With help from a previous owner I managed to get my Taylors drip feed 79D heater going. The original problem was the thermocouple had been dislodged.
The heater now lights but I am less than impressed with the heat output. I certainly do not get the internal burner glowing, which is what I was told to expect.
The drips are steady, 2 per second-ish.
A pointer might be that the flame (yellow) seems to be in the bottom of the combustion chamber. Should I expect a blue flame?
The flue is more than a metre long.
Any ideas before I strip-down and de-coke?
