    It might help to enlighten the manufacturer that stuff is getting installed, and certain issues still need to be addressed, either with the install or the equipment itself.

    What direction would Amana consumer affairs give in this particular instance? Maybe this portion of conversation needs to be discussed somewhere other than the AOP forum.

    What's most important here is the OP got direction from the online pros here, and any danger they were in has been averted.

    Too bad the installer is not the investigative and knowledgeable type. Maybe Amana needs to be aware of this.

    If it's a single pipe system, there needs to be a combustion air supply close to the furnace. If your contractor did not install one then the system is probably pulling combustion air through your fireplace vent/chimney along with the products of combustion from the exhaust vent. Products of combustion that cause the symptoms that you described are called "aldehydes".
    Have a second contractor check for a combustion air supply and the whole system for that matter.
    You have made the right decision to shut it off until it can be certified safe.

    It would also be a good idea to check the MSDS or Material Safety Data Sheet on the mastic used to seal the return air ductwork. It could be offgassing Vocs or chemicals that cause or contribute to the problem.
    Post pictures of the installation and we can better tell you from them.

    Have you tried running the upstairs unit only and had the same symptoms?
    Don't try now, I'm just wondering if you checked each system separately and got the same problem?

    I do not know if these pictures are going to post or not. Somebody please let me know if they show up. The first picture I uploaded is the front of the fireplace. I've got press-n-seal over the vents now...yes, i'm tech savy...but they were wide open before. There are 6 round vents on the sides and then the top and bottom of the units let air in as well....I only have the bottom ones covered cause I couldn't get the stuff to stick to the top. We did not put the fireplace insert in. It was like that when we bought house 6 months ago. Next pictures show air flow when units are NOT ON. When it is on I would say the flow is stronger. Next pictures are showing the exhaust pvc on left side of picture in relation to the fireplace bottom entry box there under the deck. Following pictures show the install of unit in garage and how the pvc pipe is run through the garage and out. Contractor has not come out yet today, but he promised he would. We are in East Tennessee so it has gotten in the low 30's at night and into early mornings. I'm not sure what he has it set on to trigger but I think he said 40 on the upstairs unit. Anyway, it's safe to say the furnace runs all night and into early morning then heat pump takes over. I suffer all day in the house and it takes about 30 minutes to feel some relief from burning eyes when I am outside of the house.

    Pics showed up perfectly. I do not see a combustion air supply.
    That is most likely the biggest contributor to the problem.
    However, you are stating that you have air infiltration even with the units off? If they are completely off and the supply air blowers are not running either, then check for exhaust fans in your house that could be pulling a negative pressure on the building. If it is windy out that can also cause air infiltration, so try to check when it is calm.
    Again, get a second contractor/HVAC specialist to check it.

    When you got multiple quotes....these bubba's must have had a "fair price" .

    Whats the box with plus sign? Any reason they didn't run the combustion air too?

    I am leaning toward the fireplace isn't your problem other than being leaky. Also, more concerned about the return and the waterheater....That's a big pipe that has now been orphaned from the 80 furnace you had before.

    Give a man a capacitor, doesn't know what to do. Teach a man to install it, now he knows everything.

    You need to have someone that knows what there doing check the draft on your hot water heater.

    I would also confirm that the vent is the correct size for the water heater now that the furnace is not sharing it. There should be a new smaller flexible vent sleeved within the larger existing vent as the rigid venting has not been replaced to downsize to the proper size of the water heater alone.
    Get the second contractor to check the Tennesse Code on this.

    Yup.
    Your post had not shown up by the time I posted.
    I'm too slow at typing I guess

    I'm thinking that box with the red cross is a specialized air filter. Probably large media.
    Possibly HEPA?

    That install has serious airflow problems. Id wonder what static pressure you are running.

    Does that filter box produce any Ozone?

    anyone else think that return air drop looks a little small?

    what size is that drop and what is that "first-aid" box???

    also, the vent pipe could be undersized, that looks like a 2" PVC?

    what size furnace is that???
