Setting up your caravan's gas system upon arrival at a campsite is essential for ensuring the safe and efficient operation of your heating, cooking, and hot water appliances. This guide to caravanning will help you understand the components and their connections, particularly the left-handed threads commonly used in gas fittings, which are crucial for a secure setup.
What You’ll Need Before You Start:
Gas Bottle(s): Ensure they are suitable for your caravan’s system (e.g., propane or butane).
Gas Hose: Connects your gas bottle to the caravan's system.
Regulator: Controls the pressure of the gas.
Gas Spanner: For tightening connections.
Leak Detector Spray: To check for gas leaks.
Gloves and Safety Goggles: Optional but recommended for added protection.
Step-by-Step Guide to Setting Up Your Caravan Gas System
Position Your Caravan Safely
Park your caravan on level ground to ensure safety and proper functioning of the gas appliances.
Check the Gas Bottle
Inspect your gas bottle(s) to ensure they are securely restrained and free of damage. Check that the connection thread is free of contaminants and that the type of gas (propane or butane) matches your caravan’s system requirements.
Attach the Regulator to the Gas Bottle
Connect the gas regulator to the gas bottle valve using the pig tail hoses. Gas bottle threads are left handed threads (see below for further details) and should be secure but not over-tightened. Use a gas spanner or an adjustable spanner to tighten the connection properly.
Turn On the Gas Supply
Before turning on the gas, double-check that all connections are tight and secure. Turn the gas supply on at the bottle’s valve slowly to avoid sudden pressure changes.
Check for Gas Leaks
It's vital to check for any leaks before using the gas system. Use a leak detector spray to check all connections, including the regulator, hose, and gas inlet. If bubbles form, this indicates a leak, and you’ll need to tighten the connections or replace faulty components. Alternatively, a mixture of water and washing-up liquid can be applied to the connections; bubbles will form if there's a leak.
Test the Appliances
After confirming there are no gas leaks, test each gas appliance individually, starting with the least important. This helps identify any issues with specific appliances. If all appliances function correctly, your gas system is set up properly.
Keep an Eye on the Gas Levels
Monitor your gas levels during your stay. Some gas bottles have built-in gauges, but if yours doesn’t, keep a spare bottle on hand to avoid running out unexpectedly. Always check gas levels before leaving home.
Turn Off the Gas When Not in Use
For safety reasons, always turn off the gas supply at the bottle when not using the caravan. This prevents accidental leaks or gas build-up in the system. It's also advisable to turn off the gas when leaving the caravan unattended for extended periods.
Understanding Left-Handed Threads in Caravan Gas Systems
Many gas fittings, particularly those connecting the gas bottle to the regulator, utilise left-handed (reverse) threads. This means that to tighten the connection, you turn the nut counter clockwise (anti-clockwise), and to loosen it, you turn it clockwise. This design prevents accidental disconnections during operation. It's essential to recognise these fittings, as they are standardised and marked with a notch on the hex nut for easy identification.
Safety Instructions:
Naked Flames and Sparks Warning: Never use naked flames or allow sparks near the gas system, whether during setup or while the system is in operation. Sparks, static electricity, and open flames can ignite gas vapours, leading to the risk of fire or explosion. Always ensure your caravan’s gas appliances are used in a well-ventilated area, and never smoke or expose the gas system to any potential sources of ignition, such as lighters, matches, or electrical sparks.
Ventilation is Key: Always ensure your caravan is well-ventilated when using gas. Never block vents or airways, and open windows when cooking or heating.
Regularly Check for Leaks: Even when not in use, regularly check your gas connections for leaks.
Storage of Gas Bottles: Always store gas bottles outside the caravan, preferably in dedicated gas locker or secure shaded, and well-ventilated area. Never store gas bottles indoors or in confined spaces.
Never Use Damaged Gas Hoses: If your gas hose shows signs of wear or damage, replace it immediately. A damaged hose can lead to dangerous leaks.
Seek Professional Help if Needed: If you're unsure or uncomfortable handling the gas system, contact a professional to inspect or set up the system for you. Your safety is the top priority.
Conclusion
Setting up your caravan’s gas system upon arrival at a campsite is essential for ensuring the safe and efficient operation of your heating, cooking, and hot water
