FireRock vent free fireplace modelVent-Free Indoor Fireplace

A Vent-Free fireplace provides great atmosphere to any home, with less hassle. This gas burning fireplace does not require any chimney or ventilation, so it weighs significantly less than comparable wood burning fireplaces - while still providing a true masonry look. Due to the no chimney requirement, the Vent-Free produces less heat loss and is one of our most versatile models (can be installed in nearly any space, but requires special codes for bedrooms). The FireRock Vent Free Gas Fireplace has a zero inch clearance, so the firebox can be installed directly on a wooden or other combustible floor, making it ideal for remodeling projects.

The Vent-Free Lite gas fireplace is a lightweight option of our indoor Vent-Free model that also provides a striaght back wall configuration. A shallower firebox allows for lighter components and easier masonic work.
