* Off Heating - This fan delay timing is adjustable (60, 90, 120 or 180 seconds), 90 seconds as shipped.
** Note: The two models above use 10x8 blower assembly instead of 10x6 to achieve a full 4 tons of airflow.
1. These furnaces are manufactured for natural gas operation. Optional kits are available for conversion to propane opera-
tion.
2. For elevations above 2000 ft. the rating should be reduced by 4% for each 1000 ft. above sea level. The furnace must not
be derated, orifice changes should only be made if necessary for altitude.
3. The total heat loss from the structure as expressed in TOTAL BTU/HR must be calculated by the manufacturers
method or in accordance with the "A.S.H.R.A.E. GUIDE" or "MANUAL J-LOAD CALCULATIONS" published by the AIR
CONDITIONING CONTRACTORS OF AMERICA. The total heat loss calculated should be equal to or less than the
heating capacity. Output based on D.O.E. test procedures, steady state efficiency times output.
4. Minimum Circuit Ampacity calculated as: (1.25 x Circulator Blower Amps) + I.D. Blower Amps.
