looking for someone to service Quantum Q90 boiler, his posting was attached to an old posting so it would not get much attention here it is:

Dunkirk Q90-100 Short Cycling

I have a Q90-100 that is shutting off after reaching 120 degrees. I disconnected the air intake going outside, and now it shuts off after reaching about 150 degrees. The Boiler Control (IBC) is brand new. Igniter is about a year old. When it shuts down the power light on the IBC stays on, so it can't be the casting temperature safety switch. I've set the High limit Aquastat to 200 degrees instead of 180, but this did not work either. I've ruled out simple problems like the room thermostat.

I'm looking for a technician in the New York City area familiar with the Quantum series gas boiler. This may seem like a simple request, but in the 10 years I've had this boiler it's never run right no matter how many service people came to look at it.
