NOTES:
1. Heating capacity based on annual fuel utilization efficiency rated by manufacturer.
2. On all outlet and inlet dimensions, the first dimension is width.
3. To permit largest recommended air conditioning (at .5 static pressure), selection of the highest motor speed is
required.
4. Electrical characteristics at 115 volts, 60 Hz., 1 phase (less than 15 amps, for all models).
5. All specifications are subject to change without notice.
