Is the gas bottle tap fully open. Do you have isolator valves in your gas lines. They are often all grouped together fir cooker, room heater, fridge and water heater. If so is the water heater one open? Lastly it can sometimes take quite a while for gas to feed around the system if it’s nit been used for a while. I tend to light the cooker burners and oven for 5 minutes before trying to light any other appliance.

It essentially means that the gas if not igniting. Try it four or five times, but then wait for at least 15minutes before trying again (the atmosphere around the burner becomes too gas-rich for it to light). After several failed attempts, you should be able to smell gas near the outside cowling if gas is actually getting to the burner.

If it still fails to light, the burner will need further investigation.

On older installations there will usually be a domestic style switch which simply turns the heater on/off mains supply as required. The heater has a non-adjustable thermostat at around 65C. Quite often the switch is located below the settee on the side where the boiler is.

(Suggest you also read the other current thread concerning replacing a boiler)

One of the fairly regular problems I encountered with Trumastores (before they were called Ultrastorses) was the fact the burner seemed to attract insects who would make their nests in it. The same applied to Carver Cascade's also.

If they construct a nest or create any other sort of blockage, in the burners venturi or the the burner plenum, it can either prevent ignition or stop the flame from spreading properly and affect flame detection.

In the case of the Truma boilers, the burner is almost a complete circle, and the fame would burn around about 150 degrees of the circle. the missing portion is where the gas and air enters in the venturi tube. The flame would be ignited on one side of the venturi, but the flame detection was on the opposite side of the venturi, so the flame had to ignite all the way round the burner before it could be detected.

One of the characteristics that often was a symptom of this, other than poor ignition or flame detection, often the appliance would start to produce soot.

If you have any evidence of sooting, its a clear sign the appliance is need of a service. For your safety it best to leave all gas appliance service work to a professional.
