⊗ Snorkel Caps: These are elongate vent termination caps, which incorporate the principles of natural draft into a horizontal installation. Two styles
are common, 14” and 36” (Cap height). They enhance draft and relieve backpressure by creating natural draft in the snorkel.
⊕ Horizontal Caps: This 13 ½” square horizontal cap is placed on the outer wall of the dwelling. Not to be within 9” of an air inlet or within 12” of the
ground. It requires a minimum 2’ rise on the interior pipe.
• Vertical Termination Cap: Low profile and high wind caps can only be used on vertical pipe installations.
