Perfect Guide Before Build Chimney Chase

Build chase of fireplace just like any other wall structure by placing its uprights between plates and top plates to create a large box. A header – essentially, a 2 by 4 transom – on chase front creates an opening for fireplace or insert. Sketch dimensions of chase if you do not have an architectural drawing to follow. They allow at least minimum specified by fireplace manufacturer between chase and fireplace. Your chase is likely to be at least 6 feet wide, allowing a mantel, stone front and gas line access, 2 to 3 feet deep, based on manufacturer’s specifications.
Mark measures dimensions on ceiling of wall. Drop a plumb bob from top corners to floor and mark these points. Complement chalk lines on ceiling and floor to mark chase dimensions. Saw 2-by-4 wood to serve as cover and plates for front and sides of chase. Put on floor. Mark stud locations every 16 to 24 inches. Stack two 2 by 4 blocks on floor and measure up to ceiling chalk line to get to your pole measurements: blocks represent thickness of unique and top plates.
