The Red Ember Whitehall 40 diam. Fire Pit is a low-to-the-ground fire pit that makes for cozy conversation at any time of the year. Solid gray natural stone is used to construct the piece, featuring a round fire bowl that comes with decorative rocks for a natural fill material. A stainless steel burner provides an odorless, smoke-less flame, controlled by a convenient gas-flow knob. A push-button spark-ignition makes lighting the grill a snap. Both a natural gas and a liquid propane model fire pit are available. The liquid propane option is powered by standard 20-pound tanks and comes with a sturdy weathered bronze tank hideaway table to keep the tank protected from the elements. The natural gas option comes with a conversion kit, but does not included the tank hideaway table. A licensed plumber is recommended for installation of natural gas models.
