Kamado Stainless Steel Gas Burner System

After 6 years of R & D by Richard Johnson the Kamado Company is finally producing in house their own newly designed Stainless Steel Gas Burner System.

There are many new and unique patent applied for design features in this burner system. First and foremost, the stainless burner is now centered below the modified LumpsaverPlus. The modification is a flue or "shaft " centered under the basket which directs over 38,000 BTU's to rise from below the charcoal and into the heavy ceramic walled cooking chamber.

The unique stainless burner's design prevents ashes from above plugging the burner holes. With the new system, the charcoal is ignited in 3 or 4 minutes by the rising hot gases from the burner, up the flue, through "Firebox" hole (the "Grate" is removed), into the "LumpsaverPLUS." At the same time this ignited charcoal acts as a catalytic converter (secondary combustion) for any unburned gas.

The result is the fastest starting, cleanest burning and most odorless gas grill anywhere. In addition, there is a new safety feature. The burner is now mounted on the "Draft Door" allowing the burner to slide in and out on the stainless guides. The burner can now be easily and safely ignited from outside the Kamado.

The new burner fits in the exact location and uses the same guides as all Kamado "Draft Doors." There is no retrofit modification necessary, just simply slide the present draft door out and slide the new "Draft Door Burner" in.

There are no complicated valves, electronic ignition (that often didn't work) or components that rust or burn out.

The new burner is available for all 5 sizes of Kamados and uses the same basic design system. Both propane or natural gas can be accommodated. All components of the burner are 304 stainless except the brass control valve and carry a 5 year warranty, including a 100% satisfaction guarantee or your money back.

Price: For purchasing this Kamado Burner System at the time your Kamado is ordered the price is $150.00 complete with LumpsaverPlus Flue, Stainless Draft Door Burner, Brass Fuel Valve, Propane Regulator and Hose. Natural Gas has standard gas hose fitting to accept normal home gas pressure (11 1/2 column inch pressure). Shipping is included. If purchase is a retrofit the price is the same ($150.00) except shipping is extra. For retrofit for older Kamados with one piece firebox, the new firebox will be included at no charge. For customers who have purchased the older style gas burner and wish to change to the new burner system the price is $99.00 plus shipping. This will include the entire system mentioned above including stainless cover plates for the original burner hole.

Features:

Gas only, charcoal only or a combination of both gas and charcoal. Ideal to supplement gas with a little charcoal flavor without the need to rely solely on charcoal. Often a little "bump-up" of heat can be had by simply igniting the gas.
Heavy Stainless burner is hand made solely by the Kamado Company. We have furthered our goal of making what we sell. It is easy for us to guarantee that you will be more than satisfied because we can be assured of the quality, design, and performance. You can expect a lifetime of trouble free service.
Safe manual burner controls which allows for starting the burner while it is outside the Kamado. No igniter. We have followed the very latest High Technical engineering philosophy........... Keep It Simple!
38,000 BTU's blasting from under the charcoal "LumpsaverPlus" basket lights the charcoal and reaches 600 degrees in 6 minutes.
Burner slides in and out on two long 1/2 inch stainless rods to allow for easy and safe lighting from outside the Kamado.
The stainless burner, manifold and fuel control is welded to the "Draft Door" and uses the same stainless guide tubes runners as the present draft door and controls the airflow exactly the same way.
Perfect and simple gas retrofit. There is no modification necessary to change from charcoal only to gas/charcoal. Just remove the draft door and slide in the gas draft door, remove the firebox grate and put the new LumpsaverPlus with flue in the firebox. Note, if your Kamado #7 is over 3 or 4 years you might have the one piece firebox and grate. In this case you would need to replace your firebox with the newer two piece firebox with removable grate.
The heavy LumpsaverPlus with Flue is included with the purchase of the Kamado Gas Burner System. Also included is a new firebox if you have the earlier one piece firebox and grate..
The brass fuel control valve is unique and trouble free. There are no complicated valves or controls to become obstructed.
The temperature control is excellent in baking temperatures of 300 to 400 degrees. We still suggest using charcoal for smoking (200's or less).
There is no burner obstruction within the cooking chamber as with our earlier gas burner design.
There are no "hot spots" since the burner is far from the cooking grill(s).
Ashes can be removed by sliding the "draft door burner" out or by removing the LumpsaverPlus Flue basket from above.
Gas only operation can use lava rock in the LumpsaverPlus basket which allows secondary combustion or filter as gas rises through the superheated lava.
Gas only with lava provides a near-charcoal flavor that is often desired. Especially when smoking chips are placed on the outside of the Lumpsaver basket.
Retained heat in the heavy refractory ceramic walls provides 80% of the cooking temperature and gives the Kamado a "brick oven" smell and taste. Never a common fuel taste as other gas barbeques.
Preheating the walls with gas instead of charcoal will save hundreds of dollars because the BTU (heat output per pound) of gas is much cheaper than the BTU of charcoal. Frequent Kamado users will pay for their Kamado Burner System in months.
Easy to start, easy to use, efficient and safe gas burner = more frequent Kamado use = more friends over = more word of mouth = result is SALES for the Kamado Company!
Kamado #1 and #3 have smaller burners but take advantage of the same design principals and high temperature performance. Want a flash, char-rare steak in 6 minutes? Try a #3 gas/charcoal!

CAUTION: The gas and gas/charcoal combination can reach excessive temperatures. Since 95% of Kamado owners are serious "party" people..........don't forget to monitor the temperature of your Kamado!

Low Pressure LP Fuel Regulator: A UL listed regulator is used to reduce the gas pressure from the LP fuel tank to a safe pressure of 11 inches water column.

Flexible Fuel Hose: The fitting on the flexible fuel hose screws into the fuel valve and on the LP tank.

