Vent Configuration: Vertical Termination
Vent configurations 20’ or above (from the base of the fireplace) use 6-5/8” dia. vent. Connect a 8” to
6-5/8” reducer directly to the fireplace (98900165).
NOTE
: The included thimble assembly is not required and may be discarded.
The termination must fall within the shaded area shown in the chart. Use the indicated restrictor positions.
Up to four elbows (30°, 45°, 60° or 90°) may be used. Only one horizontal elbow may be used.
This is considered a
horizontal elbow (it doesn’t
matter whether it turns right
or left). It may be a 30°, 45°,
60°, or 90° elbow.
Horizontal length is calculated by
adding both lengths of horizontal run
(Horizontal Length = H1 + H2).
This is
considered a
vertical elbow.
