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 at the wall then on again.
The following table shows what each code means and possible ways to rectify the situation.
In the case of persistent or repeated shutdown errors, action must be taken immediately to find
and repair the fault.
Error Code Suggested action
PCB Over Temp
(Printed Circuit Board)
-Usually insufficient cavity ventilation.
- Possibly outer fascia panel installed incorrectly.
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
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 propane 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 and that they have the correct air gap. Check that the spark
electrode is positioned in front of a port in the front burner.
- 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.
OR
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.

Draught Diverter
Bimetallic Trip
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).
Valve Solenoid
Check Failure
The valve solenoids have failed the pre-ignition test. This is to detect a
faulty valve solenoid. However, it is possible that some of the wiring
connections between the resistors and the solenoids are not secure, or a
wire has dislodged. Check that the connections to each solenoid and
resistor are secure and in place. It may be that the connections on the
ends of the wires need to be tightened a little (eg with a pair of pliers) to
ensure a robust connection to the valve or resistor terminal.
It could also be that one of the solenoids on the valve inside the fire have
failed. If this is the case the valve will need to be replaced.
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. Ensure there is power to the
fire by pressing the auxiliary on/off (red) button on the fire, then press the
on/off button on the remote to clear the error.
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 the 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. These sensors must not
be disabled or bypassed.
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 Fascia, Log Set and Glass:
NEVER RUB THE FASCIA. The outside of the fascias must only be cleaned with a clean
damp cloth, dry off after cleaning. 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 black smudge that cannot be removed. Always clean when cold.
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
or that there are no adverse environmental
conditions inhibiting clean combustion.
Step 1: Lift off the inner fascia by removing
the screws attaching the bottom of
the fascia to the firebox and 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: Clean the inside and outside of glass with
normal glass cleaning products. Use a
CLEAN DRY cloth to remove cleaner
residue. Stubborn marks may be cleaned
with a ceramic glass cleaner.
Step 5: 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 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 for IB850 and two burners for IB1100 are
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 for IB850 and two
burners for IB1100 are running).
4) The heater regulator pressure has been factory set to 0.87kPa for Natural Gas heaters
and 2.30Kpa for LPG (PROPANE) 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 Drawer
ISOLATE THE POWER TO THE FIRE BEFORE PROCEDURE.
All of the electronic components of the heater have been located on a removable drawer.
This drawer is located on the left hand outer side of the IB850 and IB1100. On the back of the
drawer are two large connectors that unplug as the drawer is removed so only the three wires
connecting the electronics to the ignition and flame rods must be removed manually from the
PCB (Printed Circuit Board).
Step one: Remove outer fascia by taking out two screws located behind the bottom fascia trim
panel.
Step Two:
Take out the two screws at each end of the
electronic drawer and pull drawer 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. Press the – (minus), + (plus) and the Fan Boost buttons simultaneously
until all the characters on the display light up. This will put the remote into
test mode and the two large temperature digits should be reading 00.
3. Press and hold the – (minus) button until the two large temperature digits
reading 00 start to flash slowly. Release the – (minus) button. The remote
control is now ready to be addressed to the fire.
4. Press and hold the red auxiliary on/off button on
the fireplace for a minimum of eight seconds, or until
the two large temperature digits start counting
upwards from 00 to 99 repeatedly.
Note: Pressing the red auxiliary button on/off button will start the fire. Once the remote control is
counting the fire can be turned off by pressing the red auxiliary button again.
5. Press the large power button in the middle of the remote control to exit the test mode and
return to normal operation. The remote should only be displaying the time. Check the fire will
start using the remote control by pressing the large power button. Turn it off again using the
remote control.
6. The fire is now re-addressed to the remote control.
