Vermont Casting 1920 installation instructions Wall Shields, Approved Wall shield construction

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.
