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.

Dependent claims

In combination with a fireplace having a hearth, a combustion chamber position above said hearth, an ash collector positioned below said hearth, and an opening formed in said hearth leading to said ash collector, the improvement which comprises a combination ash collector cover and combustion enhancer, which comprises:

cover means comprising a substantially planar plate removably positioned over said ash collector opening of said fireplace;
pipe means comprising at least one air pipe extending outwardly from said plate for placing said combustion chamber of said fireplace in fluid communication with said ash collector, said at least one air pipe forming an air channel one end of which in use terminates below said combustion chamber but substantially above the plane of said plate for permitting ashes to accumulate on said plate without clogging said pipe;
and
means for pressurizing said ash collector for causing air to flow therefrom through said pipe means into said combustion chamber so as to enhance combustion therein.
