What is a High-Level Gas Connection? #
A high-level gas connection is a method of connecting certain freestanding gas cooking appliances using a certified flexible gas hose that connects to the rear of the appliance rather than near the floor.
When installed correctly, this connection method helps prevent strain on the hose, reduces the risk of damage, and allows the appliance to be safely moved for servicing when required.
High-level connections must comply with the relevant Australian Standards and can only be used where the appliance has been designed and approved for this type of installation.
When Can a High-Level Connection Be Used? #
A high-level connection may only be installed when:
- The cooking appliance is approved for a high-level connection.
- A certified flexible gas hose is used.
- The installation complies with the current Australian Standards.
- The gas connection location meets the required installation dimensions.
- A suitable restraint system has been fitted.
Not every freestanding cooker is suitable for this connection method.
Key Installation Requirements #
A compliant installation generally includes:
- A certified flexible gas hose.
- A hose length appropriate for the appliance.
- A downward-facing gas connection.
- Correct alignment between the wall connection and the appliance connection.
- An approved restraining chain or cable to prevent excessive movement.
- Adequate clearance to prevent the hose from being crushed, stretched or kinked.
These requirements help ensure the appliance can be moved for cleaning or servicing without placing stress on the gas connection.
Why is the Restraining Chain Important? #
The restraining chain prevents the appliance from being pulled too far away from the wall.
Without a properly installed restraint, the flexible hose may:
- Stretch excessively
- Become damaged
- Disconnect
- Develop gas leaks
- Create a serious safety hazard
A correctly fitted restraint is an essential safety component of the installation.
Common Issues Identified During Gas Safety Inspections #
Our licensed gas fitters commonly find:
- Missing restraining chains
- Incorrect hose routing
- Damaged flexible hoses
- Hoses under tension
- Kinked or twisted hoses
- Incorrect gas connection positions
- Appliances not installed in accordance with manufacturer instructions
- Unapproved connection methods
Where defects are identified, recommendations will be provided to restore the installation to a safe condition.

Frequently Asked Questions #
Can every freestanding cooker use a flexible hose? #
No. Only appliances that have been designed and certified for this connection method should be connected using a flexible hose.
Can I remove the restraining chain? #
No. The restraining chain is an important safety feature and should remain securely attached.
Why is the hose positioned high behind the cooker? #
High-level connections help protect the hose from damage while allowing sufficient movement for servicing and cleaning when installed correctly.
