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.
The following examples of wall shield construction illus-
trate common designs used to safely achieve reduced
clearances to combustible wall materials.
Parallel installation, vertical chimney connector,
two wall shields. Fig. 17: Reduced clearances for
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
connector. Wall pass-through must comply with codes.
Corner installation, vertical chimney connector, two
wall shields. Fig. 19: Reduced side clearances. Wall
shields MUST meet at corner. ST248
