Demonstration Videos

We have two video clips which show plainly the difference between Gasfuse and flow restricting regulators.

Flow Restrictors Leave The Fire Burning!

The video shows a barbecue that is not protected by a Gasfuse. With only a flow restricting regulator, a10 inch flame continues to burn.

A worse case than this is if the gas coming out of the hose did not ignite immediately. LPG is heavier than air, and forms explosive pools at ground level. Gas will build up and ignite suddenly.

Gasfuse Stops The Gas Completely

The video shows a backyard barbecue in operation. The hose is deliberately cut, to simulate a sudden rupture such as the hose coming apart, or burning through due to a grease fire. Only Gasfuse stops the gas completely in case of a hose rupture.

How to Use GasFuse

How to connect

Gasfuse screws directly into an LPG cylinder. The hose and regulator from your appliance then screws into Gasfuse.

For Major Leaks

If there is a major hose rupture, for example from a fire at the appliance or the hose detaching, you don’t need to do anything – Gasfuse will simply shut off whether you’re there or not. When the problem is fixed, just pump the gauge 3-4 times, and the gas will start flowing again. If the problem hasn’t been fixed properly and the hose ruptures again, Gasfuse will shutoff once more.

For Leak Detection

You can determine if there are any leaks in any gas connection that has a Gasfuse attached. Turn the appliance off, and the LPG cylinder on. Pump the gauge 3-4 times to let the gas flow, then turn the LPG cylinder off. Now watch the gauge for a few minutes – if there is any leak, the needle on the gauge will move.

As a Low Gas Indicator

Gasfuse tells you when you need to change cylinders or get a refill. Turn your appliance on and run it for a few minutes. The gauge is clearly marked and colour coded. When the needle falls into the red zone marked refill, you know you’ll be needing more gas soon.

Gas Safety

We go beyond the standard

By law, all barbecues sold in Australia must comply with Australian Standard AS4557-2004. A change was introduced recently which requires all new barbecues to have a device fitted which either shuts off or limits the flow of gas.. The actual wording of the clause is

2.4.1.2 Means to automatically shut off or reduce gas flow

Means shall be provided to automatically shut off or reduce the flow of gas using a device, upstream of the hose that will operate at a flow of not more than 3.0 cu.m/hr (air equivalent at standard conditions, see Clause 1.2.66) with 700 kPa supplied to the inlet of the device.

In the case of a device that reduces the flow of gas, the bypass shall not allow a flow greater than 0.3 m3/h (air equivalent at standard conditions, see Clause 1.2.66) with 700 kPa supplied to the inlet of the device.

The means shall-
(a) be integral with the regulator assembly;
(b) be designed in a way to prevent consumer disassembly without the use of specialized tools or undue force; and
(c) include either manual or automatic reset without the need to disconnect any part of the gas piping system, including the cylinder connection.

(Implementation date 1 January 2005)

This clause recognizes that gas safety is a more serious issue now than any time in the past. Gasfuse? does more than meet the minimum requirement of the standard. It meets or exceeds the most most stringent requirement for total shutoff.

The exact implementation date of this clause is under review.
