DIRECT VENT SYSTEM COMPONENTS
The following "Security Secure Vent TM " or "Simpson Dura-Vent" brand Direct-Vent components may be safely used with these appliances.
Model # SECURITY SECURE-VENT - Description
IMPORTANT NOTE: Seal the fi rst section of pipe to the stove collar using mill-pac black, high temperature sealant.
Note: 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 back-pressure by creating natural draft in the snorkel.
