B. Clearances
WARNING! Risk of Fire!
You must comply with all minimum air space clearances to combustibles as specified in Figure 3.2. DO NOT pack required
air spaces with insulation or other materials. Framing or finishing material used on the front of, or in front of, the fireplace
closer than the minimums listed must be constucted entirely of non-combustible materials (i.e., steel studs, concrete board,
etc.). Failure to comply may cause fire.
