IMPORTANT NOTES FOR USING THE APPLIANCE
Temperature setting is limited at 275°F (135°C) maximum.
Wood chip tray MUST be located properly during operation. This can reduce and prevent
wood chip flare-ups.
Appropriate wood chips must be selected in order to produce smoke and create smoke
flavor.
Soak wood chips in water for at least 30 minutes before using in order to generate more
smoke and flavor.
Clean up and empty the wood chip tray prior to smoke every time. Do not leave any old wood
ashes in the wood chip tray. Once the ashes are cold, empty the tray.
Clean up and empty the drip trip before smoking.
Do not open the door unless necessary. Opening the door can cause heat loss and may
cause wood chip to flare up. Closing the door can stabilize the inner temperature and stop to
flare up.
Opening the door during smoking can extend cooking time due to heat loss.
If outside temperature is lower than 65°F (18°C) and/or altitude is higher than 3,500 feet
(1067m), additional cooking time may be needed. Use a meat thermometer or meat probe to
measure the internal temperature to ensure the meat is completely cooked.
Tempered glass is used for door and will not break under normal operation.
Do NOT move unit across uneven surfaces.
Rear handle is NOT used for lifting.
There will be plenty of smoke produced when using wood chips. Excess smoke will leak from
door seams and make the inner side black. It is normal. To minimize the smoke loss from the
door, you can adjust the door latch in order to tighten the door seams against body surface.
To adjust door/drawer latch, loose the hexagonal nut on door/drawer latch then turn the hook
clockwise to tighten. Secure hexagonal nut firmly against door/drawer latch.
