The invention relates to fireplace structures, particularly of the open hearth type, wherein a combustible fuel is subjected to combustion with oxidizing air generally drawn from the space into which the structure opens. The present invention additionally includes an ambient air inlet for drawing air from without the room into which the structure opens, allowing the fireplace to be operated with a telescoping hood in either a raised or lowered position. The present invention further includes a mechanism for raising and lowering a telescoping hood, and a further ash removal mechanism operable to remove products of combustion from the bottom on the fireplace grill to an external point of deposit. |
