  3. Insert and Secure the Connection: Firmly push the male bayonet connector into the female socket until it reaches the end. You should feel a slight resistance as the bayonet lock engages.

  4. Turn Clockwise to Lock: Once fully inserted, turn the male connector clockwise approximately a quarter turn (90 degrees) to secure the bayonet lock. This ensures a gas-tight seal and prevents accidental disconnection.

  5. Safety Interlock (if applicable): Some bayonet connectors feature a safety interlock. When the connection is secured, the interlock automatically opens the gas flow, allowing the appliance to operate.


Disconnecting a Gas Appliance:

  1. Turn Off the Gas Appliance: Always turn off the gas valve on the appliance before disconnecting.

  2. Turn Counter-Clockwise to Unlock: Turn the male bayonet connector counter-clockwise approximately a quarter turn (90 degrees) to release the bayonet lock.

  3. Pull Straight Out: While holding the connector firmly, gently pull it straight out of the female socket.


Remember, never attempt to force the connection or disconnect a gas appliance if you suspect a leak. Always make safety your top priority and reach out to experts if you face any problems.


By following these simple steps and adhering to gas safety regulations, you can ensure the safe and efficient operation of your gas appliances using gas bayonets.
