Vent Configuration: Horizontal Termination with Vertical Rise


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: For this configuration the included thimble assembly is not required and may be discarded.

Vent configurations under 20' (from the base of the fireplace) use 8" dia. Vent.
NOTE: For this configuration the included thimble assembly may be used or use a firestop (not included).

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.
