Proponent: Timothy N. Seaton, B.S.C.E., Empire Masonry Heaters LLC (tseaton@timelyconstruction.com)
Revise as follows:
1002.5 Masonry heater clearance. Combustible materials shall not be placed within 36 inches (914 mm) or the distance of the allowed reduction method of from the outside surface of a masonry heater in accordance with NFPA 211, Section ~~8-7 (clearances for solid fuel-burning appliances~~) 12.6, Clearances from Solid Fuel-Burning Appliances, and the required space between the heater and combustible material shall be fully vented to permit the free flow of air around all heater surfaces.

Exceptions:

1. When the masonry heater wall thickness is at least 8 inches (203 mm) thick of solid masonry and the wall thickness of the heat exchange channels is at least 5 inches (127 mm) thick of solid masonry, combustible materials shall not be placed within 4 inches (102 mm) of the outside surface of a masonry heater. A clearance of at least 8 inches (203 mm) shall be provided between the gas-tight capping slab of the heater and a combustible ceiling.
2. Masonry heaters listed and labeled in accordance with UL 1482 may be installed in accordance with the listing specifications and the manufacturer's written instructions.

Reason: This proposal harmonizes IRC Section 1002 with the corresponding 2013 IBC Section 2112.
1) Metric conversion is incorrect; 2) NFPA 211 citation is incorrect; and 3) NFPA 211 Section 12.6 allows clearances under 36" with stipulated distance reduction strategies.
Cost Impact: The code change proposal will not increase the cost of construction.
