A: Hi Bob. Thank you for your question. The specifications do not accurately state the depth that the insert is into the firepit. It appears that the insert is about 8-10 inches in depth. Please let us know if we can be of further assistance. Rick_HD_OC
A: We didn't use a block kit. Just bought individual blocks and built it around the fire pit insert. It's awesome. We've had it for 4-5 years and it's held up great.
A: 23"x23" are the inside dimensions. Thank you for your inquiry!
A: 24 inches
A: The rough opening should be no less than 23”x23” and no greater than 27”x27”. 24”x24” would be about perfect.
A: It should work, outside diameter is 27", inside is 22 1/2".
