United States Stove Company 4840 Mode D'emploi page 7

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. Termination clearances as shown in the "Vent Termination
Clearances" section.
