the gas   (OFF) and open lid to let the gas clear for about 5 minutes 

before re-lighting.

2.  Turn all control knobs clockwise to the   (OFF) position.

A “poof” sound is normal as the last of the LP gas is burned.

Direct Cooking 

Cooking directly over hot burners is ideal for searing in juices and grilling food requiring 
less than 25 minutes of grilling time, such as steaks, hamburgers, hot dogs, chicken parts, 
vegetables and fruit.

2.  Close lid and preheat grill on   (HIGH). 
3.  Wear protective gloves and use long handle tongs to place food onto cooking grids above the 

lit burners.

4.  Adjust controls to desired flame height. 
5.  With lid open or closed, cook until desired internal food temperatures are achieved. 
6.  Turn grill OFF by turning the LP gas tank valve to “CLOSED”. Burn off remaining gas in lines 

by waiting 15 seconds then turn all burner controls to the   (OFF) position. A “poof” sound is 
normal as the last of the LP gas is burned.

Indirect Cooking 

Not cooking directly over hot burners is ideal for slow cooking and foods requiring more than 
25 minutes such as most roasts, loins, chops, whole chickens, turkey, fish and baked goods. 
1.  Open lid and ignite the desired burner(s) per lighting instructions in owner’s manual. 
2.  Close lid and preheat grill on   (HIGH). 
3.  Wear protective gloves and use long handle tongs to place food onto cooking grids above the 

un-lit burners.

4.  Adjust controls to desired flame height. 
5.  With lid closed, cook until desired internal food temperatures are achieved. 
6.  Turn grill OFF by turning the LP gas tank valve to “CLOSED”. Burn off remaining gas in lines 

by waiting 15 seconds then turn all burner controls to the   (OFF) position. A “poof” sound is 
normal as the last of the LP gas is burned.

Controlling Flare-ups

  Caution: Putting out grease fires by closing the lid is not possible. 

 

•  Do not use water on a grease fire. This can cause the grease to 

splatter and could result in serious burns, bodily harm  or other 

damage. If a grease fire develops, turn knobs 

 (

OFF) and LP gas 

tank valve “CLOSED”.

 

•  Do not leave grill unattended while preheating or burning off 

food residue on   (HIGH). If grill has not been regularly cleaned, a 

grease fire can occur that may damage the product.

  WARNING: When cooking, fire extinguishing materials shall be readily 

accessible.  In the event of an oil/grease fire, do not attempt to 

extinguish with water.  Use type BC dry chemical fire extinguisher or 

smother with dirt, sand or baking soda.

Flare-ups are a part of cooking meats on a grill, and adds to the unique flavor of grilling. 

Excessive flare-ups can over-cook your food and cause a dangerous situation for you 
and your grill.

 

Important: 

Excessive flare-ups result from the build-up of grease in the bottom of your grill. 

Minimize Flare-ups:

1. Trim excess fat from meats prior to cooking.
2. Cook high fat contents meats on   (LOW) setting or indirectly.
3.  Ensure that your grill is on hard, level, non-combustible surface and the grease is allowed to 

drain into grease cup.

3.  Use the upper cooking grid (warming rack) for keeping cooked food warm, toasting breads or 

cooking delicate foods in aluminum foil pouches. 

4.  Use the side burner of this appliance like a normal kitchen range for boiling, sautéing or 

frying. 

5.  To keep food from sticking to the grids, spray or coat with cooking oil before lighting. 
6.  To reduce flare-up keep grill clean, use lean cuts of meat (or trim fat) and avoid cooking on 

very high temperatures. 

7.  Place delicate foods like fish and vegetables in aluminum foil pouches and indirect cook or 

place on upper cooking levels (warming rack).  

  WARNING: Never cover entire cooking area with aluminum foil.

8.  To avoid losing natural juices, use long handled tongs or spatulas instead of forks and turn 

foods over just once during cooking.  

9.  When direct cooking adjust your burners to different levels so foods can be prepared to 

different internal temperatures in the same time frame. 

10.  When indirect cooking roasts and larger cuts of meat, place meat onto a roasting rack 

inside a heavy gauge metal pan. Place pan over the un-lit burners.

11.  Try water pans to reduce flare-ups and cook juicer meats. Before starting grill remove 

cooking grids and place a heavy duty shallow pan directly on heat plates. Fill half way with 
water, fruit juices or other flavored liquids. Replace cooking grids and position food over the 
loaded pan.

12.  Enhance food flavors by using wood chips in smoker boxes or aluminum foil pouches. 

Follow the wood manufacturer’s instructions. 

13.  Grill baskets, vertical poultry holders and other accessories can enhance your experiences, 

reduce cooking times and aid in clean-up.

14.  Clean cooking grids and racks after every use with a quality grill bush designed for your 

grid material. Wear protective gloves and gently remove the build-up while grids are hot. 

15.  After every use, allow grill to cool. Then protect clean cooking grids with a light coat of 

cooking oil, empty grease pan, wipe outside surfaces with a suitable kitchen cleaner and 
protect surfaces with a quality cover that properly fits your grill. 

16.  Watch barbecue themed TV shows or purchase related barbecue cookbooks to learn more 

interesting tips like –
