Natural gas is often preferred for permanent installations where a gas line is already available, as it is safer, burns cleaner, and eliminates the need to refill tanks. Propane offers more flexibility since it comes in portable tanks, making it suitable for a wider range of locations. If using a standard 20 lb portable propane tank, expect a maximum output of around 100,000 BTUs and roughly 4–10 hours of burn time depending on your heat setting.
Cooking over a gas fire pit is not recommended — grease and food drippings can clog the small holes in the burner, and the yellow decorative flames produce soot and carbon that can contaminate your food. Most gas fire pits are certified as decorative appliances, not cooking appliances, and CSA regulations specifically discourage cooking over them. If you want to cook outdoors, a dedicated fire pit grill designed for that purpose is a better option.
The heat output of a gas fire pit is measured in BTUs (British Thermal Units), with most residential models ranging from 50,000 to 125,000 BTU, though some large kits can reach up to 400,000 BTU. As a general reference, 50,000 BTU is roughly equivalent to a comfortable medium-sized campfire. How much warmth you actually feel will also depend on wind conditions and how close you are sitting to the pit, since the heat rises from the flame rather than radiating from hot coals like a wood fire.
In most cases, yes — gas fire pits are less regulated than wood-burning pits because their heat output is capped and all the heat rises upward, posing less risk of damage to deck materials below. It is generally recommended to maintain about 10 inches of clearance from the deck surface to the bottom of the burner. You should always verify that your specific fire pit is rated for deck use and check the manufacturer's manual for any clearance requirements around surrounding structures.
Structural components made from stainless steel or brass can last a very long time or even carry lifetime warranties, while working parts like electronic igniters and valves are typically warrantied for one to three years but can last longer with proper care. It is always recommended to cover your fire pit when not in use to protect metal components from water damage, rust, and debris buildup. Routine maintenance includes regularly checking gas connections for leaks, cleaning the burner ports to prevent blockages, and removing any debris from the fire media after each use.
