Option 4 Pa Measurement - Ecom EN3 Instruction Manual

6.4 Option 4 Pa Measurement

The simultaneous operation of room-dependent firing place and air
evacuation system can lead to dangerous low pressure conditions. With the
ecom-EN3 it is possible to check the low pressure limit value of 4 Pa and to
document in a diagram the time course of the low pressure value. Once the
menu point is called up, the measurement is to be performed as follows:
• connect capillary hose for room where burner is installed to „-"
• connect capillary hose for reference place (staircase or outside air to „+"
• operate firing and evacuation systems with maximal performance
• open window resp. connection door to burner room and check the correct
evacuation of the exhaust gases
• zero pressure sensor with <F4>
• position capillary hose for reference location
• start record pressure value course with <F1> (Start) (an acoustical signal
is issued every 30 sec. which can be deactivated / re-activated pressing
<F2>)
• record pressure by opened window resp. connection door
• close window resp. connection door after approx. 30 sec. and check low
pressure
• after approx. 30 sec. open window resp. connection door and check zero
point
• close window resp. connection after approx.
pressure
• after approx. 30 sec. re-open window or connection door and check zero
point
• after approx. 30 sec. close window resp. connection door and check low
pressure
Once the measurement time is completed, the diagram can be viewed on
the display (use <F3> to emphasize illustration 1x, 2x, 4x, 8x times or A for
automatic). Start a printout if needed with <Print>.
