VERTICAL OR HORIZONTAL VENTING USING SECURE FLEX KITS AND COMPONENTS

Secure Flex venting kits and components may be used in any venting application where rigid Secure Vent (SV4.5) direct vent components can be used. All restrictions, clearances and allowances that pertain to the rigid piping apply to the flexible venting. Secure Flex kits may not be modified; also, under no circum- stances may separate sections of flex pipe be joined together. Secure Flex kits may be added to the end of a vent run made up of rigid Secure Vent (SV4.5) vent sections provided that doing so does not violate any of the venting length, height, routing, horizontal to vertical ratio requirements or clearance con- siderations detailed in this manual.

Secure Flex kits come with an included adapter that can be fitted to the appliance 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 adapter over the previously installed section or appli- ance collar, adjusting the radial alignment until the four locking dimples of the adapter are aligned with the inlets of the four incline chan-

Apply ONLY MIL-PAC BLACK HIGH TEMPERATURE SEALANT (Catalog No. 10K81) to the outside surface of both collars of the adapter (be especially careful to fill the grooves of the outer collar to be covered by the flexible pipe) and slide flexible pipe over inner and outer adapter collars.

nels of the last vent section or collar. Push on the adapter until it fully engages, then twist the adapter clockwise running the dimples down and along the incline channels until they seat at the end of the channels.

Attach the flexible vent to the adapter as follows (see also Figure 44):

A. Install the Inner Flex Pipe -

1.Install the small gear clamp loosely around the inner flexible vent pipe, push it back out of the way.

2.Apply a bead of Mill-Pac Black (700° F) high temperature sealant - Catalog No. 10K81) to the inner adapter collar, approxi- mately ¹⁄₂ inches from the end.

3.Pull and extend the inner flexible vent pipe.

4.Slide the inner flex pipe over the adapter collar. Ensure the flexible vent pipe completely engages the adapter collar to a distance of 1³⁄₄ inch 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 adapter inner collar approximately ³⁄₄ inch from the end of the flex.

6.Install three screws 120 degrees apartthrough the flexible vent pipe and into the adapter collar just below the gear clamp to provide additional security to the connection.

B. Install the Outer Flex Pipe -

1.Install the large gear clamp loosely around the outer flexible vent pipe, push it back out of the way.

2.Apply a bead of Mill-Pac Black (700° F) high temperature sealant - Catalog No. 10K81) to the outer adapter collar; to the grooves of the collar which extend approximately 1 inch from the end and to the flat surface, approximately 1³⁄₈ inches from the end.

3.Pull and extend the outer flexible vent pipe.

4.Slide the outer flex pipe over the adapter collar. Ensure the flexible vent pipe completely engages the adapter collar to a distance of 1³⁄₄ inches 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 adapter outer collar approximately ³⁄₄ inch from the end of the flex.

6.Install three screws 120 degrees apart through the flexible vent pipe and into the adapter collar just below the gear clamp to provide additional security to the connection.

C. Route Flex Vent -

Ensure that the flex vent is properly routed to provide the required clearance. Do Not allow the flexible vent to bend in a radius tighter than 5" (127 mm). Refer to Figure 45. Support horizontal sections of flex with metal straps at 2 foot (0.61 m) intervals.

D. Attach Flex Vent to Termination - Secure Flex components can be purchased separately and attached to bulk lengths of Secure Flex flexible tubing cut to size at the job site. When using this method connect the flex vent only to Flex Vent terminations, not Secure Vent terminations. Secure the flexible vent to the Secure Flex terminations in the same manner (see Figure 44) as it was at- tached to the adapter.

Note: Secure Flex vent must be attached to Secure Flex terminations only. DO NOT substitute Secure Vent terminations or the Secure Vent adapter for Secure Flex compo- nents. The collars of Secure Flex termina- tions and adapters have a different circum- ference than that used with the Secure Vent pipe. Additionally, Secure Flex components have an extended length center tube for use in attaching the flexible vent.
