The kit includes a 35-foot Flexi-Liner length, round top, flashing with 3-inch collar, mortar guard, fasteners, and instructions — everything needed to complete a single-flue reline job. The liner uses a seamless construction process that increases compressibility, allowing it to ship and store in a slim-line suitcase-style carton. That same seamless build improves rip resistance and overall liner durability compared to seamed alternatives. Licensed chimney professionals and HVAC technicians install this liner as part of a gas appliance venting system upgrade or code-compliance restoration.\u003c\/p\u003e\n\u003cp\u003eThe 1750035 kit is suited for residential and light-commercial masonry chimneys being relined for gas appliance service. Typical applications include relining an existing masonry flue to properly vent a gas furnace, boiler, or water heater where the original flue is oversized, deteriorated, or otherwise non-compliant. The 5-inch diameter and 35-foot length address common single-story and two-story chimney configurations. This kit is specific to gas applications and is not intended for solid-fuel or oil appliance venting without confirming appropriate ratings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSeamless aluminum construction increases compressibility and rip resistance\u003c\/li\u003e\n  \u003cli\u003e5-inch diameter, 35-foot length for standard residential masonry chimney relining\u003c\/li\u003e\n  \u003cli\u003eComplete kit includes liner, round top, flashing with 3-inch collar, mortar guard, fasteners, and instructions\u003c\/li\u003e\n  \u003cli\u003eSlim-line suitcase-style carton for easier jobsite handling and storage\u003c\/li\u003e\n  \u003cli\u003eRated for gas appliance chimney liner applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with gas appliance chimney liner systems in masonry flues requiring relining.

Shut off and lock out all connected gas appliances before beginning liner installation. Confirm the existing masonry flue is clean, structurally sound, and properly sized for the liner diameter before inserting the flexible liner.
