Tips for Maintaining Your Gas Appliances

Why Gas Appliance Maintenance Matters

Gas appliances are reliable and efficient, but like any equipment they need regular attention to operate safely. Poorly maintained gas appliances can develop faults that lead to gas leaks, carbon monoxide poisoning, or house fires. The good news is that most maintenance tasks are simple and can be done by homeowners, while more technical servicing should be handled by a licensed gas fitter.

Gas Cooktops and Ovens

Your gas cooktop works hard every day and is one of the easiest appliances to maintain:

• Clean burner caps and rings regularly — food debris and grease can block the gas ports, causing uneven flames or difficulty lighting. Remove the caps and soak them in warm soapy water monthly
• Check flame colour — a healthy gas flame is blue with a small yellow tip. If your flames are mostly yellow or orange, the burner isn't getting enough air and needs cleaning or adjustment
• Inspect gas hose connections — if your cooktop uses a flexible gas hose, check it for cracks or brittleness every six months. Replace bayonet hoses every 5 years as per manufacturer recommendations
• Keep the area around the cooktop clear — flammable materials such as tea towels, paper towels, and curtains should be kept well away from open flames

Gas Heaters

Gas heaters should be serviced by a licensed gas fitter every two years, but there are things you can do between services:

• Clean or replace filters — ducted gas heaters and some space heaters have filters that trap dust. Clean them at the start of each winter season
• Check flue and ventilation — ensure the flue pipe (if applicable) is clear of obstructions such as bird nests or leaves. Never block ventilation openings in rooms with gas heaters
• Look for soot or discolouration — black marks or soot around a gas heater indicate incomplete combustion, which may produce carbon monoxide. Stop using the heater and call a gas fitter immediately
• Test carbon monoxide alarms — if you have gas heaters, install CO alarms on every level of your home and test them monthly

Gas Hot Water Systems

Gas hot water systems are generally low-maintenance but benefit from periodic attention:

• Check the pilot light — if your storage system has a pilot light, ensure it burns a steady blue flame. A flickering or yellow pilot light needs professional attention
• Test the pressure relief valve — lift the lever on the TPR (temperature and pressure relief) valve once a year to ensure it operates freely. Water should flow from the valve and stop when you release the lever
• Flush the tank annually — sediment builds up in gas storage tanks just like electric ones. Open the drain valve at the bottom and flush until the water runs clear
• Check the anode rod — the sacrificial anode protects the tank from corrosion. Have it inspected every 3-5 years and replace when it's worn down

When to Call a Professional

Always call a licensed gas fitter if you smell gas, notice yellow or sooty flames, hear unusual noises from gas appliances, or if an appliance keeps shutting off unexpectedly. Never attempt to repair gas connections or internal components yourself — gas work must be performed by a licensed professional under Australian law.
