Regardless of which burner cleaning procedure you 
use, we recommend you also complete the following 
steps to help prolong burner life.

1. Use a fiber pad or nylon brush to clean the entire 
outer surface of each burner until free of food residue 
and dirt.

2. Clean any clogged ports with a stiff wire, such as 
an open paper clip.

3. Inspect each burner for damage (cracks or holes) 
and if such damage is found, order and install a new 
burner. After installation check to ensure that gas 
valve orifices are correctly placed inside the ends of 
the burner tubes.

Cleaning and Maintenance

Cleaning Burner Tubes and Burner Ports

To reduce the chance of “FLASH-BACK” the procedure 
below should be followed at least once a month in late 
summer or early fall when spiders are most active or 
when your grill has not been used for a period of time.

1. Turn all burner valves and gas tank valve to off 
position.
2. Detach the LP gas regulator assembly from your gas 
grill.
3. Remove cooking grids, flame tamers, and grease 
tray from the grill.
4.  Remove the screws from the underside of each 
burner and lift the burners up and away from the gas 
valve orifice. 
5. Using a bent stiff wire in the shape of a hook , air 
hose or a bottle brush, run it through the burner tube 
and inside several times to remove any debris. 
6. Replace burners, see illustration below.

Step 1. Locate the burner onto the orifice.

Step 2. Secure the main burner on the back wall of fire 
box with 2 screws. 

WARNING

The location of the burner tube with respect to the 
orifice is vital for safe operation. Check to ensure 
the orifice is inside the burner tube before using 
the gas grill. If the burner tube does not fit over the 
valve orifice, lighting the burner may cause 
explosion and/or fire.
