A step-by-step guide to checking the Dome Gen 2 Series Gas Hose for natural gas, from verifying the part number to leak testing and safe connection.

Quick answer

The Dome Gen 2 Series Gas Hose - Natural Gas is the correct hose for connecting your Dome Gen 2 to a natural gas line. Before installing, confirm you have the natural gas version, inspect the hose for damage, and perform a leak test with soapy water at every connection. If you are unsure whether this is the right part, check your product manual first.

Why the natural gas hose is different

Natural gas and propane require different hoses because they operate at different pressures and have different connection standards. The Dome Gen 2 Series Gas Hose - Natural Gas is designed specifically for a natural gas line, so it should not be used with propane. If you are converting your oven or replacing a lost or damaged hose, using the wrong type can create a serious safety risk.

This hose is included as standard with the original Dome Gen 2 product. Gozney notes that buying an additional spare is only necessary if the original is lost or damaged. That means most owners will only need this part for replacement, not for a new install.

Tools and checks before you start

You will need two adjustable wrenches, a leak-detection solution (soapy water or a commercial leak test spray), and a clean rag. Do not use thread tape or sealant unless your local gas code or the manual specifically calls for it, as some fittings rely on a rubber gasket or flare connection.

Before touching any connection, turn off the gas supply at the shutoff valve. If you smell gas at any point, stop immediately and follow your gas supplier's emergency procedure.

Step-by-step fit and safety checks

Confirm you have the natural gas hose: Check the product label or packaging to ensure it is the Dome Gen 2 Series Gas Hose - Natural Gas. If you are replacing a hose, compare the old and new fittings. Common mistake: assuming a propane hose will work on natural gas. They are not interchangeable. If the label says propane, stop and source the correct natural gas hose.
Inspect the hose and fittings: Run your hand along the hose to feel for cracks, cuts, or stiff spots. Check that the metal fittings are free of debris and that any rubber gasket is present and not cracked. A damaged gasket can leak even if the hose looks fine. Replace the hose if you find any damage. Do not try to repair it.
Turn off the gas supply: Close the shutoff valve on your natural gas line. If you cannot find the valve or are unsure how to isolate the supply, call a licensed gas fitter before proceeding. Never work on a live gas line. No gas flow means no surprises.
Connect the hose to the oven and gas line: Hand-tighten the fittings first, then use two wrenches to tighten them fully—one to hold the fitting steady, one to turn the nut. Do not overtighten, as this can damage the gasket or strip threads. Follow the manual for the correct orientation and any required support. A snug, not brutal, fit is what you want.
Perform a leak test: Turn the gas supply back on. Brush soapy water on every connection point—at the oven inlet, the hose ends, and the gas line. Watch for bubbles. If bubbles appear or you smell gas, turn off the supply immediately and tighten or reconnect as needed. If the leak persists, contact a professional. No bubbles means the connection is gas-tight.
Check for strain and routing: Make sure the hose is not kinked, stretched, or touching hot surfaces. It should have a gentle curve and be protected from sharp edges. A hose under tension can work loose over time. Route the hose so it can move slightly without pulling on the fittings.
Record the installation date: Write down when you installed the hose and keep it with your oven records. Gas hoses can degrade over time, and knowing the age helps you decide when to replace it. Inspect the hose periodically for signs of wear. A simple note now can prevent a problem later.
