Maximize the heat in your room with a GRUF36C-F vent free firebox. It offers a radiant, clean face and includes Cottage Clay firebrick liner. It offers a beautiful 34" wide viewing area. With a log set (sold separately) of your choice, you will warm up quickly. No chimney is required for a vent free fireplace and since it is also a zero clearance firebox, it can be installed flush against virtually any surface including drywall or wood. Plus this also gives you the flexibility of installing on an interior or exterior wall!
With a vent free firebox, fresh air is drawn in at the bottom of the firebox, and warmed air is expelled into the room from the top. The GRUF firebox features an angled top design to help direct the warm air out for maximum efficiency. A blower (BLOTMC) can be added to help circulate the warm air.
The GRUF firebox can accept most 24" and 30" vent free log sets and burners (sold separately). With zero clearance, the firebox can be installed flush against any surface like drywall or wood.

An optional outside air kit is also available for vent free fireboxes. The AK4 introduces fresh, outside air into the firebox. An outside air kit is recommended as an accessory when installing a vent free appliance into newer, more air tight construction for an adequate supply of fresh air. Some local building codes may require an outside air kit.
