Frequently Asked Questions - MB20053418 Masterbuilt

How do I season the grill before first use?
Preheat the grill with a thin layer of cooking oil on the grates at 300°F for 30 minutes. This burns off manufacturing residues and creates a non-stick surface.
What type of charcoal should I use?
Use lump charcoal for higher heat or briquettes for longer, steady burns. Avoid lighter fluid; start with a chimney starter.
How do I control temperature on this charcoal grill?
Use the air dampers to regulate oxygen flow. Open them for more heat, close them to lower the temperature. Adjust gradually and monitor the built-in gauge.
How long does a full load of charcoal last?
With the dampers fully open, about 45 minutes of high heat; with dampers half open, around 2 hours at medium heat. Wind and ambient temperature affect burn time.
Can I use the grill as a smoker?
Yes, set up a two-zone fire by placing water pan under the grates on one side, and add soaked wood chips directly on the coals for smoke. Maintain lower temperatures (225-275°F).
How do I clean the cooking grates?
While grates are hot, brush them with a stainless steel grill brush. For deep cleaning, soak in soapy water and scrub with a non-abrasive pad, then rinse and dry.
How do I maintain the exterior and interior?
Clean the ash pan after every cook once cooled. Wipe the exterior with a damp cloth. Apply a light coat of vegetable oil to cast iron parts to prevent rust.
Is it safe to use on a wooden deck?
Keep the grill at least 10 feet from any structure, and place a grill pad on the deck to protect from heat and grease. Never leave hot coals unattended.
What if the temperature gauge reads incorrectly?
The gauge can be calibrated by checking it in boiling water (212°F at sea level) and adjusting with a wrench. If it doesn't move, replace it with a compatible gauge.
How do I replace the cooking grates?
Remove old grates and purchase 24-inch porcelain-coated steel grates from the Masterbuilt website. Simply lift the old grate and set the new one over the support tabs inside the bowl.

SAVE THESE INSTRUCTIONS

SMOKER OPERATION - READ & FOLLOW ALL INSTRUCTIONS CAREFULLY

GETTING STARTED

• Pre-season unit prior to first use. See PRE-SEASON INSTRUCTIONS.
• Before starting the unit, see ADDING WOOD CHIPS OR CHUNKS.

CAUTION - All surfaces are HOT and may cause burns. Use protective gloves or long, sturdy cooking tools when loading/unloading food or racks, and when adding wood chips or water.

PRE-SEASON INSTRUCTIONS

Curing your smoker will rid the unit of chemicals and oils left over by the manufacturing process allowing them to burn off.

PRE-SEASON SMOKER PRIOR TO FIRST USE.

  1. Perform soapy water test, see SOAPY WATER TEST WARNINGS AND PROCEDURES.
  2. Using a napkin or cloth, rub a light coat of cooking oil on smoking racks and inside smoker door. Make sure water pan is in place with NO WATER.
  3. Fill wood chip tray with up to 1 cup (0.24l) of wood chips or chunks and light smoker. Close door.
  4. Start smoker and let the smoker burn for about 1 hour. Make sure temperature gets up to 350°F (177°C).
  5. Allow unit to cool COMPLETELY.
  6. Reapply light coat of cooking oil on smoking racks and inside of smoker door.
  7. Restart smoker and burn for 20 minutes.

- Cure your smoker periodically to prevent excessive rust.

ADDING WOOD CHIPS OR CHUNKS

  1. You may use dry or pre-soaked wood chips or chunks in your smoker. Dry chips or chunks will burn faster and produce more intense smoke. Chips or chunks pre-soaked in water (for approximately 30 minutes) will burn slower and produce a less intense smoke.
  2. DO NOT ADD MORE THAN 1 CUP (0.24l) OF WOOD CHIPS OR CHUNKS AT A TIME. Never use wood pellets.
  3. Place additional wood chips or chunks in smoker as needed to achieve desired smoke flavor.

- Wood chips or chunks must be used in order to produce smoke and create the smoke flavor.

OPERATING INSTRUCTIONS

  1. To start smoker see IGNITION INSTRUCTIONS.
  2. With protective gloves on, place water bowl in position. Pour 1 inch of water, juice, or vinegar into water bowl. This will add flavor and moisture to food and prevent it from drying out.
    3 DO NOT cover racks with aluminum foil as this will not allow heat to circulate properly.
  3. Pre-heat smoker for 30 to 45 minutes at max temperature before loading food.
  4. Place food in the smoker, position on the center of the smoking rack.
    6 DO NOT overload smoker with food. Extra large amounts of food may trap heat, extend cooking time and cause uneven cooking. Leave space between food on racks and smoker sides to ensure proper heat circulation. If utilizing cooking pans, be sure pans do not cover more than 75% of the rack space and place pans on center of rack to ensure even cooking.
  5. For best results, rotate racks between the top and bottom positions during cooking.
  6. Adjust smoker settings, control knob and air dampers, to desired cooking temperature.

- Close all air dampers on unit to retain moisture and heat. If cooking foods such as fish or jerky, open air dampers to release moisture.

  1. If wood chips or chunks do not smoke on low setting, increase temperature to 275° . After 8 to 10 minutes or when wood chips or chunks begin to smolder, reduce temperature to desired low setting.

  2. Use caution when cooking on windy days to ensure the flame does not blow out. If you suspect or experience a flame blow out, first open the door to check the flame and follow the IGNITION INSTRUCTIONS to re-ignite the burner if needed. Adjust the burner control valve setting for a higher flame to prevent further blow outs. Never ignite smoker with the door closed.

  3. Extreme cold temperatures may extend cooking times.
  4. Once cooking is complete turn unit OFF, see IGNITION INSTRUCTIONS for turning off unit, remove the gas cylinder and then follow CLEANING and STORING INSTRUCTIONS. CLEAN AFTER EVERY USE. This will extend the life of your smoker and prevent mold and mildew.

CLEANING and STORING INSTRUCTIONS

  • ALWAYS MAKE SURE UNIT IS COOL TO THE TOUCH BEFORE CLEANING AND STORING.
  • Be sure to clean smoker after each use. Make sure the gas cylinder has been turned off and removed.
  • For rack supports, racks, water bowl, and drip pan use a mild dish detergent. Rinse and dry thoroughly.
  • For woodchip tray clean frequently to remove ash build up, residue and dust.
  • Dispose of cold ashes by placing them in aluminum foil, soaking with water and discarding in a non-combustible container.
  • For the interior, exterior and door seal of the unit simply wipe down with a damp cloth after each use to keep unit in proper working condition. Do not use a cleaning agent. Make sure to dry thoroughly.
    • After cleaning, store smoker in a covered and DRY AREA.
  • Store only when fire is completely out and all surfaces are cold.
  • When not in frequent use and using a cover, remember to check your smoker periodically to avoid possible rust and corrosion due to moisture buildup.
