Finalizing the Installation
Top Vent Configuration with Vertical Termination
The termination must fall
within the shaded area
shown in the chart. Use
the indicated restrictor
and diffuser positions.
Up to four elbows (45° or
90°) may be used.
Only one horizontal
elbow may be used.
Use 6-5/8" diameter
vent. Attach the 8" to 6-
5/8" reducer (Travis part
# 98900165) to the
fireplace.
This is considered a horizontal
elbow (it does not matter
whether it turns right or left).
It may be a 90° or 45° elbow.
