1.
DirectVent Pro pipe and fittings are designed with
special twist-lock connections. To connect the
venting system to the appliance flue outlet, a twist-
lock Appliance Adaptor is required. The adaptor will
be supplied for installation in the field. Assemble the
desired combination of Pipe Sections and Elbows to
the Appliance Adaptor.
Notes:
• Twist-lock procedure - Line up locking lugs on male and
female ends of pipe sections. Insert the male end of pipe
into the female end until the locking lugs are covered.
Twist the female end clockwise an eighth of a turn to
lock sections together. Three screws are required to
secure the joint, ensure they do not penetrate the inner
wall of the vent pipe.
• Horizontal runs of vent pipe must be supported to
prevent any downward sags. Horizontal pipe sections
should be supported at least every 4 feet. Wall Straps
can be used for this purpose.
• Seal all joints with high temperature silicone.
2. With the appliance adaptor and pipe section
attached to the appliance, slide the appliance into its
correct location, and mark the wall for a hole of the
appropriate size. The center line of the pipe should
line up with the center of the hole. Cut and frame
the hole in the exterior wall where the vent will be
terminated. A Wall Thimble is required.

Notes:
• The horizontal run of venting must be level, or have a 1/4
inch rise for every 1 foot of run towards the termination.
Never allow the vent to run downward. A downward
slope can trap heat and become a possible fire hazard.
• The location of the Horizontal Vent Termination on an
exterior wall must meet all local and national building
codes, and must not be easily blocked or obstructed.
