3.2.2 Using the AC Power Adapter

The AC power adapter is capable of powering the analyzer on a continuous

basis. The adapter plugs into an appropriate 100-240 VAC, 50/60 Hz wall

outlet, and produces an output of +6 VDC. The adapter’s output connector

plugs into the analyzer’s POWER jack located on the botton of the unit

(Figure 3-2).

3.3 Connecting the Probe & Hose Assembly

To attach the probe and hose assembly to the analyzer (Figure 3-2):

1. Push the gas-sample hose connector, the larger of the two

connectors (giving a slight twist), onto the analyzer’s GAS ﬁ tting.

2. Push the draft-hose connector, the smaller connector (giving a

slight twist), onto the analyzers +∆P ﬁ tting.

3. Push the stack-gas thermocouple connector into the T-STACK jack

(connector ﬁ ts in only one way).

4. Push the optional primary/ambient air thermocouple into the

T-AIR jack (connector ﬁ ts in only one way).

IMPORTANT: To assure the accurate calculation of

combustion efﬁ ciency, the optional primary/ambient air

thermocouple must be used when the burner’s primary-air

temperature is not the same as the room temperature.

5. Inspect all hoses for cracks. If any hose is found to be defective,

replace the entire probe and hose assembly. Check that the water

trap is empty, and the ﬁ lter is not dirty or saturated with water.
