Product Details

Description

The 6-inch to 8-inch B-Vent Increaser is an essential venting component used to transition from a smaller flue pipe to a larger exhaust system. Designed for use with Category I gas-fired appliances, this double-wall metal vent adapter ensures a secure and efficient connection between a 6-inch diameter pipe and an 8-inch diameter vent run. Ideal for HVAC installations involving gas furnaces, water heaters, and boilers, this increaser helps maintain proper draft and safely directs combustion gases out of the home. Its durable construction provides superior heat resistance and structural integrity, making it a reliable choice for professional heating and cooling ventilation upgrades or repairs.
