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. (Figure
13) Ventilated shields for side
trim must extend the full length
of the trim.
An unprotected mantel (“A,” Figure 2.13) cannot be more
than 9" (230 mm) deep and must have a minimum clearance
of 28" (711 mm), measured from the stove’s top plate. With
a ventilated shield, this clearance may be reduced safely to
15" (381 mm).
Unprotected top trim (B) protruding 3/4" (19 mm) or less from
the face of the fireplace must be a minimum of 25" (635 mm)
from the stove’s top surface. With a ventilated trim shield,
this clearance may not be reduced safely.
Unprotected side trim (C) that protrudes 3/4" (19 mm) or less
from the face of a fireplace must have a minimum clearance
of 22" (554 mm), measured from the stove’s top side edge.
If the trim extends more than 3/4" (19 mm), it is subject to
the requirements for wall clearance.
The charts and sample installations that follow list all the
clearances required for the various installation configurations
of this appliance.
