ABSTRACT:
A pair of open-sided and inverted channel members of substantially the same cross-sectional shape are disposed in laterally nested relation with the exterior transverse cross-sectional area of the inner channel member being substantially the same as the interior cross-sectional area of the outer channel member. The channel members are freely longitudinally shiftable relative to each other between relatively lengthwise extended and retracted positions and adjustable damper structure is carried by opposite ends of the channel members for adjustably throttling the discharge of combustion air therefrom when the channel members are disposed upon and supported from the floor portion of a fireplace upwardly through which a combustion air inlet opens. An associated fireplace grate for supporting wood to be burned may be positioned over the air diverter and the length of the latter as well as the adjustable damper structure may be used to divert the desired quantities of combustion air toward opposite side portions of the solid fuel to be burned upon the fireplace grate.
