1. Information
1.1 Certification
The FG4200 flue gas measurement device is tested according to the requirements of the
European standard EN 50379 Parts 1 and 3.
1.2 Usage
The FG4200 flue gas measurement device is suitable for measuring combustion parameters
of heating systems. It is not suitable for use as a continuously operating gas warning and
alarm device.
Any use of this device requires full understanding and compliance with these operating in-
structions, the relevant standards, as well as the relevant statutory regulations.
The device is intended only for the uses described in this manual. Any improper use of the
device may lead to electric shock or destruction of the measuring device!
Always fully charge the FG4200 via the USB interface with a 5 V DC / 1 A USB power
supply adapter only.
Incomplete charging affects the charging capacity of the battery in the long term.
When charging, no measurements should be performed.
The displays shown in this manual are examples.
Only recorded measurements can be printed or saved.
The device employs fuel-specific formulas to calculate CO2 and qA (flue gas loss) combus-
tion parameters. For this reason, these combustion parameters can only be calculated for
the fuels which are saved in the fuel table of the device. The following fuels can be set:
Light fuel oil, natural gas, LPG propane, heavy fuel oil, pellets, wood, brown coal, hard coal,
coal briquettes, coal coke, anthracite, biogas, LPG butane, coal gas, coke oven gas.
The lifetime of the sensors used in the FG4200 is typically 4 years for both the O2 sensor
and the CO sensor. The pressure sensor has no limited lifetime under normal-use condi-
tions.
To avoid influencing the measuring accuracy of the sensors, the FG4200 must not be ex-
posed to solvents, fuels or plasticizers during operation and storage.

en
1.3 Maintenance
To ensure proper function and accuracy, calibration and adjustment should be performed
once a year. Device maintenance must only be carried out by trained service personal.
1.4 Disposal according to WEEE
Since 2005, EU-wide regulations apply to the disposal of electrical and electronic de-
vices. In essence, these regulations set out that collection and recycling options should
be available for households. Because the FG4200 is not registered for use in private
households, it must not be disposed of through such channels. The devices can be returned
to your national retailer or to your national Dräger Safety Organization for disposal. Please
contact Dräger MSI GmbH, if you have any questions regarding disposal.

3. First time use and general operation
3.1 Preparation for first time use
Before using the measuring device, the integrity of all components must be checked, e.g.:
 Device exhibits no visible damage
 No condensed water in the gas preconditioner
 The gas preconditioner filter is clean
 Gas hoses without defects
 Visual inspection of the probe
Connect the quick-release hose coupling of the flue gas probe into the gas inlet G of the
measuring device and the jack plug of the flue gas probe in the temperature input T of the
measuring device. Ensure before each measurement that a clean filter is inserted in the gas
preconditioner!
Only turn the FG4200 on, if the flue gas probe is located in fresh air. The null signals of the
sensors are matched with the fresh air.
3.1.1 Prior to each measurement
The air-tightness of the gas path can be tested easily: Close the gas inlet of the probe with
the round cap. If the gas path is not leaking, the pump should now deliver more power. The
sound of the pump changes accordingly. If no change occurs, then the gas path must be
checked with a gas flow meter.
3.1.2 Touch screen
The FG4200 is controlled by a touch-sensitive display (touch screen). You can execute typ-
ing and scrolling functions on the screen using your finger or a plastic pen. Ball-point pens,
pencils, metal pins, etc. are not suitable.
Because the display contains a resistive touch screen, slightly more pressure must be ap-
plied during operation compared with today’s smartphones with their capacitive touch
screens.
Menus and lists can be moved up and down by up/down swiping gestures (scrolling).
Menus and lists positions are highlighted by tapping. The selected item is activated via the
selection button or by tapping again.
Touching the display with sharp or pointed objects may lead to the destruction of the
display.

6.3 Measuring combustion air temperature
The FG4200 will now ask you to measure the combustion air tempera-
ture. Place the flue gas probe in the inspection opening of the combus-
tion air intake or alternatively hold the flue gas probe in the room air.
As soon as the combustion air values have stabilized, press Hold. If an
oxygen content of less than 21% is measured in the combustion air
supply, this implies under circumstances a leak in the exhaust pipe in
the air-exhaust system.
6.4 Flue gas measurement
Within the exhaust stream, there are areas which only partially mixed
with exhaust. For this reason, it is necessary to take the sample from
the flow centre. The flow centre is characterized by maximum flue gas
temperature and minimum oxygen concentration.
Press the arrow button >>, once the combustion air measurement is
complete.
Now insert the flue gas probe into the exhaust pipe, move it in the ex-
haust stream and position it so that the tip of the sensor is the flow
centre (maximum gas temperature, minimum oxygen concentration).
After you've found the flow centre and the measurement values have stabilized, fix the flue
gas probe in this optimal position with the sensor cone. A summary of currently measured
combustion values is then displayed. Then press the Hold button and then the arrow but-
ton >>. By pressing the arrow button >> again, you can display the other measurement
results.
6.5 Average value measurement
The German regulation 1st BImSchV calls for simultaneous determina-
tion of oxygen content and temperature of flue gas as an average over
a time period of 30 seconds. If average measurement is enabled in the
settings, you can begin the 30-second averaging process by pressing
Start, no need to press Hold.

6.6 Draft measurement
If draft measurement is enabled in the settings, the draft (differential
pressure) of the flue gas can be measured. This requires moving the
flue gas probe from gas inlet G to pressure connection P.
6.7 Entering combustion system data
If the input of combustion system date has been enabled in the device
settings, the boiler temperature, the smoke numbers and the appear-
ance of oil derivatives can be entered. It is only necessary to enter
smoke numbers and oil derivatives in case of combustion with fuel oils
(light fuel oil and heavy fuel oil) and are only available for measure-
ments with these fuels. Once the input data is complete, press the ar-
row button >>.
The result summary is then displayed and can be scrolled through using
the arrow buttons << / >>.

7. Ambient air CO measurement
In some countries exists a regulation, to measure ambient air CO at the
site of a combustion to prove their tightness. For this, the FG4200
needs no external CO sensor. At a place with fresh air, without CO
content, the value has to be 0 ppm. Is the reading not 0 ppm, pull off
the tube of the gas probe from the device, wait for a while with running
pump and push Zero. Confirm the request with Yes and the displayed
value will become zero. This zero point is independent from the CO
zero point of normal gas flue measurements. Slip the hose on the gas
inlet again. After pushing Hold and the arrow button >> the documen-
tation menu may be called.
8. Pressure measurements
8.1 Connection diagram
For pressure measurement up to 160 mbar (gas, nozzle or kinetic pres-
sure), connect the measuring point using the burner pressure hose with
the pressure input P of the measuring device.
8.2 Pressure measurement
