It would appear that it is 41-3/4" from the wood floor in front of the hearth to the top edge of the fireplace opening and 52"from the wood floor to the top of the brick opening. The brick opening is a little over 43" wide and 35" tall. The Heatilator opening is 34" wide at the front and 20" tall in the front. The firebox depth is 16 1/2" fron the heatilator doors to the rear. The back width of the firebox is about 20". The opening of the heatilator is about 4 3/4" above the hearth. The width of the hearth is 122" The hearth extends 24" from the front of the Heatilator to the front edge of the rock hearth The top of the hearth front is 17" to the wood floor. 8" damper removed and a 6" SS liner installed to the existing insert.
