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 (Fig. 14) or
common brick “laid on flat,” with the 3¹⁄₂" (89mm) 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. 15: 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. 16: Reduced clearances for both

rear and side walls. Wall shields may meet at corner if

desired. Shielding for connector is centered behind con-

nector. Wall pass-through must comply with codes.
Corner installation, vertical chimney connector, two

wall shields. Fig. 17: Reduced side clearances. Wall

shields MUST meet at corner.
Parallel installation with rear exit, rear wall pass-

through, rear wall shield. Fig. 18: Reduced clear-

ances for rear wall. Shielding for connector is centered

behind connector. Wall pass-through must comply with

codes.
