Product details

The Hayward UHXNEGVT14008 is the 8 inch negative pressure vertical indoor vent adapter kit for Hayward H400 Universal heaters.

What it does

The kit is for indoor heater venting applications, and also for outdoor heaters that are under a roof cover. Heaters come with an outdoor top, and the tops are 8 in. in diameter for all indoor venting applications. The kit adapts the heater to a negative pressure vertical vent.

Negative or positive pressure

A heater of this type can be vented with either a negative pressure or a positive pressure system, and the right choice depends on the site, the vent termination needs, horizontal or vertical, and the cost of the venting system. Negative pressure is for a vertical or almost straight up vent pipe, where heat rise creates lift and little condensation forms in the pipe. Positive pressure is for a more horizontal vent, where heat rise is less and more condensation can form, which can cause rusting and damage.

Before you order

This kit replaces old part number UHXNEGVT14001. See the installation instructions for the limitations of each venting system.
