Hayward UHXNEGVT12506 Negative Pressure Vertical Indoor Vent Kit - 5 inch x 6 inch

What This Part Is Used For
The Hayward UHXNEGVT12506 is a negative pressure vertical indoor vent kit for compatible Hayward pool heaters. It is listed as a 5 inch x 6 inch transition for vertical indoor venting configurations. This kit installs at the heater vent outlet as part of the indoor exhaust routing.
