Horizontal 400 Positive Indoor Adapter Kit

The Hayward Universal H-Series Low NOx is designed specifically for either a positive-pressure or negative-pressure venting system, both have their own factors that determine which one is the best fit.

Positive is based toward a more horizontal venting system, where the heat rises less and therefore causes more condensation that will cause rusting, and possible damage to the pipe.

The Universal H-Series is energy efficient, high performance, and installation adaptable.
