 Seems big to me
I looked at the PDF for the casa 100 instalation. It said the hearth slab was 58 inches wide by 66 inches deep. It said the foundation slab should be at least 4 inches bigger than the hearth slab to support whatever trim material you are planning to use. That would be 62" x 70" Obviously if you wanted a thicker decorative covering, like 4" wide bricks, you would want a bigger slab than that.
Good luck. |
