It creates the required clearance between the vent pipe and surrounding wall materials, reducing fire risk and maintaining code-compliant installation. Sized for 10-inch B vent pipe, it also accommodates 8-inch all-fuel vent systems where applicable. Licensed HVAC technicians and mechanical contractors typically install this component during new construction and vent system retrofits on gas-fired appliances.\u003c\/p\u003e\n\u003cp\u003eThis wall thimble is suited for residential and light commercial applications where a Type B double-wall vent must penetrate an exterior or interior combustible wall.
