N/A

• All furnaces are manufactured for use on 115 VAC, 60 Hz, single-phase electrical supply.
• Gas Service Connection 1/2" FPT
• Important: Size fuses and wires properly and make electrical connections in accordance with the National Electrical Code and/or all existing local codes.
• For bottom return: Failure to unfold flanges may reduce airflow by up to 18%. This could result in performance and noise issues.
• For servicing or cleaning, a 24" front clearance is required. Unit connections (electrical, flue and drain) may necessitate greater clearances than the minimum clearances listed above. In all cases, accessibility clearance must take precedence over clearances from the enclosure where accessibility clearances are greater.
