*FOR INSTALLATION AT OVER 2,000 FEET ABOVE SEA LEVEL, DERATE 4% PER I,000 FEET ABOVE SEA LEVEL. Refer to the heater's rating plate.
**WARNING: The Hydraulic conditions or water chemistry that caused the tube bundle to fail have very likely also damaged the bypass valve and Unitherm Governor. We
recommend you replace the Unitherm Governor and inspect the bypass assembly. Failure to do so could cause premature failure of this replacement part.
***WARNING: Copper and Cupronickel heat exchangers and tube bundles are not interchangeable. Units with suffix "C" must use copper replacement parts and units with
suffix "X" must use Cupronickel replacement parts.
