FIGURE 24 DVP Termination Cap
For Vertical Terminations - To locate the flue and
install the flue sections:
• Locate and mark the flue centerpoint on the underside
of the roof, and drive a nail through the centerpoint.
• Make the outline of the roof hole around the centerpoint
nail.
• The size of the roof hole framing dimensions depend
on the pitch of the roof. There MUST BE a 1-inch
(25mm) clearance from the vertical flue pipe to com-
bustible materials.
• Mark the roof hole accordingly.
• Cover the opening of the installed flue pipes.
• Cut and frame the roof hole.
• Use framing lumber the same size as the roof rafters
and install the frame securely. Flashing anchored to
the frame must withstand heavy winds.
• Continue to install concentric flue sections up through
the roof hole and up past the roof line until you reach
the appropriate distance above the roof.
CAUTION: FOLLOW THE REQUIREMENTS OF THE
AGA GAS INSTALLATION CODE FOR MINIMUM
HEIGHT REQUIREMENTS ABOVE THE ROOF.
To seal the roof hole, and to divert rain and snow from the
flue system:
• Attach a flashing to the roof using nails, and use a non-
hardening mastic around the edges of the flashing base
where it meets the roof.
• Attach a storm collar over the flashing joint to form a
water-tight seal. Place non-hardening mastic around
the joint, between the storm collar and the vertical pipe.
• Slide the termination cap over the end of the flue pipe
and rotate the pipe clockwise 1/4 turn (for SL-D Se-
ries) or snap into place (for DVP Series).
