CAUTION

IF A SINGLE TUBE GAS SAMPLING PROBE (TG MODEL) IS USED FOR PRESSURE/DRAFT MEASUREMENTS, BE SURE THAT PROBE AND

HOSE ARE CLEAN AND DRY BEFORE CONNECTION TO THE PRESSURE INPUT

Special draft probe (TGD models):

This special probe model has a double gas collector: one for the flue gas analysis and one for the draft measurement.

When you connect the probe to the analyzer you have to insert both gas inlet and pressure inlet connectors. Connect the

hose with line filter to gas inlet connector.

 The pressure measurement requires the instrument in normal operating conditions indicating one of the measured or

calculated parameters. Press [DRAUGHT] on the keyboard. DO NOT INSERT THE PROBE IN THE CHIMNEY. The

internal pump will stop and the following page will be shown:

 Press the [ZERO] key before

insert the probe in the chimney to zeroing the measured value.

 Insert the probe in the chimney. Check for mechanical positioning and flue gas intercepting. Wait for measurement

stabilization.

 Press [ENTER] to memory store the pressure and draft values.

 Press [ESCAPE] (F1) to return to the previous page.

Now you can proceed with the Smoke index measurement and/or the gas analysis. The memory stored value will be

printed together the analysis.

7.3.1 Burner pressure measurement

Using the burner pressure probe, it is possible to measure the pressure on the burner. Connect the probe to the

instrument pressure input and connect to the burner plug. Follow the procedure described in paragraph 8.4 to read the

pressure.

7.4 Smoke measurement

To avoid condensation inside the smoke pump, it should aspirate ambient air before the gas sample. This can be

obtained aspirating the air by the fireside (not in the exhaust gas connection pipe) without using the paper filter.

Introduce now the filter in the pump. The gas sample should be drawn to the center of the combustion gas flux. The

correct gas volume is sampled with 10 uniform shoots by the pump.

Compare the darkening of the filter with the smoke index table. The smoke index found does not exceed the ones

defined by the current normative.

We suggested to use a retaining cone during gas sampling.