LP Fuel Tank: A customer-supplied LP approved fuel tank should be used. There are various size tanks that can be purchased to be used with the smaller Kamados. Normally a 20 pound tank is used for the #7 and #9,

Natural Gas : The natural gas version of the Kamado is the same as the propane version with these differences:

1) Larger burner jet is installed in the fuel control valve.

2) There is no tank needed as the barbecue is connected to your home gas line.

3) There is not a need for a regulator as the gas is regulated at your gas meter.

Note: Some localities may require that you use a separate natural gas regulator. If your area requires this you must obtain the regulator locally.

4) Different building codes in different areas of the country may require that you use specific materials for the gas line, i.e. rigid or flexible metal line instead of hose and also that you have a separate shut-off valve where the barbecue connects to your home gas piping.

BACKGROUND

Before now, over 100,000 Kamado owners could only use charcoal to fuel their grills. That has changed with the development of our KamadoGas grill. The KamadoGas grill allows you to burn propane or natural gas, and if desired, add charcoal and wood to the cooking chamber. Enjoy the convenience of using gas along with the flavor produced with charcoal! Like all Kamados, use this cooker for smoking items like ribs, salmon, and turkey or higher temperature grilling of steaks and your favorite dishes. You can even use the KamadoGas to bake pizza and bread! Food stays moist and cooks evenly, without the need for a rotisserie.

SETUP and OPERATION

SETUP:

Assembly The owner will attach the fuel hose to the 5/8 inch flare fitting on the fuel control valve and to the LP tank. The P.O.L. fitting is secured to the LP tank valve by tightening the fitting counter-clockwise.

Locate the LP tank on a level surface and at a safe distance away from the Kamado such that the fuel hose does not touch the barbecue.

Leak Check Do not ignite the burner when checking for leaks and do not use open flames to check for gas leaks.

Check all hose and valve fittings for leaks using a soap and water solution. The appearance of bubbles indicates leaks are present. If leaks are detected, retighten the fittings and recheck for leaks. Do not operate the Kamado with gas leaks.

Air/fuel Adjustment The air/fuel adjustment is set and tested at the factory and normally does not require adjustment.

OPERATION:

The versatility of the KamadoGas System and various fuel configurations will allow the operator to select one of the many desired methods of cooking. From low and slow, smoking, true ceramic oven, to flash cooking.

GAS OPERATION ONLY:

1. Lava rock is sometimes used in the LumpsaverPlus flue basket instead of charcoal or often a combination of charcoal and lava rock in the LumpsaverPlus Basket. We suggest some fine charcoal or smoke chips on the outside of the Lumpsaver for flavor. The charcoal can be added at any time.

2. Turn the control knob counter clockwise for low and clockwise for high. Positioning the knob to low will provide baking temperatures of approximately 300 to 350 degrees at the dome temperature gauge. Turning the fuel control knob to high will give temperatures of up to 400 degrees.

3. Opening the damper top further will decrease the temperature and reducing the damper top opening will increase the temperature.

4. Open the lid and place the food on the grill.

5. Monitor the temperature and adjust the control knob accordingly. Clockwise rotation increases the heat, counter-clockwise decreases the heat. Note that as the Kamado heats, less input is needed and the burner may be turned down. To assist in additional cooling, the draft door and damper top can be opened more.

6. The addition of charcoal will increase the temperature and decrease the time to “heat soak” the walls.

7. Gas operation is not intended for “low and slow” or extended cooking times below 250 degrees to prevent unattended use and possible wind blowing out the low flame.

CHARCOAL OPERATION ONLY AFTER LIGHTING WITH GAS:

1. Load the LumpsaverPlus basket and fine lump on the outside of the Lumpsaver with the desired amount of charcoal. The amount of charcoal normally does not determine the amount of temperature. It is the amount of air that is allowed to the charcoal after the gas is turned off. See the Kamado Charcoal manual and instructions. Often little or no additional charcoal is necessary after cooking and vents are closed to snuff the charcoal out.

2. Light the burner as described above.

3. Turn the control knob clockwise to the high gas flow setting. Both audio burning sounds and visual flame flickering through the one inch opening in the draft door. Also, within 60 seconds the temperature gauge will rise rapidly.

4. Close the lid after burner is lit.

5. Within 4 to 5 minutes the charcoal will be ignited and dome temperatures of approximately 600 degrees.

6. Exercise Caution to monitor the rapid temperature rise and turn the gas burner down or off to prevent excessive temperatures or those over 700 degrees.

7. After the desired temperature is stabilized slowly open and lock the lid as described in the Warnings section.

8. Place food items on the grill and shut the lid.

9. When completed the cooking, turn off the gas by first shutting the LP tank valve or natural gas valve, then rotating the control knob fully clockwise.

10. Adjust temperatures with charcoal using the draft door and the damper top. The general rule is more air more temperature with charcoal only. Once the charcoal in the firebox is burning, high temperatures can be obtained with the draft door open an inch or more and the damper top spun up 10 or more turns.

11. Note that with the new KamadoGas Burner System there is no difference in the operation or performance with this draft door burner in place. It operates as the original draft door as well as a burner.

COMBINATION GAS AND CHARCOAL OPERATION:

1. Pre-starting and starting is same as described above. Often, however, charcoal is added only for flavor.

2. The addition of charcoal initially will greatly decrease the time to heat the walls and obtain high temperatures in shorter times.

3. Turn the control knob clockwise to the high gas flow setting.

4. The damper top and draft door can be adjusted to assist in temperature control. However, do not adjust these components beyond that listed in the Warnings section.

TURING OFF:

1. Turn off the gas by first shutting the LP tank valve, then rotating the control knob fully clockwise.

2. Shut the draft door and shut the damper top to extinguish the charcoal.
