Installation notes Prepare the heater by powering down and shutting off water flow. Drain water from the header area and replace O rings with clean, lubricated seals. Use a light application of silicone based lubricant approved for pool equipment to aid installation and prevent pinching. Tighten header fasteners to manufacturer torque specifications. If you are not comfortable servicing gas fired equipment consult a certified technician.

Maintenance tips Inspect O rings annually and after any heater service. Avoid petroleum based lubricants. Regular water chemistry maintenance reduces seal degradation and prolongs heater service life.
