*Single phase/three phase. Stainless steel models use the same orifices as equiva-
lent standard heat exchangers.
†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. 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.

Cleanable Screen quantity and size varies with option selected.
IIThree-phase standard models have heating inputs as shown. Single-phase
standard models have one-stage heating with heating input values as follows:
048-060, 036 — 72,000 Btuh
048-060, 036 — 115,000 Btuh
048-060 — 150,000 Btuh (shown in heating capacity tables)
***California compliant three-phase models.
†††California SCAQMD compliant low NO
that are controlled to 40 nanograms per joule or less.
NOTE: Capacities for stainless steel heat exchanger units (S/R/T) are the
same as standard units (D/E/F).
