Hayward recalls vent kits for H500FD gas pool heaters due to carbon monoxide leakage. Stop using the heater and contact Hayward for a free replacement.
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 to consumers.
Hayward Industries is recalling specific negative pressure vent kits installed on H500FD gas pool heaters because they are the wrong size, which can allow carbon monoxide to leak into living spaces.
