*FOR INSTALLATIONS AT OVER 5,000 FEET ABOVE SEA LEVEL, CONSULT THE FACTORY
**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.
***Replacement burner trays are built for sea level, natural gas applications unless otherwise specified at the time the order
is placed.
