4.3.3 Starting a Combustion Test
Operation
Important! If the burner’s primary-air temperature is not
the same as the room temperature, then be sure the Optional
Room Air / Primary Air Thermocouple is installed per
Section 3.3.
1. With the Combustion Test Screen (Section 4.7) displayed and the probe
installed in the stack, press the
RUN
key to start a combustion test.
2. Once all sensor readings are displayed: A) Loosen the thumbscrew on
the probe stop. B) Move the probe in and out of the stack until the
highest stack temperature (TS) reading is obtained. C) Tighten the
thumbscrew to prevent further movement of the probe.
Alternately, the highest stack temperature can be located by display-
ing the Draft Screen (Section 4.9) and adjusting the probe for the
highest HOT SPOT reading.
Note that locating the highest stack temperature is very important for
accurate combustion calculations.
3. You can now begin burner-service procedures. The readings on the
analyzer change quickly to show changes in burner performance.
CAUTION
With the Water Trap / Filter Assembly stood up on its Outlet
End, do not let water condensate build up beyond the tip of
the riser tube. The sensors could be damaged if water would
enter the analyzer. Drain the water condensate after every
combustion test (refer to Section 6.4).
4. Pressing the
ENTER
key will save the Combustion Test Screen readings
while a test is in progress. Moving the cursor (
z
) in front of the print
( P) function using the
s
key, and then pressing
ENTER
will print the
current test information to an optional printer.
4.3.4 Ending a Combustion Test
1. Press the
RUN
key to end a combustion test. You should hear the pump
stop running.
WARNING!
Burn hazard! Allow a hot probe to cool before handling.
