Product Description

The SELKIRK 174086 is a 4-inch B vent adapter designed to transition from Listed Type B gas vent to Selkirk Flexi-Liner aluminum chimney liner systems. This adapter serves as the mechanical interface between rigid B-vent and flexible aluminum liner, allowing service technicians and installers to connect two different venting components cleanly and securely. It is used in residential gas appliance venting applications where a flexible liner section follows a conventional Type B vent run. Licensed HVAC technicians and chimney professionals are the typical installers for this fitting.

This adapter fits into projects where an existing or new Type B gas vent must transition into a Flexi-Liner flexible aluminum chimney liner. That scenario is common during liner retrofits in existing masonry chimneys, when servicing older homes where rigid B-vent enters a lined flue, or when extending a venting system through a chimney chase. The adapter is listed to work with all brands of Listed Type B gas vent, giving technicians flexibility across multi-brand job sites.

Key Features

  • Transitions from any Listed Type B gas vent brand to Selkirk Flexi-Liner aluminum chimney liner
  • 4-inch diameter fits standard residential gas appliance venting configurations
  • Aluminum construction consistent with the Flexi-Liner product family
  • Compatible across all brands of Listed Type B gas vent for broad job-site applicability
  • Part of the Flexi-Liner system, noted for seamless liner construction and rip-resistant durability

Compatibility

Designed to connect all brands of Listed Type B gas vent to Selkirk Flexi-Liner flexible aluminum chimney liner. Intended for use as part of the Selkirk Flexi-Liner venting system in residential gas appliance installations.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified chimney professional in accordance with the appliance manufacturer instructions and local mechanical codes. Shut off the gas supply and allow the venting system to cool completely before beginning any work on vent components. Verify that all connected Type B vent sections are properly listed and that liner diameter matches the connected appliance venting requirements before final assembly. Do not use this adapter on venting systems other than Listed Type B gas vent transitioning to Flexi-Liner aluminum liner.
