Operating Instructions Dräger FG4200
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 CO
and qA (flue gas loss) combus-
2
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.
