Featuring an inventive, patent-pending design, the Blue sky Outdoor 28" Square Mammoth Smokeless Patio Fire Pit is highly efficient and smokeless, thanks to its improved airflow and oxygen-drawing capabilities. Its top-accessible lift-out ash catch makes cleaning up a breeze, while the wider bezel on top of the fire pit ensures an even more efficient smokeless burn, perfect for you and your guests to enjoy. Designed to burn firewood and/or wood pellets, this innovative fire pit generates ample heat for a memorable backyard bonfire with little to no smoke or embers. With its tongue and groove design, assembly takes only ten minutes or less, and the large burn chamber accommodates 10-12 standard length firewood logs for a longer, better burn.

How It Works:

Outside air is pulled up through the cut outs in the base of the fire pit and injected into the burn chamber. The heated air is released through the holes on the top of the burn chamber, infusing the fire with an extra boost of oxygen which improves the burn. The improved burn removes all wood particles, ash, and sparks, creating an enjoyable smokeless fire.

Yes, this fire pit does require minimal assembly of four side panels and 12 nuts and bolts. The fire pit side panels have a tongue and groove design which makes assembly easy and will only take 10 minutes or less!


This patio fire pit can burn firewood and/or wood pellets.


Wood pellets are offered at a variety of retailers: Tractor Supply, Menards, Walmart, Lowe’s, etc. Check with your local retailer to find out if they sell wood pellets. A 40 lb bag lasts roughly 6–8 hours.


It will take about 10–15 minutes for the fire pit to get hot enough for flames to get a strong blaze. The initial load will burn about 25–35 minutes before you need to add pellets.


To clean out the ashes, wait until the fire pit and any residue left in the bottom of the pit has completely cooled. With a small wisk broom or your hand, push any ash or left over pieces of wood/pellets into the center of the grate. Lift up the ash catch by the two handles on either side of the grate and pull straight up directly out of the center of the fire pit. Place the ash catch with the grate on the ground. Remove the grate and let any ashes or wood fall into the ash catch. With the grate off empty the completely cooled contents of the ash catch into a waste container for disposal or in another designated area.


This fire pit is constructed of steel which is susceptible to rust when exposed to outdoor conditions and fire. The unique design of this fire pit can generate heat in the burn chamber that can exceed 1,200 °F (650 °C). While we paint our fire pits with high temperature heat resistant paint, there are no commercially available paints suitable to meet these extremes. With use and time, these fire pits will show signs of rust. This will not impact the performance of the fire pit. The paint can be touched up with high-temperature paint, which is used on BBQ grills and other high heat appliances and can be found at most hardware stores. It is best to always keep your fire pit covered when not in use.
