Thermo Products GMC-85, OMC-70 M. Flue Gas Combustion Analysis, Burner Combustion Parameters

All installations and services must be performed by qualified service personnel.

The temperature rise across the furnace heat exchanger operating at steady-state conditions (about 15 to 20 minutes) should not exceed 100°F. The normal comfort range is between 70°F to 100°F. A lower temperature rise usually results in a higher system efficiency.

: If the temperature rise exceeds 100°F, the heat exchanger may fail, voiding the heat exchanger warranty resulting in property damage, personal injury or loss of life.

M. FLUE GAS COMBUSTION ANALYSIS

: Burner adjustments must be confirmed by instrumentation. Failure to use accurate or calibrated instrumentation to correctly setup the burner may result in reduced efficiency, sooting, and/or the production of hazardous carbon monoxide gas.

For typical burner combustion analysis results, refer to the table below.
