Action
•
Check if gas valve of the gas cylinder or gas line is open
•
Check if gas cylinder is empty
•
First ignition will take up to 60 or more seconds before gas is available
•
Check if the injector is blocked
•
Check if the gas pressure/gas quality is identical to the pressure
indicated on the data plate
•
Keep button safety device pressed for a longer period (up till 25
seconds)
•
Check if the thermocouple is connected properly to the gas safety
device
•
Check if the thermocouple tip is 8mm under the bottom plate (27 or 28)
Thermocouple or magnetic coil of the safety device is broken.
•
Gas pressure lower than minimum requested
•
Heater not suspended at 15 degrees angle
•
Gas pressure is too high. Check the gas pressure with the data
plate
Check if the gas pressure regulator is broken.
•
Wrong gas is used. Check data plate for the correct gas supply
•
Venturi/air inlet is blocked/dirty
•
Valve dual injection model DI is leaking
•
Check the size of the venturi and injector with the table
•

•
Check if pipe sizes or gas hoses have sufficient capacity
•
Check the setting of the thermostat
•
Valve dual injection model DI is blocked
•
Wrong gas is used. Check data plate with the gas supply
•
Check if the inner globe is broken or damaged so the flame burns
inside the venturi tube
•
Gas pressure is not correct. Check the gas pressure with the data plate
•
Wrong gas is used. Check data plate for the correct gas supply
•
Check the size of the venturi and injector with the table
•
Sensor or wire thermostat TH is broken
•
Thermostat TH valve adjusting mechanism is blocked
•
By-pass hole thermostat TH or solenoid valve MK is blocked
•
Injector (partly) blocked
•
Centre hole dual injector DI is blocked
•
Check if the thermocouple tip is 8mm under the bottom plate (27 or 28)
•
There is insufficient heat in the building for heat loss (i.e., not enough
brooders).
•
The thermostat TH sensing bulb is incorrectly placed
•
The thermostat TH is out of calibration or broken
•
