An LP conversion kit should not be used on alow NOx unit because then it can no longer be classified as a Low NOx unit. TheLow NOx requirement only applies to natural gas units.Three-phase standard models have heating inputs as shown. Single-phase standardmodels have one-stage heating with heating input values as shown in heatin capac-ity tables.***These units do NOT meet the California low NOx requirements.†††California SCAQMD compliant low NOx models have combustion products that arecontrolled to 40 nanograms per joule or less.48HE,HJ
