The following examples of wall shield construction illustrate
common designs used to safely achieve reduced clearances
to combustible wall materials.
Parallel installation, vertical chimney connector, two
wall shields.
Figure 4.5: 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.
Figure 4.6: 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.
Figure 4.7: Reduced side clearances. Wall shields
MUST meet at corner.
Wall Shields:
Wall shields should be constructed of 24 gauge or heavier
sheet metal, or another noncombustible material such as 1/2”
(13 mm) insulation board or common brick “laid on flat,” with
the 3
-1/2
" (90mm) 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.
