WARNING!

 Always wear protective gloves and safety glasses when servicing your grill.

WARNING!

 To avoid the possibility of burns, maintenance should be done only when the grill is cool. 

Avoid unprotected contact with hot surfaces. Ensure all burners are turned off. Clean grill in an area where 

cleaning solutions will not harm decks, lawns, or patios. Do not use oven cleaner to clean any part of this 

gas grill. Do not use a self-cleaning oven to clean cooking grids or any other parts of the gas grill. Barbecue 

sauce and salt can be corrosive and will cause rapid deterioration of the gas grill components unless cleaned 

regularly.

Maintenance / Cleaning Instructions

Note

: Stainless steel tends to oxidize or stain in the presence of chlorides and sulfides, particularly in coastal 

areas and other harsh environments, such as the warm, highly humid atmosphere around pools and hot tubs. 

These stains could be perceived as rust, but can be easily removed or prevented. To provide stain prevention 

and removal, wash all stainless steel surfaces every 3-4 weeks or as often as required with fresh water and/or 

stainless steel cleaner. 

We recommend this gas grill be thoroughly inspected and serviced annually by a qualified service person.
At all times keep the gas grill area free from combustible materials, gasoline and other flammable vapors and 

liquids.  Do not obstruct the flow of ventilation and combustion air.  Keep the cylinder enclosure ventilation 

openings (located on the cart sides and at the front and back of the bottom shelf) free and clear from debris.

WARNING!

 Turn off the gas at the source and disconnect the unit before servicing. To avoid the possibility 

of burns, maintenance should be done only when the grill is cool.  A leak test must be performed annually and 

whenever any component of the gas train is replaced or gas smell is present.

1/2” (13mm)

Combustion Air Adjustment: 

(This must be done by a qualified gas installer.)  The air shutter is factory set and 

should not need adjusting under normal conditions. Under extreme field conditions, adjustments might be 

required.  When the air shutter is adjusted correctly the flames will be dark blue, tipped with light blue and 

occasionally yellow.

•  With too little air flow to the burner, the flames are lazy yellow and can produce soot.
•  With too much air flow, the flames lift erratically and can cause difficulties when lighting.

Adjusting the air shutter:
1. Remove cooking grids and sear plates and leave lid open.   
2.  Loosen air-shutter lock screw located at the mouth of the burner and open or close air shutter as required.  

The normal opening settings are:
 

Main Tube Burner  

Propane  15/64” (6mm)   

Natural  1/8” (3mm) 

*Infra-Red burners have no air adjustment.  
3. Light the burners and set to high. Visually inspect burner flames. When the shutters are set correctly, turn 

burners off, tighten locking screws, and replace removed parts.  Ensure that the insect screens are installed.
