Clearances With Double Wall Chimney
Connectors And Rear Stove Heat Shields

clearance is 12" (300 mm).

Connectors, Connector Shields And Rear

Use of both stove and chimney connector heat shields,
on single-wall connectors, in top-exiting installations
reduces the required clearance. (Fig. 10)

Protected Walls
A properly constructed wall shield may be used to
change an unprotected wall to a protected wall, allow-
ing the clearances given in the right half of the Clear-
ance Chart.
Wall shields should be
constructed of 24 gauge
or heavier sheetmetal,
1/2” noncombustible insu-
lation board, or common
brick laid on flat (3¹⁄₂" side
down). Shields must be
spaced out from the com-
bustible wall or ceiling 1"
on noncombustible spac-
ers. The spacers should
not be directly behind the
stove or chimney connec-
tor.
Air must be able to flow
between the wall and the
shield. At least one-half
(50%) of the bottom 1"
of the shield should be
open and the shield must
stop 1" from the ceiling.
Protect the top opening
with metal screening to
prevent objects from fall-
ing behind the shield.
Rear wall shields must extend 18" above the top of the
stove or to within 1" of the ceiling, must be centered
behind the stove, and must be a minimum of 48" (1220
mm) wide by 48" high.
Side wall shields must be 48" (1220 mm) wide by 44"
high, and must extend 15" (380 mm) beyond the front
of the stove as measured from a point on the wall that
is on the same plane as the door glass.
