What's in the Box

• 1 x Honeywell 3/4" Straight Flange
• 1 x O-ring
• 2 x 9/64" Hex Screws
• 1 x Dust Plug

Using It on the Job

1. Isolate System: Always ensure gas supply is shut off and locked out at the main valve before beginning any work on gas components.
2. Remove Old Flange (if applicable): Carefully detach the existing flange and gas valve, ensuring no debris enters the gas line.
3. Inspect Mounting Surface: Clean the mating surface on both the gas valve and the gas line to ensure a smooth, debris-free seal.
4. Position New O-ring: Place the new O-ring from the kit correctly into its groove on the flange or valve. This is critical for a leak-free connection.
5. Install Flange: Align the new Honeywell flange kit with the gas valve and the piping. Insert the 9/64" hex screws and tighten them evenly, but don't overtighten to avoid stripping threads or deforming the O-ring.
6. Leak Check: Once assembled, restore gas supply cautiously and perform a thorough leak test using an approved leak detection solution or an electronic leak detector around all connections.

Limitations & Safety Notes

• This flange kit is designed for specific Honeywell gas valves and may not fit other brands or models. Verify compatibility before use.
• Any work on gas appliances or systems must be carried out by a currently licensed gas fitter in Australia.
• Always follow Australian Standards and Safe Work Australia guidance for gas installations and maintenance.
• Ensure screws are tightened to the manufacturer's recommended torque specifications to prevent leaks or damage.

Tradie Pro Tip

When working with gas valves, always have a spare O-ring kit or complete flange assembly on the van. You never want to reuse old seals, and having a fresh one prevents callbacks and ensures the system is sealed tight from day one.

Pair With

Pair this flange kit with your preferred gas leak detector and a good quality set of hex keys for complete confidence during installation and servicing of commercial gas systems. Don't forget thread sealant for any other threaded connections.
