Even I get head scratches at times, Tim Help please.
I have a Buderus G124x/32 153 KBTU boiler It is connected to a nice new chimney liner. The liner is 6" corrugated stainless in an 8"x8" clay tile. The chimney runs up the out side south wall of a ranch home to a total height above the boiler of 16'. I checked the gas pressure to the manual and it lines up fine on both sides of the gas valve. Numbers are escaping me at this moment though.
So to the problem. Twice since the liner was installed the blocked vent switch tripped and needed reset. On my second call there after the chimney company came back and said their liner was fine I removed the plug in the damper for standing pilot systems to keep the chimney pumping. So far knock on wood it is still running with out tripping. It never tripped even with me baby sitting it for over two hours and having it fire into a cold and warm chimney. Weather conditions were similar the days I was there and the days it tripped. Any feed back would be appreciated as Tech support never heard of this before and I do not like guessing on the solution. I know I am not the only guy to have this happen to. The chimney may be a red herring and I may be over looking the issue. So what do you think?
Thanks for the help.
