i have an ideal responce 120 boiler whenever the heating or hot water is turned on the boiler lights but then goes out about 2 seconds later and lights up again then goes out and does not stay lit, and each time it lights their is a loud woof kind of noise how can i fix this

poss flame rectification problem, woof noise could be just the ignition if really loud poss ignition prob i.e spark probs not sparking in right place or over gased this could also cause the boiler to shut down and re try to light could be 1 of 3 problems without seeing it
