It adjusts from 4 inches to 7 inches in depth to accommodate varying wall thicknesses, fitting a 3-inch diameter vent pipe. Fabricated for positive and negative pressure applications, this thimble is tested and listed to UL1738 and S636 standards. It is approved for Category II, III, and IV venting, making it suitable for high-efficiency and condensing appliance installations. HVAC and mechanical contractors install this component when routing a vent through an exterior wall.\u003c\/p\u003e\u003cp\u003eThis wall thimble is used in residential and light commercial installations where a Z-Vent single-wall vent pipe exits through a framed wall assembly. The adjustable depth range makes it practical across standard 2x4 and 2x6 wall construction as well as walls with additional insulation or cladding. It is rated for the demanding flue conditions produced by Category II, III, and IV appliances such as high-efficiency gas furnaces, boilers, and water heaters. The Z-Vent system it supports is engineered AL29-4C stainless steel vent pipe built for condensing flue gas environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAdjustable depth from 4 inches to 7 inches to fit varying wall thicknesses\u003c\/li\u003e\n\u003cli\u003e3-inch diameter, compatible with Z-Vent single-wall vent pipe\u003c\/li\u003e\n\u003cli\u003eAL29-4C special gas vent construction for corrosion resistance in condensing applications\u003c\/li\u003e\n\u003cli\u003eUL tested and listed to UL1738 and S636\u003c\/li\u003e\n\u003cli\u003eApproved for CAT II, III, and IV venting applications\u003c\/li\u003e\n\u003cli\u003eSupports both positive and negative pressure venting systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the Z-FLEX Z-Vent single-wall AL29-4C special gas vent pipe system in 3-inch diameter configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC or mechanical contractor in accordance with the appliance manufacturer instructions and applicable local mechanical codes.
