Phoenix Model 8612 Clearances For Masonry Fireplace Installations INSTALLATION INTO A MASONRY FIREPLACE BUILT TO UBC CHAPTER 37. Do not remove brick from the fireplace to accommodate the stove. Connect the flue outlet directly to the chimney flue. The chimney flue must have a minimum inside diameter of 6” (152 mm) or a maximum measurement of 8” x 8” (203 mm x 203 mm) square. If the chimney flue is larger than 8” x 8”, reline it to meet the required flue size A: Side wall to stove: 20” (51 cm) B: Side trim to stove: 15” (38 cm) C: Top trim to stove: 22” (56 cm) D: Mantel to stove:
27” (69 cm) Chimney Connector (Stovepipe) Clearances The National Fire Protection Agency provides recommended minimum clearances for chimney connectors to combustibles such as walls, ceilings and floors. Once the stove is installed at safe distances from combustible surfaces, it is also important to maintain proper connector clearances for the reminder of the installation. For example, horizontal runs of stovepipe must maintain NFPA recommended clearances from the ceiling. However, other minimum recommendations are exceeded when following the required clearances for the stove to combustible materials, because our stove combustibles clearances take precedence over connector clearances.
For walls and ceilings, the NFPA recommendation for single wall pipe is 18” (457 mm) and for close clearance pipe, it is 5” (127 mm). For flooring, the floor protector’s minimum area must be under the chimney connector and 2” (50 mm) beyond each side. 1. 24 gauge, single wall pipe to wall = 18” (457 mm). 2. Close clearance pipe to wall = 5” (127 mm). Hearthstone Quality Home Heating Products, Inc ® www.hearthstonestoves.com 12
