    Don't diy

    Customer installed a furnace that they bought From home depot I guess. It wouldn't do anything, they couldn't figure it out, they call me.
    So I find a neutral wire was not in a wire but. Now the furnace turns on, but fuse blows immediately. Cool. Find the old two wire tstat wire was clamped so tight that the coating sheered so it was grounded on the furnace. Get that handled and now the furnace lights, blower tries to turn but the fan wheel is grinding on the housing and needs aligned. Now we start up and the fan turns on, and I hear in the drastically undersized and poorly installed return ducting- bing, bang, boom. Open the filter access, and a dogs ball made it down the trunk, past the filter, and fortunately was stopped by the furnaces metal.
    So the filter is wrongly sized so much a rubber ball can get through, nevermind about dust
    5 ton furnace I believe, 110k btu and the return has 4 six inch rounds supplying it, and (if you can see in the pictures) is cut into the back of the furnace (I've never seen a manufacturer allow this), and the opening is roughly 8x12
    The vent looks awfull. I'm not sure how they got away with it but somehow there's a tag of approval from the city on they're water heater they put in at the same time. Look at the pics and tell me, that flexy crap (is that legal for appliance venting??) Is definitely not 6" from combustibles, and not only that, we have roughly 160k btus going into that tiny oval asbestos chimney? How did they get away with that?
    Oh and he didn't understand why I had to charge money.. "it's a brand new furnace!"... Uh ya, I didn't put it in bud, just cuz it's new doesn't mean I give away free work

    Gah. The 2nd pic didn't come through for me. Im betting its the top of the water heater. Its pretty bad. As much as I want to say I would only replace not repair.. i would want to see it work properly just to say all this... was wrong.
    About the only thing I've seen worse was a 4ton 100k horizontal with a 14" cut into the bottom shoved in until the duct touched the blower and had all 6 in ducts. Fed from a 6" trunk line.. 1-6" take off.

    I thought I took a pic of the wh but I guess not, you can see most of its venting though.
    It's brand new like the day was this week with city tag on it, which means somehow they passed inspection...

    That asbestos oval ir really special. Just where does it go to?
    Is that the "chimney"?
    United Technologies should be so proud.
    It`s better to be silent and thought the fool; than speak and remove all doubt.

    I might have just red tagged it and walked away.

    Was a combustion analysis performed to keep them from dying after you left? Common venting an 80% furnace with a natural draft water heater has an enormous risk of spilling at the draft hood.

    Other than the tee connection and transite pipe i don't see an issue with the venting? It is a listed connector i believe.
    Of course the back return and electrical connection is terrible

    If I'm not mistaken that flexvent is considered b-vent... we don't use it. Matter of fact I have rarely seen it. Its the unicorn of venting... the box stores sell it but none of my suppliers do.

    That flex pictured appears to be B-vent, judging by its connections.
