Installation & Compatibility Notes

Prior to installation, shut off the heater, ensure no pressure in the lines, and allow it to cool. Remove the old header assembly and inspect surrounding castings and connections. Clean all seal surfaces and re-install the replacement header assembly ensuring alignment and full sealing. After installation, restore service and confirm proper operation without leaks or restrictions.

Maintenance Tips

Check for signs of corrosion, cracking or leakage at the header assembly during scheduled maintenance.
If heater flow drops or heat output decreases, inspect the header for wear or damage as part of your diagnostics.
Seal surfaces and connections should be cleaned and re-tensioned if the unit is serviced again.

Why Choose This Assembly?

For pool service professionals and advanced homeowners, this replacement header assembly offers an efficient way to restore the integrity of a Universal H-Series Low NOx heater. Instead of replacing the entire unit, the right header restoration can get the system back in service quickly and reliably.
