How To Adjust The Air Shutters On Your Gas Grill Burners If The Flames Are Burning Yellow
As always, consult your Owner’s Manual to easily locate any part of your grill, including the air shutters, for replacement.
Adjusting the burner intake is one of the easiest ways to improve your gas grill’s efficiency. An air adjustment shutter at the burner’s base allows you to adjust the amount of air mixed with gas.
Too little air, and you’ll get a low yellow flame. If the flame looks like it’s floating above the burner, there is too much air coming through.
The correct amount of air should give you consistent, approximately 1-inch blue flames with a yellow tip across the entire burner, and the flames should touch the burner.
The air adjustment shutter can be found at the bottom of the burner. Or on venturi tubes, it can be located at the base of the tubes.
Adjust Your Grill’s Air Shutters By Following These Steps:
Step 1: Locate the set screw by the metal shutter at the end of the burner.
Step 2: Loosen the screw to allow the shutter to slide open or closed. Leave it half open for propane gas, or a quarter of the way open if you’re using natural gas.
Step 3: Ignite the grill to see if the burner flames are blue with yellow tips.
Step 4: Once the flames are burning blue, tighten the screw to keep the shutter in place.
How To Clean Your Gas Grill’s Burners
If there are spots without flames along your burner, then you probably have a clogged burner. Check your burners for clogged holes. You can use a straightened paper clip to unblock them.
Step 1: Check your manual for instructions on how to remove your burners correctly. Once the burners are taken off, you’re ready to clean your grill.
Step 2: Use a burner cleaning rod or a small-diameter bottle brush to clean out debris inside the burner tube.
Step 3: Scrub the burners with a nylon brush on the outside of the burner to remove food debris and dirt.
Step 4: Check your manual for instructions on how to reattach your burners correctly.

Common Causes Of Dirty Grates & Burners On A Gas Grill
Every time you use your grill - food particles, oil, marinade, sauces, fat and grease are left on the grill. They can also drip down onto your flame tamers and burners.
It’s advisable to clean your grill after every use, once it’s cooled down.
The Importance Of Cleaning Your Gas Grill Before Every Use
- Regular cleaning gives you a chance to make sure that your gas grill is working properly.
- If you don’t empty and clean it often, the grease catcher on your grill could easily overflow. Not only is this a fire hazard, it can also stain the concrete your grill is standing on.
- If you don't clean your grill, you expose fresh foods to old food particles and residue. The leftover grease, fat, and pieces of meat will burn, changing the taste of your food.
- When old meat and fat is burnt into charcoal in your grill, the smoke taints your food with cancer-causing carcinogens.
- Leftover, accumulated grease is an ideal breeding ground for mold. Yuck!
- If you don’t use your grill for a while and there are leftover bits of meat and grease attached to it, it will attract critters like rats and mice that will make their home in your grill.
