Storing Your Grill

Cleaning the Burner Assembly

Follow these instructions to clean and/or replace parts of
burner assembly or if you have trouble igniting grill.

1. 

Turn gas OFF at control knobs and LP cylinder.

2.

Remove cooking grates and heat diffusers. 

3.

Remove carryover tubes and burners.

4.

5.

Carefully lift each burner up and away from valve openings.

We suggest three ways to clean the burner tubes. Use the one 

easiest for you.

(A) Bend a stiff wire (a light weight coat hanger works well) 

into a small hook. Run the hook through each burner 
tube several times.

(B) Use a narrow bottle brush with a flexible handle (do not 

use a brass wire brush), run the brush through each 
burner tube several times.

(C)

Wear eye protection: 

Use an air hose to force air into 

the burner tube and out the burner ports. Check each 
port to make sure air comes out each hole.

6.

Wire brush entire outer surface of burner to remove food 

residue and dirt.

7.

Clean any blocked ports with a stiff wire such as an open 

paper clip.

8.

Check burner for damage, due to normal wear and corrosion 

some holes may become enlarged. If any large cracks or 
holes are found replace burner.

VERY IMPORTANT: Burner tubes must reengage valve

openings. See illustration at right.

 9. Attach electrode to burner.
10. Carefully replace burners.
11. Attach burners to brackets on firebox.
12. Reposition carryover tubes and attach

to burners. Replace heat diffusers and
cooking grates.

CAUTION

• Clean cooking grates.
• Store in dry location.
• When LP cylinder is connected to grill, store outdoors in a

well ventilated space and out of reach of children.

• Cover grill if stored outdoors. Choose from a variety of grill 

covers offered by manufacturers.

• Store grill indoors ONLY if LP cylinder is turned off and 

disconnected, removed from grill and stored outdoors.

• When removing grill from storage, follow “Cleaning the 

Burner Assembly” instructions before starting grill.

Important: 

Always ensure that the venturi burner tubes are clean. A 

venturi burner tube has a narrow area in which spiders tend to build 
nests.

Spiders or small insects have been known to create “flashback” 
problems. The spiders spin webs, build nests and lay eggs in the 
grill’s venturi tube(s) obstructing the  flow of gas to the burner. 
The backed-up gas can ignite in the burner tube behind the 
control panel. This is known as a flashback and it  can damage 
your grill and even cause injury.

To prevent flashbacks and ensure good performance the burner 
and venturi tube assembly should be removed from the grill 
and cleaned before use whenever the grill has been idle for an 
extended period.
