Why Are Outdoor Installation Requirements Important? #

Some gas appliances are specifically designed to operate outdoors, while others are intended for indoor use only.

Installing an appliance in the wrong location can affect its performance, reduce ventilation, increase the risk of carbon monoxide exposure and create significant safety hazards.

For this reason, gas appliances must always be installed in the location specified by the manufacturer and in accordance with the relevant Australian Standards.

What Is Considered an Outdoor Area? #

An outdoor area is generally an open space that provides sufficient natural ventilation for the safe operation of a gas appliance.

Examples include:

• Open patios
• Verandahs
• Courtyards
• Open balconies
• Outdoor entertaining areas

The amount of permanent open space is important. Adding walls, blinds, shutters or other enclosures may reduce ventilation and change whether an area is considered suitable for an outdoor appliance.

Outdoor Appliances Must Be Designed for Outdoor Use #

Only appliances specifically approved and labelled for outdoor installation should be installed outdoors.

Common outdoor gas appliances include:

• Continuous flow gas hot water systems
• Outdoor gas storage water heaters
• Outdoor gas barbecues
• Outdoor radiant heaters
• Certain pool and spa heaters

Indoor appliances must not be installed outdoors unless the manufacturer specifically permits that installation. Likewise, appliances designed only for outdoor use must not be installed indoors.

---

Ventilation Requirements #

Outdoor gas appliances rely on adequate airflow for safe combustion.

The installation should ensure:

• Fresh air can circulate freely around the appliance.
• Flue gases can disperse safely.
• Air inlets and vents remain unobstructed.
• Future building work does not restrict ventilation.

Installing blinds, walls or glazing around an existing outdoor appliance may create an unsafe environment if ventilation is reduced.

---

Weather Protection #

Outdoor appliances are designed to withstand normal weather conditions, but they should still be installed in accordance with the manufacturer’s instructions.

Depending on the appliance, this may include protection from:

• Heavy rain
• Flooding
• Excessive wind
• Physical damage
• Corrosion

The appliance should never be enclosed in a way that prevents safe operation or ventilation.

---

Safe Access for Servicing #

Outdoor gas appliances should be installed where they can be safely accessed for:

• Routine servicing
• Maintenance
• Repairs
• Inspection
• Replacement

If an appliance is mounted high on a wall or roof, additional access equipment or fall protection may be required to allow safe servicing.

Common Issues Found During Gas Safety Inspections #

Our licensed gas fitters regularly identify:

• Outdoor appliances enclosed by new building works.
• Retractable blinds that restrict ventilation.
• Blocked air intake or flue areas.
• Appliance locations that do not allow safe servicing.
• Corrosion caused by prolonged weather exposure.
• Incorrect appliance type for the installation location.
• Damage from impact or poor mounting.

Where safety concerns are identified, recommendations will be included in the inspection report.

What We Check During a Gas Safety Inspection #

During a gas safety inspection, our licensed gas fitters may assess:

• Appliance location.
• General condition.
• Ventilation around the appliance.
• Signs of corrosion or weather damage.
• Accessibility for servicing.
• Flue termination (where applicable).
• General installation safety.

If any issues affecting safety or compliance are identified, they will be documented in the inspection report.

Property Improvements Can Affect Compliance #

Outdoor gas appliances may have been compliant when originally installed, but later renovations can change the installation.

Examples include:

• Installing café blinds.
• Building new walls.
• Enclosing an alfresco area.
• Adding roofing or glazing.
• Constructing outdoor rooms around the appliance.

These changes may reduce ventilation and affect the safe operation of the appliance. Before enclosing an outdoor area, seek advice from a licensed gas fitter.

Frequently Asked Questions #

Can an outdoor gas appliance be enclosed later? #

Not always. Enclosing an appliance that was designed for outdoor use may create a dangerous situation by restricting ventilation and trapping combustion gases.

---

Can an indoor gas appliance be installed outside? #

Only if the manufacturer specifically approves that installation. Otherwise, indoor appliances should only be installed indoors.

---

Are café blinds considered walls? #

They can be. Depending on how they are installed, blinds may reduce ventilation and affect whether the area is still considered an outdoor location for gas safety purposes.

---

Who should assess an outdoor gas appliance installation? #

A licensed gas fitter can assess whether the appliance location, ventilation and installation meet the applicable requirements and manufacturer instructions.
