E2.6
Pilot ignited then
exnguished when main
burners lit.
Check gas supply and check other gas appliances to see if they are aected. If
you have two separate LPG cylinders, switch over to the full bole or contact
your gas supplier. You may need to retry igning the re a few mes aer re-
establishing gas supply.
Check regulator and burner pressure.
E2.7
Crically low supply voltage.
(<185V)
Check supply voltage.
E3.1
TCO 1 (Heat exchanger) has
gone over temperature.
Check that fan is plugged in, cleaned, and free turning - room air fan may be
slowed or stalled.
Check the burner pressure -being set too high may result in excess heat
build-up.
Check the gas jets are correct.
E3.3
TCO over current protecon
acvated.
Check that TCO wiring terminals are properly connected and not touching
the chassis or rebox.
E4.1
Primary valve solenoid
current abnormal.
Check that the connecons to each solenoid are secure and in place.
The primary solenoid on the valve inside the re may have failed. If this is the
case, the coil will need to be replaced.
E4.2
Secondary valve solenoid
drawing current when
supposed to be o.
Contact Escea technical support.
E4.3
Secondary valve solenoid
over-current protecon
acvated.
The valve solenoids have failed the pre-ignion test. A wire may have
dislodged or the valve solenoid is faulty.
Check that the connecons to each solenoid are secure and in place.
The connecons on the ends of the wires may need to be ghtened (e.g. with
a pair of pliers) to ensure a robust connecon to the valve terminal.
Check the wiring to the solenoids for damage.
E4.4
Secondary valve solenoid
drawing too much current.
E4.5
Secondary valve solenoid
drawing too lile current.
