12.Introduction
2.1 The flue gas analyzer HT-1200N
The Flue Gas analyzer HT-1200N is used for the following purposes:● Precise control and adjustment measurement for gas and oil firings● Inspection of gas firing locations● Control of modern combustion boilers
2.2 Important Instructions regarding the Operating Manual
The operational manual is an important part of the scope of supply and assures
not only the correct operation and use of the measuring device,but also the safetyof the user and the environment.
Therefore,every user is obliged to read carefully the operation manual and to strictly
observe all instructions regarding safety.
Additional instructions in other chapters are marked through Caution signs.

3.Safety Regulations
The following Safety instructions have to be strictly observed.
They are an essential and indispensable part of the user documentation.
Not observing can mean loss of warranty claims.
3.1 Safety Instruction● The device HT-1200N is only to be used for its indicated purpose:
The measurement of flue gases, of combustion air and gas temperature.
3.2 Specific Safety Instructions● The device is only to be used with the supplied AC adapter (HT1301) for
power supply.
Should the battery catch fire due to an operating error or a technical defect,
the fire should only be extinguished with the corresponding fire extinguishingequipment.
● The metal tube of the probe as well as any other metal parts / accessories are
not to be used as electric conductors.
● The device is not to be used in and under water.
● The device is not to be placed near or directly at open fire or heat.
● The indicated range of temperature of the probe is not to be exceeded,as the probe, temperature sensory mechanism and sensor could be destroyed.
● Plugs of the electronic measuring device have to be avoided.
● Caution: Moisture, being evacuated out of the condensate trap can beslightly acidic.
● In case of skin contact IMMEDIATELY: clean respective parts of the body!
Avoid contact of eyes with liquid!
● After measurement, vent the device with fresh air and see to it that the probe isgetting cold.As long as it is hot, the tube of the probe could burn persons or cause
fire damages on inflammable underground.
● The exhalations of alcoholic combinations(f.ex.attenuation, petrol, spirit,varnish.....) may be damage the sensor of the analyzer. Therefore it’ s forbidden
to preserve or use these fluids near by the device.

4.1 Perspective View

HT-1200N can be operated by:
1. HT-internal battery(standard scope of supply)
2. HT-battery charge (standard scope of supply) 100V / 12 Vdc / 100mA

If the battey is fully charged, the HT-1200N changes to trickle charge
75.3%
and the LED blinks approx. every 16 seconds.
The charging time for unloaded battery is approx.12 hours.
● Attention: No battery charge if the unit is switched ON.(measurement)● For battery charge, the device has to be switched OFF and the HT battery charger
has to be connected to the HT-1200N and the mains power supply.
● Also in case of non-use charge battery once in the month.

Condensate trap
● Mount condensate trap with filter.
● Please check, if the condensate trap is empty and the filter is still white.
● Check all plugged and screwed connections regarding their tight and correct fit.
Check tightness of all tubes,tube connections and condensate trap(from probe tip
to gas connection on device).
