2013 IRC Code Change Proposal RB456


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.


      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.



    Public Hearing: Committee: D - refers to wrong 211 section. Invited to amend at public hearing.

    Assembly: ASF AMF DF
