Tools Needed:

  • Steel Tape Measure
  • Pencil
  • Notepa
Instructions:
  1. Start By measuring the depth of the top of the firebox from the front of the firebox to the front of the lintel (D1). Record this measurement on your notepad. (Example: D1 = 3.5")
  2. Measure the height of your firebox opening in the center of the firebox from the firebox floor / hearth to the bottom of the lintel (H3). Record this measurement on your notepad.

 

Notes:

  • Make sure to record your measurments in inches.
  • Record your measurements in decimal format to the nearest 1/16 inch.
  • The lintel is a piece of steel that holds up the top row of bricks in the fireplace opening. It is used in the construction of the masonry fireplace to hold the bricks firmly in place until the mortar dries and often left in place to provide support.
  • If your fireplace does not have a lintel, mark "n/a" or "none" in the measurement field.
