• Side vent configurations use 8" (203mm) diameter Simpson Dura-Vent Model Direct-Vent Pro (or GS)*.
• Top vent configurations use 8" (203mm) or 6-5/8" (168mm) diameter Simpson Dura-Vent Direct-Vent Pro (or
GS)*. If using 6-5/8" (168mm) diameter vent, attach the 8" (203mm) to 6-5/8" (168mm) reducer (Travis part #

NOTE: When using 6-5/8” (168mm) diameter vent, make sure to accommodate the 3” (76mm) clearance
above the vent for the first 48” (1219mm) of rise (see vent clearances on page 18). Standard firestops do not
include this clearance.
* Other vent may be approved with this fireplace. Check with the vent manufacturer for details.

Vent Installation
• Slide the vent sections together and turn 1/4 turn until the sections lock in
place.
• Screws are not required to secure the vent. However, three screws may be
used to secure vent sections together if desired.
• High temperature sealant is recommended at the appliance starter section
connection (use high-temperature silicone or Mill-Pac®).
• If disassembly is required, at time of re-assembly check to see if the vent
creates a tight fit. If it does not, apply high temperature sealant to the joints
of the affected sections.
• Horizontal sections require a 1/4" (6mm) rise every 12" (305mm) of travel
• Horizontal sections require non-combustible support every three feet (e.g.: plumbing tape)
