B. Clearances To Combustibles
Use the chart below together with the diagrams in Figure 4.3 to determine the required clearance for your particular installation.
Stove clearances are measured from the top plate to the combustible surface.
Chimney connector clearances are measured from the connector surface and take into account flue collar offset.

Front Clearance to Combustibles
All Installations:
48" (1219 mm)
** A distance of 48" must be maintained between the stove and movable combustible items such as drying clothes, furniture, fire
-
wood, etc.
1
When a rear heat shield is installed on a top exit stove, the shield insert must be attached to the shield so the area behind the flue
collar on the stove is protected.
2
Chimney connector heat shields must extend exactly 24" (610 mm) above the top of the stove. No shielding can be used on the
connector above 24" (610 mm). The unshielded chimney connector above the 24" (610 mm) point must be 13" (330 mm) from an
unprotected wall.
3
In top exit installations, this clearance requires the use of the rear stove heat shield with the flue collar cover plate installed.
