Up To Date 45++ Sealed Combustion Fireplace
Up To Date 45++ Sealed Combustion Fireplace. Early state select sealed combustion water heater with a partially blocked air intake; When the fire is off, we feel an obvious draft of the cold air from outside coming into the living room and the floor in this is our gas fireplace at our new construction home. With a sealed venting system and firebox, direct vent fireplaces won't draw air from inside the home for combustion, nor will combustion byproducts, like carbon monoxide, be able to enter back into.
