Hayward Industries of Nashville, Tenn., is recalling about 300 Hayward Vent Kits sold in the U.S., Canada and Mexico.

The recalled vent kits installed on gas pool heaters are not the proper size and can allow carbon monoxide to leak, posing a CO poisoning hazard.

No incidents or injuries have been reported.

This recall involves the Hayward UHXNEGVT15001 Negative Pressure 6-inch Vent Kit for pool heaters.

The vent kit is used exclusively on the Hayward H500FD Gas Heaters and includes one vent pipe adapter for negative pressure galvanized vent pipe, one flue cover plate with hole for vent, #10 sheet metal screws, vent pressure switches, vent pressure switch tubing and vent pressure switch jumper wire.

Only Hayward H500FD Gas Heaters that are installed indoors and use 6-inch negative pressure galvanized vent piping are affected by this recall.

The name Hayward is stamped into the furnace housing above the water pipes. The model and serial number H500FD is located to the left of the water pipes.

The vent kits, manufactured in the U.S., were sold at pool equipment distributors nationwide and online at and from March 2015, through April 2019, for about $265.

What to do

Consumers should immediately turn off the pool heater and contact Hayward for free replacement and installation of a new vent kit and not use the pool heater until a new vent kit is installed.

Consumers may contact Hayward Industries toll-free at (888) 847-8717 from 8 a.m. to 6 p.m. Monday through Friday, or online at for more information.
