The fireplace comes with a choice of decorative media options, including glowing embers and fire glass, allowing homeowners to customize the look of their fireplace to match their personal style.

Another notable characteristic of the KHLDV400 is its intuitive control system. It can be operated via a handheld remote or wall switch, providing convenience and ease of use. Homeowners can adjust the flame height and heat output with simple controls, ensuring comfort at all times. Additionally, it features a standing pilot option that enhances its reliability and safety during operation.

Durability and quality craftsmanship are hallmarks of the Monessen brand, and the KHLDV400 is no exception. The fireplace is built with high-quality materials designed to withstand the test of time. Its sleek, contemporary design features a clean-face appearance that enhances any decor, while the glass front allows for an unobstructed view of the beautiful flame display.
