Boilers
Normal Operation
During normal operation the digital display will dhow the current boiler temperature and will
show a "." In the lower right corner of the display when the burner is alight. If the green lamp
near the CH or DHW+ - keys is illuminated the boiler is receiving a demand for that function.
If the green lamp is flashing the boiler is either up to temperature or shutting down following
removal of the CH or DHW demand.
Fault Modes
In the event that the boiler detects a situation which it considers to be a fault the display will
change to show a flashing fault code starting with an "E" and then a two digit number. The
table below explains these codes and the action you should take.
Display
Description of fault
E01
Ignition failure - the boiler has attempted to light five times and not succeeded - check
the gas supply is on.
E02
False flame - There is possibly a problem with the power supply.
E03
Boiler overheat - Check that any valves to the heating circuit have not been shut down,
that there is no air in the system and that the water pressure is correct..
E24
Water pressure losses - You have topped up the water pressure more than 4 times in
24 hours. You may have a leak on the system..
E26
Flame drop out - Check for obstruction of the flue and/or air terminals,
blockage/freezing of the drain pipe or a low gas supply (LPG).
E34
Mains supply voltage < 180V - There may be a problem with your power supply
E35
Mains supply frequency incorrect - There may be a problem with your power supply.
E37
Water pressure error - You must top up the water pressure for your system
E40
Water pressure too high - You have put too much water pressure in your system
The above is an abbreviate list of possible error codes. If the code is not in the list above
consult a GAS SAFE REGISTER registered engineer. A full list of codes can be found in
Chapter 6 of this manual. If a code appears and you feel the original cause has been rectified,
press the "Reset" button to resume boiler operation. If the code persists consult a GAS SAFE
REGISTER registered engineer.
When topping up the water pressure you can observe the actual pressure by pressing the
"Installer" button repeatedly until the number "5" appears. After a few seconds the display with
then change to show the system water pressure in bar. Set the water pressure to between 1.0
and 2.0 bar.
Precautions
Care must be taken at all times to ensure that no blockage or obstruction is present in the
condensate drainage line. In addition, the air intake and flue exhaust terminals must be free
from obstruction at all times.
Frost Protection
The C36 Combi has an integral frost protection function. However, care should also be taken
that any exposed pipework is adequately insulated to prevent freezing.
