Do I need an air mixer for my fire pit?

You only need an air mixer for your fire pit if you are using propane. If you're using natural gas, an air mixer is unnecessary.

The reason for this is that propane, more dense than air, creates a byproduct of black soot when burned at the appropriate temperature to create the yellow flames we all love to see in outdoor fire pits. When propane gas is used with an air mixer, there is some additional combustion air added to the fuel at its burning point, which greatly reduces the issue of sooting. If you're buying a propane fueled fire ring, fire ring kit, or deluxe fire pit kit from Gas Products Company, an orifice and air mixer is added to your purchase automatically. That's just our way of helping to make your life easier.
