    This warranty does not cover sensors damaged through misuse of the analyzer. You should keep the batteries of your 709R fresh so power is con- stantly being supplied to your sensors. The following guidelines will help prevent damage to your sensors: Always use the mini pump filter when testing flue gases.
  • Page 4 Always keep the A794 water trap / filter assembly clean and replace the fil- ter as necessary. Replacement filter part number is A794F. This manual will guide you through the functions of the TPI 709R which will give you many years of reliable service.

    6 hours Operating Time. If a beeping noise is heard during charging disconnect the charger. This is an indication the battery pack needs to be replaced or of something wrong in the charging circuit. Please contact TPI technical assis- tance at 800-368-5719.

  • Page 12: Combustion Analysis Overview

    To ensure accurate and consistent combustion tests, it is important gas and tem- perature samples be taken at the same location. This is easy with the TPI flue probe because the temperature sensor is an integral part of the probe.

  • Page 21: Function 2 - Manometer

    The 709R incorporates a differential manometer. This means when a single hose is connected to the (+) port and pressure is applied, the 709R will read positive pressure. If a single hose is connected to the (-) port and pressure is applied, the 709R will read a negative pressure.
