FAQs

What type of gas can this valve be used with?

This valve is generally suitable for natural gas and LPG. Always verify compatibility with your specific gas supply and appliance.

What does the 'threaded collar' feature do?

The threaded collar allows for easier and more secure attachment of the valve to the gas supply pipe, simplifying the installation process.

What are the shaft dimensions?

The shaft diameter is 8x6.5mm, and the shaft length is 22/15mm. The knob shaft length is 15mm.

Does this valve come with everything needed for installation?

Yes, it is supplied with nuts, olives, and connectors required for a standard installation.

How do I connect the thermocouple?

The thermocouple connects to the designated M8x1 port on the valve.

What is the purpose of the bypass nozzle?

The bypass nozzle, with a size of 0.35 mm, helps in regulating the pilot flame, allowing for fine adjustments to gas flow.

Can this valve be used for appliances without a pilot light?

While it is designed with a pilot connection, its primary function is gas flow control. It can be used in systems without a pilot light, provided the gas flow regulation is still required.

Troubleshooting

Valve not opening or closing properly

Check for obstructions in the shaft mechanism. Ensure the knob is correctly seated and turned fully.

Gas leak detected at connection points

Turn off the gas supply immediately. Re-tighten the fittings, ensuring olives are correctly seated. Replace any damaged olives or connectors.

Pilot light will not ignite or stay lit

Verify the thermocouple is securely connected to the M8x1 port. Check the pilot gas line for blockages. Ensure the bypass nozzle is not clogged.

Inconsistent gas flow

Ensure the bypass nozzle (0.35 mm) is clear. Verify gas pressure is within the appliance's specified range. Check for any kinks or blockages in the gas tubing.

Setup, Compatibility & Care

Setup:

  2. Identify the correct gas input and outlet ports (both M16x1.5).
  3. Connect the gas line to the appropriate port using the provided nuts and olives, ensuring a tight seal.
  4. Attach the thermocouple to the M8x1 connection.
  5. Connect the pilot line to the 6mm pilot connection if applicable.
  6. Install the control knob onto the 8x6.5mm shaft.
