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.
