wall Shields
Wall shields should be constructed of 24 gauge or
heavier sheet metal, or another noncombustible mate-
rial such as 1/2" (13 mm) insulation board (Fig. 14) or
common brick "laid on flat," with the 3¹⁄₂" (89 mm) side
down.
Shields must be spaced out from the combustible
surface 1" (25 mm) on noncombustible spacers. The
spacers should not be directly behind the stove or
chimney connector.
Air must be able to flow between the wall and the
shield. At least 50% of the bottom 1" (25 mm) of the
shield should be open and the shield must be open at
the top.
