Horizontal Wall Thimble — Use to penetrate any interior or exterior combustible or non-combustible wall. This
part is a thimble only and does not include any vent -- be sure to order enough vent to pass through the thimble.
To use this thimble, the vent must be uninsulated for a minimum distance prior to passing through a combustible wall. A minimum
distance of 18 inches is required for appliance flue gas temperatures up to 400° F. A minimum distance of 6 feet is required for
appliance flue gas temperatures of 400 - 480° F.
The opening must be 6-1/2 inches in diameter for both 3 or 4 inch diameter Saf-T Vent systems. The wall thimble is designed to
adapt to any wall thickness from 3.5” to 6” thick. If the wall is thicker than 6”, the thimble may be extended using a piece of
6” diameter snaplock or welded-seam galvanized pipe. The vent system may be terminated using any terminal Listed for use
with the appliance. The wall thimble may be painted to match the decor.
