Error Codes:
This gas fire has been designed to show error codes to help explain and identify any fault
situation that occurs.
These codes will appear on the wireless control in the form of a large letter “E” with a number
beside it. Codes can normally be reset by turning the heater off then on again at the wall.
The following table shows what each code means and possible ways to rectify the situation.
Error Code Suggested action
PCB Over Temp
(Printed Circuit Board)
IB600 - Usually associated with a four sided fascia being mounted too
high resulting in an insufficient air gap between the lower removable strip
and the bottom of the outer fascia.
IB850 - Usually insufficient cavity ventilation. Note: This error has a
permanent lock out and will require the unit to be reset 10 minutes after
the initial error (turning the power to the fire off "at the wall" then on again
after a few seconds).
Flame Failure or
Power Flue trip
The fire has tried to light three times and failed.
- Check gas supply and check other gas appliances to see if they are
affected. If you have two separate LPG cylinders, switch over to the full
bottle or contact your gas supplier. You may need to retry igniting the fire
a few times after re-establishing gas supply.
- Check the electrode placement in relation to the flame. Ensure it is well
enveloped in flame as per the diagram in the installation instructions.
Ensure no coals have dropped onto the ignition electrodes between the
burners.
- Ensure the electrodes are not contacting any metalwork including the
burners.
- Check that there has not been a significant reduction in pressure inside
the house (such as an extractor fan in a nearby kitchen) which can pull
flue gas back down through the firebox "snuffing" the flames.
Draught Diverter
Bimetallic Trip
The bimetallic snap disk mounted on the hood of the draught diverter at
the rear of the fire or on the lid of the fire has tripped. The possible causes
for this could include... A gust of wind pushing exhaust gases back down
the flue or a significant reduction in air pressure inside the house or cavity
which is pulling exhaust gases back down the flue (such as a extractor fan
in a nearby kitchen).
If installed into a tight masonry cavity it may indicate that the whole
installation is getting too hot and some additional ventilation into the cavity
may be required.
In the unlikely event that the fans have stalled, and the snap disk on the
lid of the fire has tripped, this would show an E3 also. Simply check that
the fans are running normally after resetting and running the fire again.
Note: This error has a permanent lock out and will require the unit to be reset 10 minutes
after the initial error (turning the power to the fire off "at the wall" then on again after a
few seconds).

Remote cannot
communicate with
fire
The remote cannot communicate with the fire. Reasons for this could
include the fire being off "at the wall" i.e. a loss of power to the fire or the
remote is outside of its effective radio frequency range (too far away from
the fire). Typical Remote range is 1m to 12m.
Draught Diverter
Temp Sensor Trip
The draught diverter temperature sensor has detected that the air
temperature at its outlet has exceeded its maximum limit. This would
indicate similar conditions to the E3 error above.
Note: This error has a permanent lock out and will require the unit to be reset 10 minutes
after the initial error (turning the power to the fire off "at the wall" then on again after a
few seconds).
Valve Temp Sensor
Trip
The valve temperature sensor has detected abnormally high temperatures
around the valves. This is an unlikely fault and should it occur please
contact that Escea agent you purchased the fire from.
Note: This error has a permanent lock out and will require the unit to be reset 10 minutes
after the initial error (turning the power to the fire off "at the wall" then on again after a
few seconds).
Temp Sensor Error
This indicates a fault with one of the two temperature sensors installed in
your fire. Resetting the fire (turning the power to the fire off then on again
after a few seconds) and if the fault reappears, please contact your Escea
sales agent to organise a replacement sensor.
Note: This error has a permanent lock out and will require the unit to be reset 10 minutes
after the initial error (turning the power to the fire off "at the wall" then on again after a
few seconds).

Cleaning the log set and glass:
NEVER EVER RUB THE FASCIA
The outside of the fascias must only be cleaned with a damp cloth. The high temp silver
powder coating that is used on Escea fascia parts contains certain amounts of aluminium
that when rubbed too hard will oxidise leaving a big black smudge that cannot be
removed.
This is a service procedure that will need to be carried out when ever soot builds up on logs
and/or inside of glass.
If soot build up becomes excessive or regular then one of the following actions may be required;
•Reset gas pressure, pressure may be too high;
•Reposition log set so that front edge of each log is just behind each row of holes in burner
top;
•Clear any blockage from primary air port of burner;
•Check to make sure flue system is drawing well.
Step 1: Lift off the inner fascia by unscrewing the
two screws situated underneath. pull
the base of inner fascia out by
lifting it up and off.
Step 2: Unscrew the top glass
retainer and remove it. Take
care that the glass does
not fall forwards at this
stage.
Step 3: Lift out glass and place it carefully
aside.
Step 4: Take out log set and gently brush any
soot from log with a soft hearth brush.
The burner tops can be vacuumed to
remove any excess material.
Step 5: Clean the inside and outside of glass with
normal glass cleaning products. use a CLEAN
DRY cloth only. Stubborn marks may be cleaned
with a ceramic glass cleaner.

Step 6: Replace in opposite order and test run heater.
Checking Operating Pressure:
This is done at the regulator located at the front RH 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 heater on full (all three burners running) and measure inlet pressure. 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. Replace inlet
test point screw.
3) Remove the operating pressure test point screw. Connect manometer tube and
measure pressure with heater running on full (all three burners running).
4) The heater regulator pressure has been factory set to 0.87KPa for Natural Gas
heaters and 2.30Kpa for LPG heaters. Please check that the operating pressure is
exactly as listed and if not, adjust screw in centre of regulator until pressure is correct.
5) Replace operating test point screw and leak test both test points.

Replacing Electronic Draw
All of the electronic components of the heater have been located on a removable draw.
This draw is located on the left hand outer side of the IB850 and under the front burner of the
IB600. On the back of the draw are two large connectors that unplug as the draw is removed so
only the three wires connecting the electronics to the igniters and flame rod must be removed
manually from the PCB (Printed Circuit Board).
ISOLATE THE POWER TO THE FIRE BEFORE PROCEEDURE.
Step Two:
Take out the two screws at each end of the electronic draw and pull draw directly outwards
Step Three:
Carefully remove the two wires shown
from the white ignition module.

Replacing a wireless control:
If the wireless control becomes lost or damaged, a new one can be ordered from any Escea
retail agent.
When you have the new remote, the following procedure needs to be followed to “teach” the
remote to only communicate with that fire.
1. Ensure the fire and remote are set to “Off” (only the time is displayed on the remote).
2. Turn on the fire using the Aux On/Off (red) button on the front of the fire under the removable
bottom front panel.
3. Wait 1 ½ minutes until the fan begins to operate, wait a further 15 seconds and then press
and hold the auxiliary On/Off button for no less than 8 seconds (Note: This will also extinguish
the fire).
4. Immediately after releasing the Aux On/Off button turn on the remote control and wait four to
five minutes. During this time the fire will re-ignite.
NOTE: During this period the fire will listen for any coded remote signal and re-address itself to
this new code. So make sure the batteries of any other Escea remote that may be nearby are
removed.
5. The fire is now re-addressed to the new remote control.
Gas Type Conversion
Gas type conversion kits can be ordered from your Escea retailer under the following part
numbers;
NG-850 Natural Gas Conversion Kit - IB850
LPG-850 LPG Conversion Kit - IB850
