Abstract: A combination ash collector cover and combustion enhancer for a fireplace which serves to deliver outside air to the combustion chamber of the fireplace via the ash collector opening. In the preferred embodiment, an outside blower draws in air which is directed through the pressurized ash collector through a unique cover plate having integrally formed air jets extending upwardly therefrom for directing the air to the combustion zone. More particularly, the combination cover-exhaust fits over standard ash collector openings and includes a pair of angularly disposed air pipes centered about a vertical central air pipe about which a brace and poker handle are formed. In the off-season, the combination cover plate and duct assembly may be inverted in the ash collector opening to conceal the exhaust jets therewithin.
