Bertazzoni Propane Range: Orifices, Flame Shape and Safe Setup

Many homes outside Houston’s city gas lines, from rural Montgomery County to lake houses, cook on propane. A Bertazzoni gas range can run on propane, but only when it has been set up for that fuel. Natural gas and propane burn at different pressures, so the small brass orifices under each burner must match what is feeding the range.

Signs the setup is wrong

• Tall, yellow-tipped flames that leave soot on the bottom of pans
• Flames that roar, lift off the burner, or blow out when you turn the knob down
• A sharp smell of unburned fuel when a burner first lights
• Burners that light unevenly around the ring

Any of these means the fuel and the hardware are not agreeing with each other. Turn the burners off and do not keep cooking while you wait.

What a proper conversion involves

1. Shutting off the gas supply and confirming the range is cool.
2. Swapping every burner orifice, including the oven and broiler, for the ones sized to propane.
3. Adjusting the regulator and the low-flame setting on each valve.
4. Lighting every burner and checking the flame color and shape.
5. Testing every fitting we touched for leaks.

Skipping the oven burner is a common mistake, and it is the one that causes bake problems later.

If you smell gas

Do not flip switches or hunt for the source. Leave the house, then call your gas supplier or the emergency line from outside. Once the supplier has cleared the home, we can check the range itself.

After a move or a tank refill, it also helps to watch the first lighting of each burner. A clean blue flame with a short, steady cone is what you want to see. Anything else is worth a visit before the next family dinner.
