Can I cook on my gas fire pit?

Cooking on your gas fire pit is not recommended. The grease or drippings from your food will clog the burner and give your media a dirty appearance. Fire pits also burn a bright yellow flame for appearance and yellow flames produce soot and smoke. They don’t soot up your media too much because the bottom, blue-er portion of the flame is what’s touching them. The tops of the flames, though, the parts that would be cooking your food, would produce a heavy sooty covering on what you’re cooking.

If you want to cook on a fire pit, we recommend looking into a fire pit grill which use wood instead of gas. Only cook over your wood fire pit if you are using a hardwood, as other woods can be toxic.

What is the best way to choose my burner ring size?

We recommend that you get a fire pit ring that is 12" smaller than the inside diameter of your fire pit. For instance, if your inside diameter is 42", you will need a 30" fire pit ring. This will allow for a safe distance from the edge of the fire pit, as well as help to maintain an aesthetically pleasing look.

When should I have a pan under the burner?

For natural gas, having a pan under the burner isn't necessary but it is recommended. A pan keeps excessive debris from potentially clogging the burner nozzles, adds extra support for the burner and it also makes it easy to access the gas line for inspection. Another benefit is that it cuts down the amount of medium you have to buy because the pan supports the gas line which means that you won't have the fill the bottom of the pit with gravel to hold the pipe up.

For propane, a burner pan is necessary because an air mixer is required to ensure a clean and safe burn. A pan will provide adequate space for the air mixer to function.

How big does my gas line need to be?

The size of the gas line depends on the gas pressure, size of the fire pit, length of run, and max btu/h rating of the burner. The more gas the burner puts out, the bigger your line needs to be.

If you are unsure what size gas line you should use, contact a professional contractor to assist you.

Why does my gas fire pit make a whistling sound?

Usually that annoying whistling sound is caused by the flex line. Make sure that it is routed where there are no major bends or kinks in the line. Whistle Free Flex Lines are also preferred. If you have determined that your flex line isn't the issue, the next thing to look at would be the gas supply pressure. We recommend that you call in a professional to check the pressure and make necessary adjustments.

Do you install the burner ring facing up or down?

We suggest that you install it with the holes pointing upward so that you will get a larger flame more effectively. Another benefit is that you will get more heat pointing the holes upward. When it is pointed down, the heat flows into the base of the fire pit, which could damage the fire pit over time.
