Gas Bayonet Fitting – Gas Bayonet Hose – Connect & Disconnect Gas Bayonet

A gas bayonet fitting (gas fitting) is used to connect a gas appliance to the gas bayonet wall socket or floor mounted female gas fitting.

The gas bayonet hose (gas heater hose) connects the gas bayonet fitting (gas fitting) to the gas bayonet heater or other appliance.

The gas bayonet fitting (gas fitting) consists of a male and female gas bayonet fitting.

Gas bayonet installation is like a bayonet light globe.

The most popular style of gas heater in Australia is the Portable Gas Bayonet Heater.

A portable gas bayonet heater connects to your home gas supply by means of a gas bayonet hose (gas heater hose) with a brass push & twist-to-lock gas bayonet fitting (gas fitting) for gas bayonet installation.

Gas Bayonet: Gas Bayonet Fitting, Gas Bayonet Hose & Gas Bayonet Wall Socket

Gas bayonet fittingA gas bayonet or gas bayonet fitting (gas fitting) provides a method of attaching a gas bayonet heater to a gas bayonet wall socket with a gas bayonet hose (gas heater hose). All are part of the gas bayonet system of gas bayonet fitting components.

A male gas bayonet fitting (gas fitting) connects a gas appliance — typically a gas bayonet heater — to a fixed female gas bayonet wall socket or floor mounted female gas bayonet fitting, attached to the gas supply. The male gas bayonet fitting is attached to the end of the gas bayonet hose (gas heater hose).

The female gas bayonet is attached to the gas supply line and affixed to the wall or floor.

You connect a gas bayonet by pushing in and twisting clockwise to lock it in place.

To disconnect, you push in slightly, turn anti-clockwise and then pull the male gas bayonet fitting (gas fitting) out.

Gas bayonet hoseGas bayonet fitting (gas fitting) for a gas bayonet heater connect the gas bayonet heater to the gas source.

The gas bayonet installation includes the female gas bayonet connected by gas pipe fittings to the gas bottles or natural gas bayonet heater connections.

Female gas bayonet installation can be into a wall or through the floor

Most gas bayonet heater models have an electrical connection to power the fan, igniter and control board.  Some models of radiant gas bayonet heater do not require electricity.

Female Gas Bayonet Wall Socket

Female Gas Bayonet Fitting

The female gas bayonet wall socket or floor socket is permanently attached to your wall or floor and the supply gas line is connected to it through the wall or floor.

The female gas bayonet has two locking lugs that are used to engage the male gas bayonet fitting (gas fitting) and lock it in place.
 
A rubber O-ring seals the connection.
 
It also contains the on/off gas valve that is automatically actuated when a male gas bayonet fitting is fully inserted and locked.

Gas Bayonet Hose (Gas Heater Hose) and Male Gas Bayonet Fitting

Male Gas Bayonet Fitting

The male gas bayonet fitting (gas fitting) is affixed to the end of the gas bayonet hose (gas heater hose), which is attached to the portable gas bayonet heater.
 
The male gas bayonet has two push-and-twist slots for engaging the two locking lugs on the female gas bayonet socket.
 
It also has a protrusion that pushes on and opens the automatic gas valve, when the male gas bayonet fitting (gas fitting) is fully inserted and locked in place.

Inspect & Clean the Gas Bayonet Fitting

It is important that both gas bayonet fitting (gas fitting) ends be clean and free of any dirt or debris before trying to connect them.
 
Pieces of dirt and debris can cause the connection to leak.
 
Needless to say, if you inspect the connectors and discover any damage, do not attempt to connect them.
 
You should also periodically inspect the gas bayonet hose (gas heater hose) for any damage or degradation.
 
Call your gas fitter to make any needed repairs.

Gas Bayonet Installation

A licensed gas fitter must always do the gas bayonet installation.

Female gas bayonet fitting for installationThe female gas bayonet fitting (gas fitting) is installed through a wall or the floor and is connected to the gas bottle piping.

Hence, it involves significant plumbing work, which should only be performed by certified professionals.

The male gas bayonet installation is just a matter of attaching it to the end of a gas bayonet hose (gas heater hose), typically done by the gas bayonet hose manufacturer.

Various gas bayonet fitting (gas fitting) components may be required to properly connect the gas bayonet cooker or gas bayonet heater to the gas bayonet, including:

  • Gas bayonet hose (gas heater hose)
  • Gas bayonet wall socket: angled or straight in brass, chrome or stainless steel
  • Gas bayonet floor socket
  • Mounting bracket

Connecting a Gas Bayonet

Connecting the Bayonet Fitting

The actual physical act of connecting the two gas bayonet fitting (gas fitting) ends is very similar to the changing of a bayonet light globe.

The male gas bayonet fitting is inserted into the female gas bayonet fitting, with the locking lugs aligning with the engagement slots.
 
You push in and twist clockwise to lock it in place.
 
Please note that you need to push in rather firmly, as the gas valve spring is quite strong.

Disconnecting a Gas Bayonet

To disconnect a gas bayonet, you basically just reverse the process.
 
You push in slightly and turn anti-clockwise, to disengage the locking lugs, and then pull the male gas bayonet fitting (gas fitting) out.
 
There may be a small whiff of gas when you connect or disconnect the gas bayonet.  This is normal.

If You Continue to Smell Gas

However, if you detect a continuous leak, you should disconnect the gas bayonet immediately and inspect for dirt or damage, including to the O-ring inside the female connector.
 
In the extremely unlikely event that the female gas bayonet fitting (gas fitting) is still leaking, even after disconnection, you need to turn the gas off at the source.
 
In any situation where you have an ongoing problem, you should always call your gas fitter.
 
Never attempt your own gas repairs or allow any unqualified person to try to fix it for you.

Money Saving Tip for Summer Storage of a Gas Bayonet Heater

Use purpose made dust plugs or secure small plastic bags around the gas bayonet connectors to keep out dirt and insects, as they can clog the gas bayonet heater during the following season.
 
This could save you an expensive gas fitter repair bill!
