A Bertazzoni Range Flame That Gets Pulled Sideways by Your Hood

Many Houston remodels add a powerful hood over a gas range. It looks like a great upgrade, until the burner flames start leaning toward the hood or blowing out whenever the fan is on high.

Why it happens

A strong exhaust fan pulls air out of the house. If nothing lets fresh air back in, the house goes slightly negative, and air rushes toward the opening it can find, sometimes right across your burners. Tightly sealed newer homes show this more.

A quick test

1. Turn the hood fan to its highest speed with all windows closed.
2. Light a burner and watch the flame.
3. Now open a nearby window and look again.

If the flame settles once the window is open, the burner is fine and the house needs makeup air. Talk to your hood installer or contractor about that.

When it is the burner

• The flame lifts or goes out even with the fan off
• Only one burner misbehaves while the others look steady
• The cap sits crooked, or ports are visibly clogged
• Flames are yellow or tipped with orange

A dirty cap or port blocks gas flow and can make a burner more sensitive to drafts. Cleaning it, as covered in our care guides, often solves it.

What not to do

Do not keep relighting a burner that blows out repeatedly. Unburned gas can collect, and the smell is a signal to stop. Turn the knob off, ventilate the room, and wait before trying again.

Also avoid running the hood at full speed for light simmering. A lower setting handles most meals, and the flame stays steadier.

For help with burner behavior, visit range repair and check our service area list.

When you call, mention what the fan was doing, and our technician will arrive within a three-hour window ready to test the burner both ways.
