NO!

There are two complementary approaches to operating any kind of fire pit on a wood/composite deck — screening the fire pit and protecting the deck. Because of fire's unpredictable nature, savvy homeowners often choose to combine these strategies.

Protect the Deck

Before installing a fire pit on a wood/composite deck, ensure the deck can hold its weight, as well as a fire pad or fireproof surface. Depending on the size and type of fire pit, homeowners may need to seek a contractor or structural engineer's advice.

A fireproof zone should surround the fire pit, made of stone patio tile, ceramic tile, stone pavers, or gravel. Homeowners can create a fire pad by laying tile on fiber-cement siding. A fireproof fire pad that can withstand temperatures up to 1,400 degrees Fahrenheit is a good alternative. This safe zone should extend a minimum of 24 inches away from the fire source in every direction, including away from railings, furnishings, decor, and plants.

Spark Screen

After lighting the fire, be sure to place a spark screen over the fire pit. If a wood-burning fire pit does not come with one, measure the unit and purchase a screen. Spark screens keep the embers from scattering into the surrounding area, while still allowing the warmth and light of the fire to emanate.

Safety Measures

Regardless of the options used to contain the flames and stray embers, especially from a wood fire, keep some safety measures close by, including heavy gloves, a bucket of water, and a full fire extinguisher. An unpressurized hose extinguishes flames without pushing embers onto the deck.

Remove tripping hazards near the fire pit, keep the fire unlit on windy days, and always keep an eye on the fire. When the evening is done, let a wood fire burn out and cover with sand or water to cool it safely.
