However, a 120VA.C. power supply is needed for the fan/blower operation.(Do not cut the ground terminal off under any circumstances.)NOTE: Even if the fan is not purchased with the unit, it is still a good idea to bring power to the receptacle box (provided with the unit) in casethe fan is installed at a later date.CAUTION: Label all wires prior to disconnectionwhen servicing controls. Wiring errors can causeimproper and dangerous operation.AERATION ADJUSTMENTThe burner aeration is factory set but may needadjusting due to either the local gas supply oraltitude.
