Regency Direct Vent System (Flex)
Snorkel Terminations
Horizontal Terminations Only
Snorkel Terminations:
These venting systems, in combination with the P48 Direct Vent Gas
Fireplace, have been tested and listed as a direct vent heater system
by Warnock Hersey. The location of the termination cap must conform
to the requirements in the Vent Terminal Locations diagram.
For installations requiring a vertical rise on the exterior of the building, 14-
inch and 36-inch tall Snorkel Terminations are available. Follow the same
installation procedures as used for standard Horizontal Termination.
NEVER install the snorkel upside down.
FPI Direct Vent (Flex) System Termination Kits include all the parts
needed to install the P48 using a flexible vent.

Below Grade Snorkel Installation (Dura-Vent Only)
If the Snorkel Termination must be installed below grade, i.e. basement
application, proper drainage must be provided to prevent water from
entering the Snorkel Termination. Refer to Rigid Pipe Installation
instructions for details. Do not attempt to enclose the Snorkel within the
wall, or any other type of enclosure.
