Can the Big Green Egg® ConveGGtor (platesetter) be used with the Large Adjustable Rig?  No, the Large Rig is not designed to be used in conjunction with the Big Green Egg® ConveGGtor.

Do I use my grill's 18" grid with the Adjustable Rig?  Yes, your 18" Big Green Egg® cooking grid sits atop the Rig and creates a raised grid set-up.  

What size objects fit inside the Adjustable Rig?  Any round object (ceramic stone, pan & grid) must have a diameter less than 16-3/4".  To slide between the front brackets, the object's width must be less than 13-1/8".

What do settings low, middle and felt line mean?  These 3 settings correspond to the three notches that run vertically on the Rig brackets. The settings measure the distance from the fire ring to the notch.  The lowest setting is 1.5 inches above the fire ring.  The middle setting is 3 inches above the fire ring.  The felt line setting is 4.5 inches above the fire ring, the felt line.  The top ring on the Rig is 6" above the fire ring, approximately 2" above the felt line.  

Can the Adjustable Rig be set-up to create an indirect (ConveGGtor like) configuration?  Yes, with the addition of either a 13", 15", 16", Oval or Half Ceramic Stones, the Adjustable Rig can be set-up to create an indirect smoking (barbeque) set-up.  We recommend 2 - 15" Half Round or 13"x17" Oval Stone as your primary barbeque stone.

Can I use Big Green Egg's® 14" pizza stone?  Big Green Egg's 14" pizza stone can be used with the Rig but not with the Large Spider.  Only our 13" Round Stone is recommended for the Spider.

Where do I store the equipment?  We recommend you store the pieces in your grill on the Adjustable Rig.  Let the Spider hang in the fire ring. 

Do I need to clean the equipment?  Other than the cooking grids, there is no reason to spend time and energy cleaning the equipment.  Do not clean the ceramic stones with liquids or soap.  Wrap drip pans in foil for easy clean up.

Can you put Big Green Egg's cast iron grid atop the Rig?  We do not recommend putting the cast iron grid on the Rig's top ring, as there is nothing to hold it in place.

Can the Rig sit on the 18" egg grid?  Yes, the Rig can sit on the 18" egg® grid but the grid needs to be on the fire ring.  The Rig can sit on the large, 18" cast iron grid too.

        A Few Tips


        Every now and then, we fail to hit the target grilling temperature at the grid.  If you are new to ceramic cooking, a couple of reasons for missing the temperature can be:

        • miss the settings on the lower slider or upper daisy wheel;
        • forgot to mix old and new lump; 
        • let the temperature run up; or 
        • try to stretch the back-end of a long barbeque cook with a quick grilling cook.  

          So, if you find that you missed the target cooking temperature at your initial grid height, simply move a grid up or down the Rig for a quick fix.  Remember this, it will come in handy!

           One of the cool features of the Adjustable Rig is how fast it and its contents can be removed from the ceramic grill.  When feasible, we recommend setting all the pieces (grids, stones, pans) directly on the Rig.

          The first step in removing the Rig is to have your landing area ready and close by.  The second step is to wear adequate personal protection.

          To remove the Adjustable Rig, grab under the Rig's upper ring and lift the Rig up and out.  Keep the Rig level.  Remember, these items are hot, so it is worth repeating, have the landing area close by and take the necessary safety precautions to protect yourself and other equipment. 

          You may wonder how fast is the move!  There is a good chance it took you longer to read this one "Tip" than it will take you to lift out the Rig.

           When foiling ribs, best is bone end up to minimize your chances of tearing the foil.  A 20" pan under the Rig makes for easy clean up with accidental spills in your landing area.  As a note, our 18" Stainless Round Drip Pan is too small.  20" is recommended.

          The Oval grid is 12.75" wide by 17.5" long.  So, it is possible to drop wood chunks past the grid at all three Levels.  The wood chunk is 1-1/2 inches thick.

          Sometimes with direct grilling, the lump burn creates hot spots across the grid.  You can minimize the effects from the hot spot by spinning the round grid(s).  To spin the grid, just set the tongs at grid center and turn.

          To slow a cook down, you can change from a direct to an indirect set-up by adding a stone under the grid.  If you think you may change over during a cook, we recommend setting the Crossbars before starting the cook.

          The chicken leg cook, pictured below, started direct with grid temperatures over 375 degrees.  After rendering the fat for a short time and charring the skin, the 16" Round Stone was added at the middle Rig setting.  This took the direct heat off the legs and allowed them to "roast" till done.  Similar cooks can be done with our other stones, including our Half Stones for a half direct & half indirect set-up.

          If you are one who constantly worries about running out of lump or lives in a very cold climate, you can overfill the Large Big Green Egg® fire ring to fuel a low & slow cook.  The photo, bottom left, shows the indirect set-up on the middle Rig setting.  Guess if you need more lump, you could set the stone at the upper setting.  DO NOT use this much lump for grilling or high temperature cooks.

          For jerky, it is feasible to load a grid on each Level.  The set-up requires 3 Crossbar pairs and 3 grids.  Pictured above right is the set-up with 3 oval grids.  The 18" egg® grid sits atop the Rig for additional space.  Spacing between grids is approximately 1.5 inches.

          If you are not using a Crossbar during a cook or have an extra set, one can be used as a wiggle rod to shake the ash from the Big Green Egg® lump grate during a cook.  Slip the Crossbar through the lower slider opening, hook into one of the open grate holes and lightly push/pull.  The motion will shake the ash from the grate openings, improving airflow.
