Figure 5-2. Low Battery Indicator

After a low battery alarm occurs, the analyzer will continue to operate for only a

few minutes. The amount of operating time that remains depends on many

factors (e.g., pump and keypad backlight being ON or OFF, and the type and

condition of the batteries).

5.4. Locating Sampling Points

Forced Air Furnace Hot Water Tank

Figure 5-3. Forced Air Furnace

For atmospheric burner or gravity vented,

forced air heating equipment with a clam-

shell or sectional heat exchanger design,

test each of the exhaust ports at the top of

the heat exchanger. The probe should be

inserted back into each of the exhaust

ports to obtain a flue gas sample, before

any dilution air is mixed in.

Figure 5-4. Hot Water Tank

U.S.-made hot water tanks with the ‘bell’

shaped draft diverter can be accurately

tested by inserting the probe tip directly

into the top of the fire tube below the

diverter.
