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).

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.
