A gas BBQ on the back deck is one of the most common gas appliances in Brisbane homes. Many families use theirs most weekends from spring into autumn, and outdoor heaters come out on cooler evenings too. Because these appliances sit outside, they are easy to forget about, and most people never think about how the gas reaches them or how the connection was made.
Outdoor gas safety depends on details you cannot see from the grill. The hose behind the BBQ, the way the appliance is positioned, how much air moves around it, and how enclosed a covered patio really is all affect how safe it is. Brisbane’s warm, humid summers keep people outdoors under roofs, screens and pergolas, and that is exactly where ventilation problems tend to creep in.
Any gas installation, repair or alteration is work for a licensed gas fitter, and nothing here replaces one.
Key Insight:
A safe outdoor gas appliance depends on a licensed installation, open airflow and a hose that is checked regularly.
Why the installation matters more than the appliance
A well-made BBQ or heater still needs to be installed properly to be safe. A licensed gas fitter checks the gas supply, the isolation valve, the connection and the clearances around the appliance against the manufacturer’s instructions. They also look at whether the spot you have chosen suits the appliance, which is often the step homeowners skip.
If a BBQ has been moved, or a new patio cover has gone up since it was installed, the original setup may no longer be right. Our gas fitter services for West End homes include this kind of review.
How outdoor gas BBQs and heaters should be installed and ventilated
Gas appliances need fresh air to burn cleanly, and the fumes they produce need somewhere to go. Outdoors, that happens naturally when the space is open. Problems start when a covered area has walls or screens on most sides and the air has nowhere to move.
These rules of thumb help when you look at your own space:
- Keep the appliance well clear of doors, windows and air intakes, and follow the clearances in the manufacturer’s manual.
- Use it in an area with open sides, never inside a tent, shed, garage or enclosed sunroom.
- Ask a licensed gas fitter to check any new patio cover, enclosure or screen before you use an appliance underneath it.
- Never run a gas BBQ or heater indoors, even for a short time or on a cold night.
Flexible hoses and connections need regular attention
Many outdoor gas BBQs connect to the supply through a flexible hose, and that hose is the part most likely to wear. Rubber and reinforced hoses can crack, perish, kink or flatten over time, especially when they sit in the sun or get pinched behind a moved appliance. Dragging a BBQ across the deck can stress both the hose and its fittings, so lift it rather than sliding it.
When you look at the hose, check for:
- cracks, splits or bulges in the outer covering
- kinks, flattening or sharp bends
- contact with hot surfaces or moving parts
- signs of age, such as hardening or discolouration
If you see any of these, turn the appliance off and call a licensed gas fitter. Do not try to repair or replace the hose yourself. As a rule of thumb, have a fitter check flexible connections at every service and replace them on their advice, rather than waiting until the damage is obvious.
The soapy water test is a fitter’s check, not a home fix
A licensed gas fitter uses a soapy water test to look for leaks at connections. With the gas on, a soapy solution is brushed over the joints, and bubbles forming at a joint show that gas is escaping. It is a simple visual check, and it is one of the standard ways fitters confirm that a connection is sound.
As a homeowner, you can look over the hose and fittings, but go no further. Do not tighten, loosen, wrap or swap anything, and do not use a flame to hunt for a leak. If you hear hissing or notice a gas smell, follow the steps below and call a licensed gas fitter.
Carbon monoxide: the risk in enclosed spaces
Gas appliances burn fuel to make heat, and when they do not get enough air, they produce carbon monoxide. This gas is colourless and odourless, so your senses will not warn you about it. It builds up fastest in small or closed spaces such as tents, caravans, boats, garages and enclosed patios. An appliance that seems fine in the open can become dangerous once it is moved under a closed roof.
Symptoms can include headache, dizziness, nausea and confusion. They are easy to mistake for tiredness or a heavy meal, and that is what makes carbon monoxide so risky. If someone feels unwell while an appliance is running, move everyone into fresh air straight away and call 000.
What to do if you smell gas
Treat any gas smell as an emergency. Follow these steps:
- Leave the building straight away and take everyone with you.
- Do not use light switches, power points, phones, lighters or anything else that could make a spark or flame, inside or near the area.
- Do not try to find or fix the source of the smell yourself.
- Once you are clear and upwind, call the emergency line for your gas network, or call 000 if you cannot reach it or someone is hurt.
- Stay away until you are told the area is safe, then arrange gas leak repairs with a licensed gas fitter.
Gas leak repairs should always be carried out by a licensed gas fitter, who can find the fault and fix it safely.
Book a licensed inspection before the summer entertaining season
Late spring is a good time to get an outdoor gas appliance checked. Hoses and fittings may have sat in the sun or under a cover through winter, and a BBQ used only now and then may need a closer look. Booking early means any issues are dealt with before the busiest weeks. Our safe gas fitting services across Brisbane explain what the work involves.
A licensed inspection covers the appliance’s position, the ventilation around it, the hose and its fittings, and the connections. If you have added a patio cover, screens or a new heater since installation, tell the fitter, because those changes affect airflow.
Key Takeaways
- Outdoor gas appliances should be installed, moved and repaired only by a licensed gas fitter.
- Airflow matters more than most people expect, so never run a BBQ or heater in an enclosed space.
- Check the flexible hose for cracks, kinks and age, and leave any repairs to a fitter.
- Carbon monoxide is odourless, so treat headaches and dizziness near a running appliance as a warning sign.
- If you smell gas, leave, avoid switches and flames, and call the gas emergency line or 000.
Frequently Asked Questions
Can I install an outdoor gas BBQ myself?
No. Connecting, moving or replacing a gas BBQ, hose or fitting must be done by a licensed gas fitter. Even when the steps look simple, a fitter checks the connection, the clearances and the airflow together, and that combination is what keeps the setup safe.
Is it safe to run a gas heater under a covered patio?
It depends on how enclosed the space is and how much air can move through it. A patio with open sides is very different from one with walls or screens on most sides. A licensed gas fitter can assess the space, tell you whether the heater suits it, and advise where it should sit.
How often should outdoor gas appliances be checked?
As a rule of thumb, have them inspected by a licensed gas fitter before the heavy-use season, and again whenever something changes, such as a new cover or a moved appliance. Follow the service advice in the appliance manual too.
Whether your home is in Carina, Balmoral or elsewhere across Brisbane, the same principles apply to every outdoor gas setup. If you are not sure how your BBQ or heater was installed, or you have noticed a hose that looks worn, the team at SJK Collective can talk it through with you. You can reach out through the enquiry form on our website, and we will tell you what to expect next. Planning that check now means your outdoor space is ready well before the first big gathering. A licensed gas fitter should always do the work, from the first look to the final test.
