How does this blower handle pool chemicals and saltwater?

This blower is manufactured with materials and finishes that resist corrosion common in pool environments. That helps extend service life when used in conjunction with proper heater maintenance and water chemistry management. It is not a substitute for routine inspection or for addressing leaks and ventilation issues.

• Corrosion-resistant construction for saltwater and chlorinated systems
• Durable components to minimize premature wear in harsh conditions
• Suitable for indoor and outdoor installations when protected per heater instructions

What performance and plumbing details should installers know?

The blower works with the Universal H-Series’ engineered heat transfer and plumbing layout to maintain intended water velocity and efficiency. The heater family features cupro-nickel heat exchanger technology and CPVC union plumbing, which combined can reduce pump runtime and improve overall heating performance when systems are sized and installed correctly.

• Designed to maintain proper combustion air for cupro-nickel heat exchanger systems
• Heater plumbing uses 2" x 2½" CPVC unions for straightforward connection
• When paired with factory systems, can help the heater achieve intended energy and runtime savings

How should this replacement be installed and maintained?

Replacement of the combustion blower should be performed by a qualified service technician following Hayward’s installation guidelines and local codes. Proper installation ensures safe combustion, correct venting, and the heater’s low-NOx emissions performance. Regular seasonal checks will help preserve function and safety.

• Professional installation recommended to ensure correct airflow and safety
• Follow heater manual for venting, gas connection, and electrical requirements
• Periodic inspection and cleaning recommended to prevent debris buildup and maintain efficiency
