Arrived onsite to perform annual safety and maintenance inspection. Began by testing my inlet gas pressure which gave me a reading of 7.20. Tested my flame sensor which gave me a reading of 4.5. Blower was pulling 4.5A. Inducer was pulling .38A. Tested for CO found none. Measured for my Delta T and got an air temp differential of 60 degrees. Insured everything was working properly upon leaving. Thank you for choosing CPI Plumbing & Heating Inc.
