FURNACE SPECIFICATIONS
1. These furnaces are manufactured for natural gas operation. Optional LP Conversion Kits are available to convert to
propane gas.
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 manufactures method
of in accordance with the "A.S.H.R.A.E. GUIDE" or "MANUAL J-LOAD CALCULATIONS" published by the AIR CON-
DITIONING 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.
