D. Vertical Termination Requirements
• Vertical vent terminations are NOT permitted on the
LEGACY product. If a vertical vented installation is
necessary, a chase must be constructed, that maintains
minimum clearances to combustible materials, to allow
the horizontal termination cap to be used.
Note
: Proper termination clearances to windows,
doors, electrical service, etc. must be maintained as
shown in Section 4 of this manual.
Figure 7.8
When properly installed the damper collar must overlap
into the wall shield vent pipe. A minimum of 1-1/2 in. (38
mm) overlap is required for both the damper collar and
heat shields. The damper collar and heat shields are
designed for use on finished wall thicknesses ranging
from 4 in. minimum to 7 in. maximum. If the wall thickness
is greater than 7 in., a damper collar extension and
extended heat shield must be used.
WARNING! Risk of Fire! To prevent overheating and
fire, heat shields must extend through the entire wall
thickness.
• DO NOT remove the heat shields attached to the wall
shield or the termination cap (shown in Figure 7.8).
• Heat shields must overlap 1-1/2 in. (38 mm) minimum.
