*Stainless steel models use same orifices as equivalent standard unit.
†Indicates automatic reset.
**≤72,000 Btuh heat input units have 2 burners. 90,000 and 120,000 Btuh heat
input units have 3 burners. 115,000 Btuh heat input units and 150,000 Btuh Heat
input units have 3 burners.

low NOx unit because then it can no longer be classified as a Low NOx unit. The
Low NOx requirement only applies to natural gas units.
Three-phase standard models have heating inputs as shown. Single-phase standard
models 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.

x
models have combustion products that are
controlled to 40 nanograms per joule or less.
