Not wanting to sound patronising, I have been fitting wood burners for over a year now (5 a week approximately)
Whenever I have a burner that will not draw, I use a lot of screwed up news paper to start with and leave the door open slightly to feed the fire/paper with plenty of air. Then when the heat starts to make the fire/flue draw I add cut up cardboard then when this is going add the kindling and progress to a log when it looks ready. I also leave all the vets open until the log is really established, closing the door only when it is pulling enough to survive on the air coming through the primary and secondary air sources.
I have never had a problem lighting a stove this way and have never used firelighters to light a stove.
Give it a go and see how you get on.
