Fireplace and Mantel Trim Shields

A ﬁreplace installation requires special clearance

between the side of the stove and the right and left

walls, between the side of the stove and the decorative

side trim on the ﬁreplace face, and between the top of

the stove and the mantel.

Noncombustible shields

installed 1” (25 mm) away

from the combustible surface

on noncombustible spacers,

called ventilated shields,

may be used to reduce

clearances.

To protect a mantel from the

heat of a stove in a ﬁreplace

installation, use a custom-

made ventilated mantel

shield that is at least 48”

(1220 mm) long, centered

over the stove. (Fig. 14)

Ventilated shields for side

trim must extend the full length of the trim.

surfaces and objects will not overheat.

Safe Ways to Reduce Clearances

Clearance requirements are established to meet every

installation possibility, and they involve the combination

of these variables:

• When the stove pipe has no listed heat shield

mounted on it.

• When the wall has no heat shield mounted on it.

• When the wall has a heat shield mounted on it.

• When the wall and stove pipe have heat shields.

In general, the greatest clearance is required when you

place a stove and its connector near a wall with no heat

shield.

For example, when the Deﬁant is installed parallel to

the rear wall with 8” pipe and no connector shield is

used, it must be at least 35” (889 mm) from the wall

behind it and at least 23” (584 mm) from walls on either

side. These dimensions are measured from the top

edge of the stove to the combustible wall.

If the Deﬁant is installed in a corner and no shield is

used, the corners of the stove top must be at least 25”

(635 mm) from nearby walls when using 8” connector

pipe.

Clearances may be reduced only by means approved

by the regulatory authority, and in accordance with the

clearances listed in this manual. Refer to Pages 10 - 13

for approved clearance reduction speciﬁcations.

NOTE: Clearance requirements differ for 8” and 6” con-

nector pipe installation. A minimum ceiling height of 8

feet (2.4 m) is required for all installations of the Deﬁant

NC.

NOTE: Installation of the Deﬁant is not permitted in

alcoves.

Wall Shields

One way to reduce clearances is with a wall shield

constructed of 24 gauge or heavier sheet metal, or of

another noncombustible material such as 1/2” (13 mm)

insulation board such as Durock

or Wonderboard

, or

common brick “laid on ﬂat,” with the 3¹⁄₂" (90 mm) side

down.

Shields must be spaced out from the combustible

surface 1" (25 mm) on noncombustible spacers, as in

Figure 13. 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 must be open, and the shield must be open at

the top. Metal screening across the top will keep small

stray objects from being trapped behind the shield. (Fig.

13)

With 6” connections and chimneys, the shield must be

a minimum of 48" (1219 mm) tall, and must extend at

least 19" (483 mm) higher than the top of the stove,

whichever is higher. The shield behind the chimney

connector must be 30" (760 mm) wide, centered behind

the pipe; for installations that use an approved prefab-

ricated chimney to pass through the ceiling, the shield

behind the chimney connector must stop 1" (25 mm)

below the ceiling.

With 8” connections and chimneys, because of poten-

tially higher pipe temperatures, the shield must extend

the full height of the wall (up to 9’ (2.7 m)) and stop 1”

(25 mm) below the ceiling.
