?Unique 3-Level Combustion? The unique structure of this fire pit will lead to 3-level combustion. As a result, the outstanding air circulating system and Oxygen-enriched fire technology ensure optimal heat with less smoke and wood. And the smokeless burning technology offers you a clean bonfire atmosphere. ?Attractive Flame Effect? In the primary combustion, the vent holes on the 2nd layer let direct air in and feeds oxygen for the burning of fuel. Then, the holes on top layer and 8 long vents feed oxygen for the unburned parts and form spiral flame, which is secondary combustion. Plus, with the bottom air vents, the airflow flows from the bottom up to the middle column, creating corn-like flame and burning off smoke particles before it gets out of the fire pit. which is tertiary combustion. ?Premium Stainless Steel? The outdoor firepit consists of 3 parts: fire ring, firebowl and body. All parts are made of premium stainless steel for long-lasting service life. Note: As the plant ash is alkaline, the fire pit will slightly rust after several time to use. And the ash tray may be slightly deformed after high-temperature burning. But these won’t affect normal use. ?Functional Protective Cover? The protective cover which resists to water and sunlight is included to offer considerate protection when the smokeless stove bonfire is not in use. Note: Never place the cover when the fire pit is in use. ?Multiple Optional Fuels? The large inner space of the fire pit bowl allows you to put more fuels for continuous burning. And there are multiple optional fuels, such as charcoal, firewood and wood pellet. Once burned, the fire pit will offer all-direction warmth, spreading heat to everyone sitting around. Suitable distance for warming: 61 cm - 305 cm.
