Make sure to match the size of the prong with the size of the slot when plugging it into the control panel. This should not require much force. Connect the power cord last.


Operating Instructions



Pre-seasoning will rid your grill of chemicals and oils leftover by the manufacturing process, allowing them to burn off. PRE-SEASON GRILL PRIOR TO FIRST USE.
  1. Fill the hopper with charcoal approximately 1/4–1/2 full.
  2. Start grill following the START-UP instructions and set the temperature to 250°F (121°C) for 60 minutes.
  3. Set the temperature to 400°F (204°C) for 30 minutes.
  4. Shut down the grill following the SHUTDOWN instructions.
  5. Allow the grill to cool COMPLETELY.
  6. Using a napkin or cloth, rub a light coat of cooking oil on smoke + sear grates, warming/smoking racks, charcoal grate, and the inside of the grill lid and body.
  7. Repeat steps 3–6 at 350°F

Frequent seasoning prevents rusting. If rust occurs, clean with a steel brush, apply vegetable shortening, and heat as indicated above.


  1. REMOVE heat intake and air intake slides. (Refer to assembly step 21.)
  2. Open hopper lid and hopper ash door.
    • There is a safety switch at each of these doors that will prevent the fan from running when these doors are opened.
    • If charcoal remains from a previous cook, shake the charcoal grate to ensure all ash falls through to the ashtray.
    • Discard any ash from the ashtray.
  3. Fill the hopper with charcoal.
    • Approximately 16 lbs. of charcoal briquettes.
    • Approximately 10 lbs. of lump charcoal.
    • Never use fast light charcoal or lighting fluid.
    • If charcoal slips through the charcoal grate into ashcan, remove before starting.
  4. Place fire starter in charcoal grate and light.
    • Use a food-safe fire starter block or twisted paper towel/paper.
    • Place in the charcoal grate on the fire starter support bars.
    • Use caution and wear protective gloves.
    • Light with a match stick or lighter.
  5. Turn on the controller and set to the desired temperature.
    • Wait 1–2 minutes after lighting the fire starter to ensure the fire starter is fully lit.
  6. Close hopper lid and ash door.
    • This will activate the fan.
  7. Wait for the grill to reach desired set temperature.
    • Approximately 13 minutes to reach 700°F (370°C).
    • Approximately 7 minutes to reach 225°F (105°C).


If it is necessary to refill the hopper while cooking, follow the safe reloading instructions below.

• DO NOT add charcoal when the grill is in excess of 250°.

• The fan will turn off if you open the hopper lid or ash door. This reduces the chimney effect created when these doors are opened.
• Gravity fed technology works by maintaining a completely sealed hopper. When the hopper lid is opened the flame will rise from the top of the hopper like a torch. Closing the hopper lid and ash door will return the flame to the normal operating level.
• The amount of charcoal in the hopper determines how quickly the flame will rise when the hopper lid is opened.

Adding charcoal:

  1. Open hopper lid.
    • Use caution and wear protective gloves. Hopper lid will be hot.
    • Flame will rise from hopper after a short time depending on the charcoal level.
  2. Pour charcoal into hopper.
  3. Close hopper lid.


  1. Turn the controller off.
  2. Close grill lid, hopper lid, and ash door.
  3. Install heat intake and air intake slides.
    • The grill is designed to starve the charcoal of oxygen when shut down. This allows a percentage of unused charcoal to be saved for the next cook.
  4. Failure to install slides when shutting down may cause damage to the grill.


Option 1: Place wood chunks or charcoal in the ashtray to add flavor before setting the temperature. As the charcoal in the hopper burns, the hot embers will fall onto the wood/charcoal in the tray, causing it to burn at a slower rate and release more flavor into the grill.

  • NOTE: Never add more than 1⁄2 lbs at a time. Additional chunks or charcoal should not be added until any previously added has ceased generating smoke.
    Option 2: Mix wood chunks in the hopper with charcoal.
  • NOTE: Never use more than 1.5 lbs of wood chunks throughout the hopper.
