Changing the Gas Bottle

You will find the gas bottles in the dedicated gas locker — usually a separate, vented compartment on the outside of the camper. Have the full bottle ready before you disconnect the empty one.

1. Turn everything off. Switch off the hob, oven, water heater and gas heating inside the camper.
2. Close the top valve on the bottle. Turn the handwheel on top of the bottle clockwise until it is fully closed. This is the most important step — always do it first.
3. Burn off the residual gas (recommended). Light a hob ring for a few seconds until the flame dies out. This releases the pressure left in the hose. Then switch the hob off again.
4. Release the click coupling. Grip the outer collar (the sliding ring on the coupling) and slide it firmly upwards. The coupling releases and lifts straight off the bottle valve.
5. Remove the bottle. Undo the strap/clamp and lift the empty bottle out. Fit its protective cap.

1. Place the full bottle in the locker and secure it with the strap/clamp so it stands firmly.
2. Check the top valve is closed (turned fully clockwise) before you connect.
3. Check the seal. Make sure the rubber O-ring/seal inside the coupling is present and undamaged — no gas passes a cracked or missing seal.
4. Place the click coupling straight down onto the bottle valve — level and square, not at an angle.
5. Push the collar ALL the way down until it clicks and locks. This is where most people fail:

   Use firm, steady downward pressure. It gets a little stiff right at the end — keep pushing until you hear/feel a clear click and the collar sits in its lowest position. If the collar is only half-way up, the valve pin is not pressed in and you will get no gas.

6. Check it is locked. Gently try to lift the coupling straight up without touching the collar. If it stays firmly attached, it is locked correctly.

1. Open the top valve slowly (anti-clockwise), all the way open.
2. Leak test. Brush a little soapy water onto the coupling. Bubbles = a leak → close the valve immediately and reconnect. No bubbles = sealed and safe.
3. Light a hob ring. The first time after a change it can take several seconds before the gas reaches the burner — there is air in the hose. Let it run until it lights steadily.

After a gas change there is air in the line, so appliances may need a few attempts and some patience before they run.

Fridge (on gas):

1. Set the fridge selector to gas mode (the flame symbol). On many fridges this is automatic (AES/MES) — it will try to ignite on its own.
2. If it is manual: hold the gas/ignition knob in and press the igniter (or turn to the spark symbol) repeatedly until the flame catches. Keep the knob held in for ~15 seconds after it lights, then release.
3. A small indicator (window or LED) confirms the flame is burning. If it clicks but does not light, wait a moment for the air to clear and try again.

Heating / water heater (Truma or similar):

1. Turn the heater control on and select the temperature or "hot water" setting.
2. It will attempt automatic ignition (you may hear ticking). After a gas change, allow it to retry a couple of times while the air clears.
3. Hot water on gas takes time — calculate up to one hour for the water to get hot after a gas change.

1. Collar not fully down (most common) → slide it all the way down until it clicks.
2. Top valve not fully open → open it all the way.
3. Air in the hose → let the burner run a few seconds; the gas will come.
4. Empty or unfilled bottle, or a missing/damaged seal in the coupling.
