Structural Proximity And Safety Usage



Diagram showing safe distance between unit and other objects

Let’s Get Started

  • This is a slow smoker so allow sufficient time for cooking. The smoker is for OUTDOOR USE ONLY.
  • “Pre-season” smoker prior to first use. See page 23.
  • Pre-heat smoker for 30 to 45 minutes at max temperature before loading food.
  • DO NOT cover racks with aluminum foil as this will not allow heat to circulate properly.
  • 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, place pans on the center of rack to ensure even cooking. Never use glass, plastic or ceramic cookware in unit. Please see manual for more detail.
  • Store smoker in a dry area after use.
  • Extreme cold temperatures may extend cooking times.
  • CLEAN AFTER EVERY USE. This will extend the life of your smoker and prevent mold and mildew.

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


How To Clean And Store Smoker

Be sure to clean the smoker after each use. Make sure your smoker is unplugged and completely cool.

For rack supports, racks, water bowl and drip pan use a mild dish detergent. Rinse and dry thoroughly.

For wood chip tray and wood chip loader, 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, glass inside-door, and exterior of smoker, simply wipe down with a damp cloth. Do not use a cleaning agent.

Make sure to dry thoroughly.

After cleaning, store smoker in a covered and dry area.

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.

Pre-season Instructions


Some smoke may appear during this time, this is normal.

  1. Make sure water pan is in place with NO WATER.
  2. Set temperature to 275°F (135°C) and run unit for 3 hours.
  3. To complete pre-seasoning, during last 45 minutes, add ½ cup of wood chips in wood chip loader and unload wood chips into the wood chip tray. This amount is equal to the contents of a filled wood chip loader.
  4. Shut down and allow to cool.

NOTE: Never add more than ½ cup (1 filled chip loader) at a time. Additional chips should not be added until any previously added chips have ceased generating smoke.

How To Use Wood Chip Loader

How To Use Wood Chip Loader:

  • Before starting unit, place ½ cup of wood chips in chip loader.
  • Never use more than ½ cup of wood chips at a time. Never use wood chunks or wood pellets.
  • Insert wood chip loader into smoker. Wood chips should be level with top rim of wood chip loader.
  • Turn handle clockwise in direction of arrow mark on smoker to unload wood. Wood will drop into wood chip tray. Turn handle counterclockwise, to upright position, and leave wood chip loader in place.
  • Check wood chip tray periodically to see if wood has burned down by removing wood chip loader and looking into smoker through hole. Add more chips as needed.
  • Wood chip loader must be pulled out completely from smoker when checking wood chip level.

Adding More Wood During Smoking Process:

  • Pull wood chip loader from smoker.
  • Place wood chips in wood chip loader and insert into smoker.
  • Turn handle clockwise in direction of arrow mark on smoker to unload wood. Wood will drop into wood chip tray.
  • Temperature may spike briefly after wood is added. It will stabilize after a short time. Do not adjust temperature setting.

Inserting the thermometerCaution:

  • Keep smoker door closed when adding wood chips.
  • Wood chip loader will be HOT even if handle is not.
  • Never use wood pellets or wood chunks.


When the door has opened a flare-up may occur. Should wood chips flare up, immediately close door and vent, wait for wood chips to burn down, then open door again. Do not spray with water.

How To Use The Water Bowl

How to use water bowl:

  • Wait until smoker comes up to desired temperature.
  • Fill water bowl to fill line with water or liquids like apple or pineapple juice instead of water.
  • You can also add slices of fruit, onions or fresh dried herbs into the water to blend different subtle flavors into your smoked food.

Tip: For chicken or other foods high in moisture, little or no liquid is needed.

Important Facts About Using Smoker

  • Maximum temperature setting is 275°F (135°C).
  • Do NOT move unit across uneven surfaces.
  • Wood chip loader and wood chip tray MUST be in place when using smoker. This minimizes the chance of wood flare ups.
  • Wood chips must be used in order to produce smoke and create the smoke flavor.
  • Check grease tray often during cooking. Empty grease tray before it gets full. Grease tray may need to be emptied periodically during cooking.
  • Do not open smoker door unless necessary. Opening smoker door causes heat to escape and may cause wood to flare up. Closing the door will re-stabilize the temperature and stop flare up.
  • Do not leave old wood ashes in the wood chip tray. Once ashes are cold, empty tray. Tray should be cleaned out prior to, and after each use to prevent ash buildup.
  • This is a smoker. There will be a lot of smoke produced when using wood chips. Smoke will escape through seams and turn the inside of smoker black. This is normal. To minimize smoke loss around door, door latch can be adjusted to further tighten door seal against body.
  • Opening smoker door during cooking process may extend cooking time due to heat loss.
  • When outside temperature is cooler than 65°F (18°C) and/or altitude is above 3,500 feet (1067m), additional cooking time may be required. To insure that meat is completely cooked use a meat thermometer to test internal temperature.
  • To adjust door latch, loosen hex nut on door latch. Turn hook clockwise to tighten as shown. Secure hex nut firmly against door latch. (see diagram)
