1.
These furnaces are manufactured for natural gas operation. Optional kits are available for conversion to propane operation.
2.
Minimum Circuit Ampacity calculated as: (1.25 x Circulator Blower Amps) + I.D. Blower Amps. Wire sizes should be determined in accordance
with National Electrical Codes.Extensive wire runs will require larger wire sizes.
3
Maximum Overcurrent protections Device refers to maximum recommended fuse or circult breaker size. May use time delay fuses or HACR-
type circuit breakers of the same sizes as noted.
NOTES:
1.
For elevations above 2000 feet the rating should be reduced by 4% for each 1000 feet above sea level. The furnace must not be derated,
orifice changes should only be made if necessary for altitude.
2.
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.
