Checking Operating Pressure:
WARNING:
The regulator that is supplied with the fire MUST NOT BE REMOVED.
Removal of the regulator, or replacing it with one not intended for use with an Escea fire,
will void the limited appliance warranty.
The regulator is adjustable. The operating pressure must be checked and adjusted if
necessary.
This is done at the regulator located at the front LH corner of the appliance.
This is best done before the fascia panels have been fitted to avoid fascia damage.
Pressure test points are available for both inlet and operating test pressure (as shown
below).
1)
Remove inlet pressure test point screw and attach manometer tube.
2)
Run the fire on full and measure inlet pressure with all the other gas appliances
running. If pressure does not fall within the maximum or minimum pressures listed on
the table below then reassess installation pipe size or upstream regulator settings.
3)
Remove the manometer and replace inlet test point screw.
4)
Remove the operating pressure test point screw. Connect manometer tube and
measure pressure with fire running on full and with all the other gas appliances
running.
5)
Replace operating test point screw and leak test inlet and operating pressure test
points and inlet gas connection union.
