Before using this meter, read all safety information carefully. In this manual the word “WARNING” is used to indicate
conditions or actions that may pose physical hazards to the user. The word “CAUTION” is used to indicate conditions or
actions that may damage this instrument.
WARNING!
This analyzer extracts combustion gases that may be toxic in relatively low concentrations. These gases are exhausted
from the back of the instrument. This instrument must only be used in well-ventilated locations.It must only be used by
trained and competent persons after due consideration of all the potential hazards.

To change the temperature scale from °F to °C (or back) perform the following steps;
• Start with the SmartBell PLUS Off
• Rotate the selector to “˚F/˚C”
o The current scale will initially be displayed
o The unit will switch to the alternative scale
• Rotate the selector to the desired fuel for your testing
• Allow the unit to complete the zero process
Note: These steps are only required one time, or when the scale needs to be changed.

To correctly calculate net temperature and combustion efficiency it is important to have the correct inlet tempera-
ture set. Two methods are available to properly establish the inlet temperature
• Non-ducted systems. If the SmartBell PLUS is being used on a system that uses combustion air from the space
near the appliance simply turn the analyzer on without the flue probe connected. The SmartBell PLUS will use an ambi-
ent sensor inside the handset as the inlet temperature to determine net temperature.
• Ducted systems. If the SmartBell PLUS is being used on a system that brings in outside air for combustion air it
is important to set the inlet temperature prior to taking flue gas readings. To properly set inlet perform the following steps
during startup.
1. Connect the flue temperature connector only to the SmartBell PLUS
2. Place the flue probe in the combustion air inlet stream (you will need to drill a 1/4” hole for access)
3. Turn on the SmartBell PLUS and allow to complete the zero process.
4. Connect the flue gas connector to the SmartBell and proceed to combustion measurements
• The temperature measured during the zero countdown has now been stored, and will be used to determine
the net temperature.

When powering the SmartBell PLUS on, simply rotate the selector to the desired fuel. The display will show this display,
and then it will complete the zero process.
Note: If you wish to use the same fuel as previously selected rotate the selector to “StandBy” at power on. The fuel in use
will be displayed and then blink. If the fuel is not correct rotate the selector to the proper choice before the Zero
countdown starts.
