                APX399 and APX500 Boiler models are factory shipped as Natural Gas builds and have to be field adjusted for LP   
                gas application.  Refer to ‘System Start- Up Section of this manual for detailed procedure. 
                APX800 Boiler Model is factory shipped as either Natural Gas build or LP gas build. 
                Ratings shown are for installations at sea level and elevations up to 2000 Feet.  For elevations above 2000 Feet,    
                ratings should be reduced at the rate of two and half percent (2.5%) for each 1000 Feet above sea level.
