How Far Should I Build a Gas Firepit From a Deck?

Fire Pit

• Gas fire pits come in a variety of forms, from small portable units that can be placed on a deck to large pits that put out enough heat to rival a campfire. Gas fire pits can be built into the ground or built to stand taller, at the height of a bar-style table. Ceramic logs or stones placed within the fire pit help distribute heat and add to the decorative nature of them. Fire pits are intended to be gathering places outside, where the flames’ heat and beauty add to conversations with company.

Distance

• If you want to install an in-ground gas fire pit in your back yard, for safety, you want at least 3 feet between the outer edges of the fire pit’s container and your deck. This reduces the fire danger. Because people usually stand or sit around a fire pit to enjoy it, take into account the fact that someone will probably sit between the fire pit and the deck. Add another few feet to the distance so she isn’t forced uncomfortably up against the deck. Leaving 10 or 12 feet between the pit edge and the deck gives you more seating options.

Other Safety Needs

• In addition to leaving clearance space on the sides of the pit, also make sure there is plenty of clearance above the pit. Don’t have overhanging branches closer than 7 feet to the top of the pit structure. Have a licensed plumber run the gas lines to the fire pit. You will need to have an emergency shut-off valve for the gas lines. It can be installed near the stove or closer to your house. You could need to put down gravel to improve drainage around the fire pit.

Considerations

• Before beginning any work building your gas fire pit, consult with a local building inspector. Some localities forbid the use of wood-burning fire pits out of concern for pollution; she can tell you which types are permitted in your area. She can also review your plans and let you know if your municipality requires two shut-off valves on gas fire pit and fire places. If the designer of your fire pit recommends greater distance between the pit and structures like decks, follow his suggestions.
