system 2000 leaking CO

chapchap70_2

What method did you use to determine it is leaking CO? That boiler (oil or gas) has a safety switch that turns the burner off if there is excessive back pressure so even if the burner is not tuned properly, the CO flue gases should exit the home safely or the burner shuts off (if the switch is still connected).

system 2000

has anyone had any problems with the system 2000 back cover and chamber cracking and leaking CO ? It appears the boiler had not been cleaned in a few years but I would hope that it would not be this easy to create such a serious problem. thanks arne

all the co detectors in the house went off and after the tech opened up the back of the boiler he found a hole in the large insulating panel and the fire chamber. it is an oil boiler.

Did you recently buy the house? I asked because you said something to the affect of "it seems it hasn't been cleaned in a while". I am assuming that a blockage of soot either in the boiler or chimney base caused a back pressure condition so the flue gases did not escape via the chimney (or powerventer) like normal.

I hope the tech did a thorough job fixing the problem. Did he say anything about a puff switch? I don't know of any other oil boilers that have one (codes don't require it) and this is exactly the reason for it. The switch should have shut the appliance down way before this. I have seen them disconnected though. Some techs disconnect the switch without checking the draft. (It runs without locking out so he fixed the problem, right?)

This is not a run of the mill boiler so if a tech hasn't seen it before, he'd be wise to use the manual or ask someone for help.

the puff switch was connected, unknown if it was operating properly, substantial but not total blockage in boiler flue passage

my buddy and i cleaned his boiler out the other day....

ten baggs of soot and condensation build up later.....it was running perfectly with the door open to the boiler room...i closed the door...put my carbon monoxide detector in the room ...6 ppm....can any body give me a amen for make up air suggestion?

Just take the door off its hinges:)

Great EYE Deah *~/:)

take the boiler door off the hinges Dammbit! i Knew there was a reason for all that fancy hardware on the boiler

i will have to get some duct tape to keep the burner aimed at the fire chamber ... :)here i was considering a hole to let some Oxygen into the room...foolish me.

another unique solution might be to cut a hole through the outside man door, duct tape in some of that Fancy accordian dryer vent to the boiler and put the burner outside on the lawn ...to fire into the dryer vent nah... the 1700+ degree heat from the gun might melt the stuff...back to the drawing board..:( why is there never an easy solution ...just difficult problems?

No fresh air kit

on the boiler? I think an air box and some PVC pipe to the outdoors would be the best solution

As far as I know, EK likes to see most of its boilers installed with fresh air kits.

I'm curious about the burner not locking out before the carbon monoxide detectors sounding. Even with a bad chamber and insulation board, I thought the back pressure necessary to have enough CO leaking into the home for CO alarms to sound would have tripped the puff switch.

I will find out about the puff switch, if it was installed and operating or just bypassed. It seems the tech would have caught that either way.
