Notes:
1. All heaters are 82% efficient.
2. Cfm values below the minimums and above the maximums shown in this table are not UL/CSA approved, see RT-EB-104 for further details.
3. Air Temperature Rise = Heat Output (Btu) ÷ (Cfm x 1.085).

1. Capacities expressed as MBH (Q) per initial
temperature difference (ITD) between the entering
air temperature to the steam module and the
entering steam temperature. Maximum
recommended operating pressure is 35 PSIG.
