How To Measure a Factory Built Fireplace
Print out the form to help you measure your prefab factory built fireplace. Prefab fireplaces have masonry panels inside that have a brick pattern and the flue pipe is a round metal pipe. There is usually a data tag riveted inside the fireplace somewhere, look for it above the masonry panels or behind the pull screens, make a note of the manufacturer and the model number of the fireplace.
Take photos of the fireplace, make sure the doors, if present, are open when taking photos. Take a photo outside of the chimney.
