Do you have one or two plastic pipes going outside? If two, one is exhaust and one is inlet combustion air. Check to make sure neither are plugged or froze up outside

Do you mean like a boom sound lighting and turning off? If it makes a puff boom kind of sound when igniting it is most likely your heat exchanger is cracked.
