Reduced Clearances - Osburn 2200 Owner's Manual

1.2.1 REDUCED CLEARANCES

You may decrease the clearances by installing heat radiation shields between the walls or the
ceiling and the stove. These heat radiation shields must be installed permanently, and can
include sheet metal, a rigid non-combustible sheet or a masonry wall.
Clearances of not less than 1" (25 mm) and not more than 3" (76 mm) between the bottom of the
shield and the floor and not less than 3" (76 mm) between the top of the shield and the ceiling
must be respected to allow vertical air circulation behind the shield. The shield must extend 20"
(500 mm) above the stove top and 18" (450mm) to each side of the stove (see Graphic 1).
Following the installation of such a heat radiation shield, the clearances mentioned on the stove
certification plate may be reduced as stated in the following table.
TYPE OF PROTECTION
Sheet metal, a minimum of 0,024" (0,61mm) spaced out
at least 1" (25mm) by non-combustible spacers (see
graphic 2).
Ceramic tiles, or an equivalent non-combustible material
on fire-proof supports spaced out at least 1" (25 mm) by
non-combustible spacers (see graphic 3).
Ceramic tiles, or an equivalent non-combustible material
on fire-proof supports with a minimum of 0,024" (0,61
mm) sheet metal backing spaced out at least 1" (25 mm)
by non-combustible spacers (see graphic 4)
Brick spaced out at least 1" (25 mm) by non-combustible
spacers (see graphic 5)
Brick with a minimum of 0,024" (0,61 mm) sheet metal
backing spaced out at least 1" (25 mm) by non-
combustible spacers (see graphic 6).
