Mountain-inspired, Give In To The Joys Of Leisure With This Warm, Inviting Gas Fire Pit

We all enjoy the warmth and ambiance of a fire, but we don't always have the perfect space to build one. Wood-burning fire pits are also difficult to deal with- ashes and smoke are some of the many hazards they pose.

Say goodbye to messy fireside experiences and hello to our modern linear gas fire pit. The Mt. St. Helens is built with Glass Fiber Reinforced Concrete, ensuring it's stronger than any regular concrete fire pit and completely rustproof to last for many years. What's more, it comes in 7 colors to match any patio decor you may have.

Set at the perfect height of 16", it's less intrusive between conversations, which is perfect for having casual social gatherings on your patio. It ensures easy operation with a Match Lit Ignition, letting you effortlessly light and adjust the flames. But most of all, it's made in the USA, guaranteeing it will last for many years. 

If you're looking for a fire pit idea, this linear fire pit is an awesome one. You'll love how it creates a space for people to sit by a fire and bask in luxurious comfort.

Lava is a porous rock with lots of tiny holes, like a sponge it absorbs moisture from the air. Steam forms when water gets inside and is heated up. This may cause it to expand and pop. You can prevent this by covering your fire pit from the rain or by drying out any wet rocks before lighting. It is a good idea to let the fire burn for a few minutes to clear any moisture before gathering closely around the fire. Glass media has the same issue but to a lesser extent as it is less porous.

Avoid overfilling the burn area with decorative media to prevent small pops from occurring.
