B-Vent Indoor FireplaceOur B-Vent fireplace is an efficient model that is primarily meant to be used in bedrooms (due to the safety concerns with carbon monoxide emissons). The B-Vent model offers an automated safety shut off valve - ensuring your fire does not burn too long or too hot. B-Vent fireplaces must be installed through the home and terminate above the roofline. They use room air for combustion, and all combustion fumes are vented outside your home. This model is a gas-only fireplace option which requires a special double-walled 10" metal chimney pipe (purchased separately). The customized chimney pipe allows for higher reflection similar to a dryer, and stays hotter to draw gases out more quickly. The B-Vent fireplace also requires an accessory kit which FireRock stocks, and is our only model that we stock gas logs for. This masonry fireplace model can be installed directly onto a combustible subfloor.
