B. Assemble Vent Sections (SLP Only)
To attach the fi rst vent component to the starting collars
of the appliance
• Attach an SLP-DVP24 adapter to the starting collar of
the appliance.
• Lock the vent components into place by sliding the pipe
section onto the collar.
• Align the seam of the pipe and seam of collar to allow
engagement. Rotate the vent component to lock into
place. Use this procedure for all vent components. See
Figure 10.5.
• Slide the gasket over the fi rst vent section and place
it flush to the appliance. This will prevent cold air
infi ltration. High temperature caulk may be used to hold
the part in place.
• Continue adding vent components, locking each
succeeding component into place.
• Ensure that each succeeding vent component is securely
fi tted and locked into the preceding component.
