Notes:
1. For cfm values outside these ranges, refer to RT-EB-104.
2. Refer to Table 35-3 for availability of electric heat kw
ranges by voltage.
3. 20-30 Ton models are single circuit, 40 Ton models are
dual circuit.
4. The firing rate of the unit can vary from 33% of the
Heater Mbh up to the nameplate rating of the unit.
5. The firing rate of the unit can vary from pilot rate of
125,000 Btuh up to the nameplate rating of the unit.
