(1)
Wire size should be determined in accordance with National Electrical Codes. Extensive wire runs will require larger wire sizes.
(2)
Maximum Overcurrent Protection Device: May use Time Delay Fuse or HACR type Circuit Breaker of the same size as noted.
(3)
See Installation Instructions for appropriate vent diameter, length and number of elbows.
1.
These furnaces are manufactured for natural gas operation. Optional Kits are available for conversion to propane gas operation.
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 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.
Unit specifications are subject to change without notice. ALWAYS refer to the unit's serial plate for the most up-to-date general and electrical information.
