The Napoleon Fiberglow™ VF30 Vent Free Gas Log Set doesn’t need a chimney or wood. The Fiberglow™ VF30 uses the air currents in your home to vent and circulate the warmth that it generates. There is no chopping and carrying in wood or lighting and hoping it catches. The simple to use controls allow you to sit back and relax to a roaring fire with no work. The Napoleon Fiberglow™ Vent Free Logs are a great addition to a home where fireplaces were not an option before, and ideal for an inexpensive installation or where an optional fireplace was never installed. NOTE: Vent Free Products are not approved in Canada and some States. Please check your local codes regarding vent free products.
