Wall Shields
Wall shields should be constructed of 24 gauge or
heavier sheet metal, or another noncombustible mate-
rial such as 1/2" (13mm) insulation board or common
brick "laid on flat," with the 3¹⁄₂" (90mm) side down.
Shields must be spaced out from the combustible sur-
face 1" (25mm) on noncombustible spacers. The spac-
ers 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" (25mm) of the
shield should be open and the shield must be open at
the top.

both rear and side walls. Wall shields may meet at
corner if desired. Shielding for connector is centered
behind connector.
Parallel installation with rear wall pass-through, two
wall shields. Fig. 18: Reduced clearances for both
rear and side walls. Wall shields may meet at corner
if desired. Shielding for connector is centered behind
