and CAN/CSA B142.2 (in Ca
3 Minimum Circuit Ampacity = (1.25 x Circulator Blower Amps) + I D Blower amps. Wire size should be det ermined in accordance with National Elect rical Codes.
Ext ens ive wire runs will require larger wire sizes.
4 Maximum Overcurrent Protection Device refers to maximum recommended fuse or circ uit breaker size. May use fuses or HACR-type circuit breakers of the same s ize as noted.
Notes:
• All furnaces are manufactured f or use on 115 VAC, 60 Hz, single-phase elect rical supply.
• G as Service Connect ion ½" FPT
• Important : Size fuses and wires properly and make electrical connections in ac cordance wit h t he National Elect rical Code and/ or all exis ting local codes.
NOTES:
* These furnaces are manufactured for natural gas operation. Optional Kits are available for conversion to propane gas operation.
* 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.
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.
