Notes:
• All gas heat BTU based on product specification output values.
• All electric heat BTU based on 3412 BTU per Kw at 240VAC. If another voltage is used
the BTU value must be taken from the EHB.
• All Kw listed are single phase kits.
• All S15 limits open at 150° F.
• Pocket formulas (must be rounded to iHarmony increments).
• CFM = BTU / 1.08 / Target Temp Rise
• Temp Rise = BTU / CFM / 1.08.
