Learn how to safely install and check the Dome Gen 2 gas regulator and hose for propane use. This guide covers fit, common mistakes, and when to replace.

Quick answer

To safely install the Dome Gen 2 gas regulator and hose, connect the quick-fit fitting to the oven inlet, attach the 30mbar screw-fit adaptor to your standard US propane tank, and perform a leak test before each use.

Why the Dome Gen 2 regulator and hose is a spare part

The Dome Gen 2 Series Gas Regulator and Hose is included with your oven as standard equipment. You only need to purchase this spare part if the original is lost or damaged. It is not an upgrade or accessory.

This hose uses a quick-fit connection on the oven side and a 30mbar screw-fit adaptor for a standard US propane tank. It is not designed for natural gas or non-US propane tanks.

Common mistakes to avoid

Do not use this hose with a natural gas supply. The 30mbar regulator is specific to propane. Attempting a natural gas conversion with this part will create an unsafe gas pressure mismatch.

Do not overtighten the screw-fit adaptor on the propane tank. Hand-tighten until snug, then use a leak test to confirm the seal. Overtightening can damage the tank valve or the adaptor threads.

Step-by-step installation guide

1. Check the part and manual: Verify you have the Dome Gen 2 Series Gas Regulator and Hose with the quick-fit connector and 30mbar screw-fit adaptor. Refer to your oven manual to confirm this is the correct part for your model and gas type. Using the wrong hose or regulator can cause unsafe gas flow. Always match the part number to your oven manual.
2. Connect the quick-fit fitting to the oven: Push the quick-fit connector onto the oven gas inlet until it clicks into place. Gently tug the hose to confirm it is locked. Do not use tools on the quick-fit connection. A common mistake is not pushing firmly enough. If the connector does not click, it may not seal properly.
3. Attach the screw-fit adaptor to the propane tank: Screw the 30mbar adaptor onto the standard US propane tank valve by hand. Turn clockwise until snug. Do not use a wrench or pliers. Overtightening can strip the threads or damage the tank valve. Hand-tight is sufficient.
4. Open the propane tank valve slowly: Turn the tank valve counterclockwise to open it fully. Wait 10 seconds for the regulator to stabilize before proceeding. Opening the valve too quickly can trip the excess flow device inside the regulator, reducing gas flow.
5. Perform a leak test: Mix a solution of equal parts water and dish soap. Apply it to all connections: the quick-fit joint, the screw-fit adaptor, and the tank valve. If bubbles appear, turn off the gas, tighten the connection, and test again. Never use a flame to check for leaks. If bubbles persist after retightening, replace the hose assembly.
6. Light the oven and check the flame: Follow your oven's lighting instructions. Observe the flame: it should be steady and blue with a yellow tip. If the flame is uneven or orange, turn off the gas and check for blockages or incorrect gas type. An unstable flame may indicate a gas pressure issue or an air leak. Do not use the oven until the flame is consistent.
