Perel FT10C Bedienungsanleitung Seite 9

The appliance can be checked for soundness as below. A gas test gauge and gas leak detector spray is
required.
Step 1 - Connect gas test gauge to gas meter.
Connect a zeroed gas test gauge to the testing point of your gas meter.
Step 2 - Open supply valve.
Open the supply valve of the meter until the pressure increases to approximately 10 mbar.
Then, close the valve.
Step 3 - Observe gas test gauge.
Wait for 1 minute and observe the gas test gauge. There should not be any perceptible
movement of the water in the u-tube. If the pressure rises, it demonstrates that the supply
valve is not fully stopping the gas from leaving the meter; it is 'letting-by'. The valve will
need to be checked further. You should spray leak detection spray into the valve to double-
check if it is letting-by. Gas let-by will be indicated by bubbles forming around the supply
valve. If a leak is detected, the supply valve should be repaired or replaced by a qualified gas
safe engineer.
Step 4 - Increase pressure.
If, however, there is no let-by, slowly open the supply valve and increase the pressure until
the gas test gauge reads 20 mbar. Then, close the valve.
Step 5 - Wait for another minute.
Allow another minute for temperature stabilization. This is a period of time in which the gas
expands or contracts and adapts to the temperature environment within the pipework.
Following 1 minute, if the pressure has dropped slightly, readjust the pressure to 20 mbar by
opening the supply valve.
Step 6 - Observe gas test gauge.
Observe the gas test gauge over the next two minutes. During this time, there should be no
pressure drop. If a drop has occurred, close the appliance isolation valves on the meter to
confirm that the meter itself is not leaking and the drop is, instead, due to a faulty gas
appliance. No drop is allowed in the system pipework if the isolation valves are closed.
Step 7 - Remove gauge and reseal gas test point.
Following a successful test, remove the gas test gauge and reseal the gas test point on the
meter.
Re-open the inlet supply valve and apply leak detector spray to the test point and all
pipework before the valve to the supply pipe to double check that there is no leak.
Never leave the heater unattended while burning.
Troubleshooting
problem
The piezo igniter does not work.
No gas.
The burner switches on but the
flame dies out when releasing the
gas valve button.
V. 05 – 04/07/2018
FT10C/FT15C/FT30C
possible cause
Damaged piezo igniter or
electrode.
No or loose connection between
electrode and piezo igniter.
Clogged nozzle.
Damaged solenoid valve.
Damaged thermocouple and/or
thermo-element.
9
possible solution
Check the piezo igniter and
electrodes, and replace the
damaged part if necessary.
Check the connection and repair if
necessary.
Carefully clean the nozzle with
pressurized air. Never use a
needle or similar pointed object.
Replace the solenoid valve.
Check the thermocouple and
thermo-element, and replace the
damaged part if necessary.
