Trinity │Installation and Operation Instructions Tft Series
Flue Gas Analysis and Adjustment
Each Trinity Tft is factory set to operate with Natural Gas, for boilers field converted to operate with Propane
Gas, a flue gas analysis and adjustment is mandatory. See Table 7-1 and Propane conversion instructions.
Failure to perform the flue gas analysis and adjustment detailed in this section may result
in erratic and unreliable burner operation, leading to reduced efficiency, increased fuel
consumption, reduced component life, heat exchanger combustion deposits, and general
unsafe operation. Failure to follow these instructions may result in serious injury or
death.
Analysis – Perform flue gas analysis, and adjust throttle/input screw as required until CO
2
and CO levels are
within acceptable limits.
