Replace Inducer Motor 11-30-22 arrived and provided and installed new inducer motor housing, gasket, and wiring. Once unit was properly installed. Turned shop heater on and set thermostat to 60 and unit fired off. Checked for CO and measured none. Talked with Dylan about what temperature to leave thermostat set to. He had stated 85 would be nice I informed Dylan that 85 is extremely hot and I would recommend leaving it at 60 . The building is a tin pole shop with little to no insulation. Unit heated from 39 degrees to 48 degrees in the course of the time spent on job. No CO was measured. CPI strongly recommends having chimney cap on exhaust piping to prevent rodents or birds from entering system and having working CO detectors in shop. Replace Inducer Motor
