6Physical data* Capacity in accordance with U.S. Government DOE test procedures.† Gas input ratings are certified for elevations to 2000 ft. For elevations above 2000 ft, reduce ratings 2% for each 1000 ft above sea level.In Canada, derate the unit 5% for elevations from 2000 to 4500 ft above sea level.‡ Airflow shown is for bottom only return-air supply. For air delivery above 1800 CFM, see Air Delivery curve for other options. A filter is required foreach return-air supply.** Low heat CFM when bypass humidifier switch (SW-3) on control center is used.ICS — Isolated Combustion SystemUNIT SIZE 040-14 060-14 080-14 080-20 100-20 120-20OUTPUT CAPACITY BTUH* (ICS) Low Upflow 25,000 37,000 49,000 49,000 61,000 73,000(Shaded capacities are Downflow 25,000 36,000 49,000 49,000 61,000 73,000specified on rating plate) Horizontal 25,000 36,000 49,000 49,000 61,000 73,000High Upflow 38,000 57,000 75,000 75,000 94,000 113,000Downflow 37,000 56,000 75,000 75,000 94,000 113,000Horizontal 37,000 56,000 75,000 75,000 93,000 112,000INPUT BTUH† Low 26,000 39,000 52,000 52,000 65,000 78,000High 40,000 60,000 80,000 80,000 100,000 120,000SHIPPING WEIGHT (Lb) 205 170 182 204 203 234CERTIFIED TEMP RISE RANGE (°F) Low 35 — 45 60 — 70 60 — 70 60 — 70 60 — 70 60 — 70High 40 — 50 45 — 55 45 — 55 45 — 55 55 — 65 55 — 65CERTIFIED EXT STATIC PRESSURE (ESP) Heating 0.10 0.12 0.15 0.15 0.20 0.20(In. wc) Cooling 0.50 0.50 0.50 0.50 0.50 0.50AIRFLOW CFM‡ Heating Low 565 (650**) 515 (590**) 690 (795**) 690 (795**) 860 (990**) 1035 (1190**)Heating High 780 1010 1345 1345 1425 1710Cooling (Max) 1400 1400 1400 2000 2000 2000LIMIT CONTROL SPSTHEATING BLOWER CONTROL (Off Delay) Selectable 90, 135, 180, or 225 Sec IntervalsBURNERS (Monoport) 2 3 4 4 5 6GAS CONNECTION SIZE 1/2-in.
