Section 2. Setup
2.1. Connecting the Probe and Thermocouple
A rigid stainless steel probe with handle is connected to a flexible hose with an
integral water-trap / filter used to draw a gas sample into the analyzer from the
room, grills, diffusers, and furnace flues. Refer to page 6.
1. Inspect the sample gas hose for cracks. If a hose is defective, replace the
entire probe assembly.
2. Before using the analyzer, check that the water trap/filter is clean and dry.
If necessary, dry out the trap and replace the filter element (see page 81).
3. Push the probe’s sample gas hose onto the GAS inlet connector.
4. Push the probe’s draft hose (+ ∆P) onto the “+” pressure connector.
5. Push the probe’s thermocouple into the T-STACK connector on the
instrument, noting its orientation.
IMPORTANT: The T-STACK connector tabs are keyed to fit
into the connector in only one orientation. DO NOT force the
thermocouple connector tabs into the T-STACK connector.
6. Push the optional ambient/primary-air thermocouple into the T-AIR
connector.
NOTE: Refer to page 6
