Hayward UHXNEGVT12506 6" Negative Pressure Indoor Vent Adapter for Universal H-Series H250 Heaters
The Hayward 6" 250K Negative Pressure Indoor Vent Adapter (UHXNEGVT12506) is a specialized adapter kit engineered for indoor pool heater installations, particularly for use with Hayward Universal H-Series heaters (such as the H250 model). This adapter facilitates proper venting of combustion gases when the heater is installed indoors, ensuring that exhaust fumes are safely expelled through a vertical vent system.
Features
-
Purpose-Built for Indoor Installations: This kit adapts your Hayward heater’s venting system for indoor use by enabling a negative-pressure vent configuration. It’s essential when your installation requires that the exhaust is directed vertically above the building—typically a minimum of 3 feet above the roof and away from nearby obstructions—to meet safety and code requirements .
-
6" Diameter Design: The adapter is engineered with a 6" vent top, making it compatible with standard 6" diameter vent ductwork. This ensures a secure, leak-free connection that maintains proper negative pressure throughout the vent system.
-
Optimized for Negative Pressure Venting: In indoor installations, negative pressure venting uses the natural draft created by hotter, less dense gases to draw exhaust out of the unit. This method minimizes condensation and potential corrosion in the vent pipe while safely directing exhaust gases outdoors.
-
Comprehensive Adapter Kit: The kit typically includes all components necessary for the conversion, ensuring you have the proper fittings and seals to retrofit your heater’s original vent top for indoor use. It is designed to integrate seamlessly with your existing vent ductwork.
Installation & Considerations
-
Professional Installation: Given the importance of maintaining proper venting for safety and performance, many users opt for professional installation. Ensure that all local codes and manufacturer guidelines are followed during setup.
-
Vent Termination Requirements: The adapter is meant for setups where the vent termination is vertical. If your installation requires horizontally directed exhaust, another system (often a positive-pressure vent system) might be more suitable.
-
Safety & Compliance: Always verify that your indoor venting configuration complies with local building codes regarding clearance, termination location, and overall safety standards related to pool heater installations.
