3.3 Connecting the Probe and Thermocouple

Attach the probe and hose assembly to the analyzer as follows (Figure 3-2):

1. Push the yellow banded quick-connect Flue Gas Hose (giving a

slight twist) onto the GAS inlet fitting.

2. Push the blue banded quick-connect Draft Hose (giving a slight

twist) on the “+” pressure fitting.

3. Push the Flue Gas Thermocouple into the T-STACK jack

Important: DO NOT force the thermocouple connector into

its jack. The connection tabs are different sizes, allowing the

connector to fit in only one way.

4. Push the optional combustion-air thermocouple into the T-AIR jack.

Note: The optional combustion-air thermocouple provides

a convenient way to measure the burner’s combustion-air

temperature when its temperature is not the same as room

air. If this thermocouple is not used, then a separate mea-

surement of the combustion-air temperature must be made

using the probe’s thermocouple during the analyzer’s warm-

up period.

Inspect the flue-gas hose for cracks. Replace the hose if it is defective.

Before using the analyzer, check that the Water Trap / Filter is dry and

not dirty. If necessary, dry out the trap and replace the filter element per

Section 5.8.
