Pa Measurement (Option) - Ecom EN2 Operating Instructions Manual

13.2. 4 Pa Measurement (option)

The simultaneous operation of room-dependent firing place and air
evacuation system can lead to dangerous low pressure conditions.
With the ecom-EN2 it is possible to check the low pressure limit value of
4 Pa and to document in a diagramme 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. 30 sec. and
check low 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 diagramme 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>.
