| Frankly, you need a competent repairman to inspect and set up the furnace for you. The episode you describe illustrate why people are discouraged from doing their own repair work.
You took on a task well beyond your competence and exposed yourself and your family to a substantial risk of harm. That risks continues until the furnace has been properly inspected and set up.
The BTU input at which you were running the furnace was around 180,000, about double what it should have been. That not only could easily have split the heat exchangers, but very likely created a lot of carbon monoxide that, combined with a split heat exchnger, could have killed the building occupants.
So frankly, I can't help you ---- plaintiff's lawyers being what they are. The estate of whoever might be killed could be expected to go looking for as many people as possible to blame, and I don't want to put a toe in those waters lest it be cut off.
So my recommendation is to have a competent person inspect and set up the furnace. If you can't find someone willing to take the risk (I wouldn't blame them), junk the furnace and get equipment installed by someone who can do it comepetently.  |
