A 120 VAC, 15 Amp, 1 ph, 60 Hz circuit is required for operation of the integral circulating pump and a 120 VAC, 15 Amp, 1 ph, 60 Hz circuit for the appliance controls are recommended. If a single electrical service is provided to operate both the controls and pump, a 120 VAC, 30 Amp, 1 ph, 60 Hz circuit is recommended. The combustion air blower motor operates on 230 VAC, 3 ph, 60 Hz. This three phase voltage is generated by the variable frequency drive (VFD) and supplied directly to the blower motor. NOTE: No 230 VAC electrical service is

required for operation of the combustion air blower.
