8. Fault finding
Trouble
Cause
Burner does not light.
Spark is available
•
The gas valve of the gas cylinder (or gas line) is not open
•
Gas cylinder is empty
•
Air in the (new) gas lines
•
Gas injector is blocked
•
Gas pressure/gas quality is not corresponding with the data plate info
•
The burner is not on high-fire setting during ignition
•
The (optional) solenoid valve S is not connected or is damaged
•
During sparking manual ignition is possible with a lighter: check the location of
the spark gap related to the ceramic stone is correct
•
Gas safety device does not open with a
“click” during ignition period, the Ei coil
is broken. Replace.
Burner does not light.
No spark available
•
No 230 Volt available at the Ei
•
Spark electrode line is not connected to the Ei
•
Spark electrode gap incorrect. Shall be between 3-4 mm
•
Spark jumps off to other metal parts before the spark electrode. Check wire,
connectors and ignitor ceramics. Check if parts are dry
•
Ignition loop is not complete. Check the ignition wire and earthing wire
•
Ignitor Ei is broken. Replace
•
Ei is in recovery phase. Leave the Ei connected to 230V for 20 minutes to reset
and try again
Burner extinguishes after lighting
•
Keep button safety device pressed for a longer period (up till 25 seconds)
•
Position of the thermocouple is wrong (see above)
•
Thermocouple nuts are not connected properly to the gas safety device and to
the Ei unit, or the nuts are loose
•
Thermocouple is not heated by the flame or not mounted properly
•
Thermocouple switch in Ei is broken. Check (after switching 230V to the Ei) by
multi
meter if resistance of the internal switch is <25 mΩ
•
Thermocouple and/or magnetic coil of the safety device are broken.
•
Gas pressure lower than minimum requested
•
Heater not suspended at 45 degrees angle (facing downwards)
•
Not all burner stones are ignited, especially near the thermocouple
Flames:
- leave the confines of the burner
- or are sooting
- or a blue cloud is under the
reflector
•
Gas pressure is too high. Check the gas pressure with the data plate
•
Gas pressure regulator is broken
•
Wrong gas. Check data plate for the correct gas supply
•
Venturi/air inlet is blocked/dirty
•
Venturi and injector wrong. Check with the technical table
•
Not enough fresh air available due to mounting situation
•
Air filter is dirty
•
Heater not suspended at 45 degrees angle
The burner is only partly glowing
•
Wrong gas or gas pressure. Check data plate for the gas supply information
•
Injector or venturi are blocked or dirty
•
Injector and venture size are wrong. Check with the technical table
•
Pipe sizes or gas hoses have insufficient capacity
•
Setting of the thermostat is wrong
The burner makes a lot of noise
after ignition or after several
minutes
•
Wrong gas. Check data plate for the gas supply information
•
Burner stone is damaged, the flame burns inside the burner house
•
A zoom noise of the Ei is created by magnetic fields and lasts only 30 seconds.
Not harmful and temperature dependent. Turn the Ei in another position.
The burner does not work at
minimum heat input
•
Gas pressure is not correct. Check the gas pressure with the data plate
•
Wrong gas. Check data plate for the correct gas supply
•
Size of the venturi and injector is wrong. Check with the technical table
•
By-pass hole solenoid valve (S) is blocked
•
Injector (partly) blocked
•
Thermocouple has not the proper location to the ceramic burner
Heater will not attain the desired
temperature
•
The solenoid valve (S) is not functioning
•
Injector partly blocked
