Venting
A complete approved 4-inch exhaust / 7-inch air intake direct-vent system is required for installation and sold separately. Venting choices remain optional for ordering. Terminations are route alternatives, not items to buy all together; add the proper vent lengths and route-specific installation parts. Follow the exact appliance manual and installer-approved route. A terminal or single pipe kit alone is not a complete system.
