*Single phase/three phase.
†Indicates automatic reset.
**60,000 and 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.
††An LP kit is available as an accessory. Kit may be used at elevations as high as 2000
ft. If an LP kit is used with Low NOx units, the Low NOx baffle must be removed and
the units will no longer be classified as Low NOx units.
ll Three-phase standard models have heating inputs as shown. Single-phase stan-
dard models have one-stage heating with heating input values as follows:
HJD005-006,HJE004 — 72,000 Btuh
HJE005-006,HJF004 — 115,000 Btuh
HJF005-006 — 150,000 Btuh
***California compliant three-phase models.
†††California SCAQMD compliant low NO

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