• Apply high-temperature silicone to the female section of inner pipe (on the lower secton of vent) so
the silicone seals the inner pipe from the outer pipe when the sections are assembled. Slide the
sections together and turn 1/4 turn until the sections lock in place. Install three metal screws through
each joint to lock the outer section in place (see the instructions included with the vent for further
details).
• Horizontal sections require a 1/4" rise every 12" of travel
+ Exterior Vent Diameter = 6 5/8", Inner Vent Diameter = 4"
• Horizontal sections require non-combustible support every three feet (e.g.: plumbing tape)

Acceptable Vent Configurations

Restrictor Plates

• Certain vent configurations require a restrictor plate. There are four restrictor plates included with
the fireplace. Each restrictor is either a #1 (small) or #2 (large) and is for vertical or horizontal
terminations. On vertical terminations the restrictor plate fits into the final section of pipe (the
section that attaches to the termination). On horizontal terminations the restrictor plate fits into the
vent cap. Failure to install a restrictor plate, when required, will lead to flame lifting and a
potentially dangerous situation.
