VERTICAL OR HORIZONTAL VENTING USING SECURE FLEX KITS AND COMPONENTS
Secure Flex venting kits and components may be used in any other vent installation where rigid Secure Vent
be used. All restrictions, clearances and allowances pertaining to rigid vent also apply to flexible vent. Do NOT modify Secure Flex kits . Also, do NOT
join separate sections of flex vent together. Secure Flex kits can be installed on the end of a Secure Vent (SV4.5) rigid vent run, provided that doing so
does not violate any of the venting length, height, routing, horizontal to vertical ratio requirements, or clearance considerations detailed in this manual.
Secure Flex kits come with an included adaptor that can be installed on the fireplace collar or the inclined channel end of the last Secure Vent (SV4.5)
vent section in a rigid system in the exact same fashion as any other Secure Vent section. Align the dimpled end of the adaptor over the previously
installed section or fireplace collar, adjusting the radial alignment until the four locking dimples of the adaptor are aligned with the inlets of the four
incline channels of the last vent section or collar. Push on the adaptor until it is fully engaged, then twist the adaptor clockwise running the dimples
down and along the incline channels until they seat at the end of the channels.
Apply ONLY MIL-PAC BLACK
SEALANT (P/N 10K81) to
the outside surface of both
collars of the adaptor (fill the
grooves of the outer collar to
be covered by the flexible pipe)
and slide the flexible vent over
the inner and outer adaptor collars

NOTE:Outer vent pipe is pulled away
to show inner vent pipe details.
• Install the Inner Flex Pipe.
1. Install the small gear clamp loosely around the inner flexible
vent, then push it back out of the way.
2. Apply a bead of Mill-Pac Black (700 °F) high temperature
sealant (P/N 10K81) to the inner adaptor collar, approximately
1/2" from the end.
3. Pull and extend the inner flexible vent.
4. Slide the inner flex vent over the adaptor collar at least 1 3/4".
5. NOTE: Ensure the flex vent is free from damage or tears.
6. Slide the gear clamp down and tighten it fully to secure the
flexible vent to the adaptor inner collar approximately 3/4"
from the end of the flex.
7. Install three (3) screws 120° apart through the flexible vent
and into the adaptor collar just below the gear clamp to provide
additional security to the connection.

• Install the Outer Flex Pipe.
1. Install the large gear clamp loosely around the outer flexible
vent pipe, then push it back out of the way.
2. Apply a bead of Mill-Pac Black (700 °F) high temperature
sealant (P/N 10K81) to the outer adaptor collar. Cover to the
grooves of the collar that extend approximately 1" from the
end and to the flat surface, approximately 1 3/8" from the end.
3. Pull and extend the outer flexible vent.
4. Slide the outer flexible vent over the adaptor collar. Ensure the
flexible vent completely engages the adaptor collar 1 3/4" from
the end, and that it is free from damage or tears.
5. Slide the gear clamp down and tighten it fully to secure the
flexible vent to the adaptor outer collar approximately 3/4"
from the end of the flexible vent.
