Sit back, relax, and keep warm next to this 35" Faux Slate Firepit. This sleek, low profile firepit is constructed of durable, fire retardant magnesium oxide with a stainless steel 50,000 BTU burner. Perfect for your patio, or to take on the go for your next campfire, this firepit uses a standard 20 lb propane tank (which must be placed outside the firepit). Natural red lava rocks radiate heat, and accent the the modern greenish gray stone look. The flame is fully adjustable, and quick to light with the push of a button.
