Heat & Glo Cosmo 35 Inch Natural Gas Insert With IntelliFire Touch Ignition System – Black (COSMO-I35-IFT)

The Heat & Glo Cosmo 35-Inch Natural Gas Fireplace Insert offers a contemporary solution for updating an existing wood-burning fireplace. Designed for installation inside a suitable masonry or approved factory-built fireplace, it combines a clean, modern silhouette with a visually striking flame presentation. The fluted black glass interior adds depth behind the flames, creating an attractive focal point in modern and transitional living spaces.

Equipped with IntelliFire Touch electronic ignition, the Cosmo I35 provides convenient operation with its included RC400 touchscreen remote. The natural gas burner delivers an input range of 21,000–30,000 BTU per hour, while the included GFK-160A variable-speed fan helps circulate warm air into the room. Ceramic viewing glass and the integrated direct-vent system support controlled combustion, with exhaust routed outdoors through an approved chimney-liner installation.

Homeowners can personalize the appearance with optional Clear, Amber, Cobalt Blue, Ebony, Iced Fog or Scarlet glass media, ceramic River Rock stones, or a compatible Driftwood log set. Decorative front styles include Firescreen, Halston Arch, Iron Age and Inside Fit, with compatible finishes including Black, Gun Metal and New Bronze. Coordinating metal surrounds are available in multiple sizes to cover gaps between the insert and the existing fireplace opening. The decorative front, surround and selected firebed media are sold separately and must be included when completing the installation. The Cosmo is approved for supplemental room heating or decorative use, not as a primary heat source.
