Whenever this boiler starts after a long off and cold, below 130F, it has to cycle at least a few times before the flame stays on. Before the post-fire purge stage can finish, the flame goes out and a new cycle starts immediately. It just keeps repeating such sequence for more than 5 cycles until it warms up and then rapid cycling stops and the flame keeps on until its first high limit.
In the meantime, at least 5-6 mins have gone by and only then high limit temp. can be reached for the first time. Is this normal? It does not look very efficient, does it?
