Gas Cylinder and Appliance Gas Connection Changes

Did you know that the connections on our gas pizza ovens are changing? We’re here to explain why, how this affects you and your gas ovens, and what you need to do to ensure that your oven and gas cylinder continue to work together to produce perfect pizza!

Why are the gas connections changing?

Basically, legislation and Australian Standards have changed to make way for a new valve and connector to all LPG cylinders under 25L. The old type (Type 21 POL) must be replaced by the new type (LCC27) on all appliances manufactured after 1 April 2022.

It’s a safety thing! The new connector on the regulator end of the oven hose now includes a thermal fuse that stops the flow of gas if the connection is subjected to fire. It also has a back check valve that must be engaged by having a positive connection to the oven hose before gas can flow.

These are additional safety precautions, but they do not render the old POL unsafe. Australian Standards still support the use of the old POL connections if used correctly.

My gas pizza oven was delivered with the old Type 21 POL connection. What do I need to do?

Some of the gas pizza ovens in our warehouse were manufactured prior to the 1 April 2022 switch-over date. And some have been manufactured more recently.

As a result, we currently have gas ovens with old POL connections and some with the new LCC27 connections.

Unfortunately we can’t confirm which connection you will receive.

If you receive an oven with the Type 21 POL connection on the regulator end of the hose, it will still safely screw into the new LCC27 valve on the new cylinders. As will all your other gas appliances that you own (your BBQ, for example).

You do NOT require an adaptor (in fact adapters are very specifically precluded from use in Australian Standards as they increase the risk of a gas leak. Please do not attempt to use any form of adapters). The LCC27 cylinder works best with the LCC27 oven connection, but it can also safely and effectively be used with the old POL oven connection.

All gas cylinder connections from 1 April 2022 will have the new LCC27 connector.

If you receive an oven with the new LCC27 connection, it will not be compatible with the old POL cylinders. The new oven connection will only connect to a cylinder with the new LCC27 valve. In this case, you need to return your partially filled cylinders to a swap and go facility for exchange with a cylinder with the new LCC27 valve.

As noted above, adaptors must not be used as there is an increased risk of gas leakage.

How can I tell which gas oven connection I have?

The new LCC27 connection has a broader handwheel and the brass connection has a shield. This connects to the new LCC27 cylinder connection that has a visible external thread on the valve.

The old POL connection has a smaller handwheel and the brass connection is exposed, without a shield. This connects to both the new LCC27 cylinder connection and the old POL cylinder connection.

I am still confused!
