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 constructed entirely of non-combustible materials (i.e.,
steel studs, concrete board, etc.). Failure to comply may
cause fire.
