder is in good working condition. Taking a moment to check everything can help prevent issues and give you peace of mind.

There are two main types of cylinders: hand wheel and self-closing, so be sure to follow the guide that matches your cylinder type for the safest results.

Before connecting regulator check that the cylinder valve, seals, hoses, regulator and associated appliance(s) are in safe working condition

Following these guidelines and ensuring all parts are in safe working condition will help provide a safe, secure connection and reliable operation of your gas system.

5.Hoses & Regulator - Inspection and Replacement

Before connecting or replacing your gas cylinder, it’s important to carry out a few simple checks and routine maintenance to make sure everything is safe and in good working order. Taking a little time to do this can help prevent problems and keep your setup running smoothly. Follow the guidelines below to confidently inspect and replace your gas cylinder the right way.

Before connecting or replacing cylinders:

• Check the condition of:
  • Pressure regulator & assemblies.
  • Hoses and manifolds.
  • Sealing washers.

• If any component shows evidence of wear, cracking, damage, or deterioration, do not connect cylinders
• Contact your Gas Supplier or an RGI/Gas Safe registered engineer.

Ongoing maintenance:

• Inspect hoses and manifolds regularly.
• Replace hoses in line with manufacturer guidance (typically every 5 years).
• Replace regulators:
  • As specified by the manufacturer, or
  • After 10 years in service, whichever occurs first.
• IMPORTANT: ensure the regulator vent is always positioned facing downwards.
• If any component shows wear, cracking, damage, or deterioration, do not use the installation
• Contact your Gas Supplier or an RGI/Gas Safe registered engineer.
• It is recommended that installations and appliances are inspected annually by an RGI/Gas Safe registered engineer.

By following these guidelines and maintenance practices, you can ensure your safety and the safety of your property when inspecting and replacing your gas cylinder.

6. Regulator Upgrade Recommendation (propane cylinder installations)

Gas installations and equipment should meet current safety standards and include the right built-in protections. Following our guide below ensures your system remains compliant and properly protected keeping you and your property safe.

• The gas installation, regulators and assemblies should conform to latest standards, (e.g. IS 813) and industry best practice.
• Where a single-stage pressure regulator is currently installed, consult with an RGI/Gas Safe registered engineer, as it is strongly recommended to be replaced with a model incorporating both, over-pressure and excess flow protection.

Note: Upgrading provides protection against damage to the downstream installation pipework and appliances in the event of regulator malfunction

By following this, you can help ensure your gas installation remains safe, compliant, and protected. Regularly reviewing your system in line with current standards and seeking professional advice where needed will support safe and reliable operation.

8. If You Smell Gas

If you smell gas, it’s important to stay calm and act quickly to keep everyone safe. Follow our guide below for simple steps you can take to protect yourself, others, and your property.

• Turn off the gas supply at the cylinder(s)
• If Butane cylinder(s) are indoors, remove to well-ventilated outdoor area if safe to do so
• Note: Only Butane (yellow) cylinders are permitted indoors. Propane cylinders must always be stored and or connected outdoors
• Extinguish all naked flames.
• Do not vape or smoke.
• Do not turn electrical switches or appliances on or off (including lights, phones, doorbells).
• Ventilate and evacuate the area.
• Do not use a phone in the area
• Contact your gas supplier or an RGI/Gas Safe registered engineer from a safe place.
• In case of immediate danger, contact emergency services on 999 / 112.

Taking prompt and correct action when you smell gas can help prevent serious harm and ensure the situation is safely resolved.

9. Important note

All inspection, maintenance, and repair work must be carried out by an RGI/Gas Safe registered engineer.

10. RGI and Gas Safe - Jurisdictional Clarification

When we mention a Registered Gas Installer (RGI) or a Gas Safe registered engineer in this guide, we’re simply referring to a qualified gas professional. These terms are used broadly and apply across different regions, so you can feel confident you’re working with someone properly trained and competent.

Northern Ireland (NI):
These are referred to as Gas Safe registered engineers.
