The Trinity replaced existing ancient hot water boiler when we bought the house in October 2006. This is old two store, 4 bedroom house, half brick. It worked fine up until December, when it shut off. The "brain" would go through various cycles, I could smell gas and air would be pumped in. All this would ended with error code (ER6) on the display. The contractor who installed it replaced igniter (Norton 601), after which the boiler worked fine. However, it started acting again two weeks ago. It shut off one evening, I noticed the water pressure was below 5psi. I let water in till the pressure was 13 psi, and the boiler came back. It did this two times. Last week it shut off again. This time i called a large local HVAC company (my contractor guy who installed and sold me the boiler does not return my phone calls any more...) and was told by HVAC tech that igniter is bad (the one that my contractor replaced in December.
So my question is why this should happen that often? Is there something wrong with boiler and /or installation that causes prematue failure of igniter? Or the sizing of the boiler was wrong? It did not seem to cycle, though... I asked this question to The HVAC tech who determined the igniter is bad, but he had no answer. All he did was he charged me $90 for checking igniter with multimeter.
In a separate question, do you think the contractor has a liability if it is determined the installation was bad? Thank you for our input.
