SSI heat exchanger warning Options

I posted this last year, heating season is here again. These are big cracks, a tiny one you would not be able to hear would still be dangerous. These are not accident damaged. If you have a set on your car, grab the carbon monoxide detector from home and take a ride with the heat on and windows rolled up. There is a detector used in small aircraft also available. The last photo is how we now test for leaks using air pressure. Brad

my first encounter with a sshe that had a crack in the pipe within the tin area. during my test, one pipe out of four clearly had some air bypass. i cut the tin off and basically the air was escaping thru basically a pin hole along a fissure. as you can see this crack is minor compared to brad's examples. thanks to brad for pointing out the potential for this occurance and his testing proceedure.

here is a link to some info on COHb levels as read by the kiddie night hawk detector shown in a post below.

as you can see, I plug on end and tape around the head end as to have a clean surface to put my mouth on, so I can blow orally to check for leaks, works fine.
