    Unless you want to provide documentation the the contrary, the venting material looks proper.
    Pipe size may be incorrect, but can't tell that from the photo.

    very few furnaces allowed the use of 1.5" pipe. Some did BUT the sharp vent elbows most certainly put it beyond the specs of 1.5" pipe.

    The elbow termination it too close to the furnace, at least for my area it is. idk about the job here, it might be normal for that area. This pic is what they do in my area. not my pic btw.

    The air box only requires the pipe be to the cabinet face before the elbow goes on and the installer did that. It matters not that part of the elbow hub is inside the cabinet. It may have been done that way for clearance issues we cannot see in the picture.

    I looked up the IOM for the Weathermaker 9200 shown. It allows for vent elbows and some models had allowances for 1 inch and 1.5 inch venting.

    Well, as I admit the picture is incorrect, do you guys get the message? Homeowners think that they can do Hvac stuff themselves, and end up messing up.

    Obviously you dont get it. You're assuming that the pic you posted is DIY. It's never been proven that it was. Plus, Ive seen some DIY that is better than some of the larger well known national companies. MANY homeowners are VERY capable of DIY. It's only that this site doesnt promote it.

    Quit while you're ahead.

    I suppose you call a plumber for a runny toilet or an electrician to change your light bulbs? And to Marc’s point I’ve done start ups on DIY mini splits and they were installed neater than I could have done, I haven’t installed more than two. The way you post things makes you come across as a know it all, not in a good way either.

    I've got a couple of 40K BTU 58MVP's in my house. They allow 1 1/2 vent for 80k BTU and under.

    60K can have up to 35' of 1 1/2" with 4=90s as an example. The install literature actually warns of using 2" if the chart recommends the 1 1/2" pipe size. It may cause "incomplete combustion, flame disturbance, or flame sense lock out."

    The 58MXA is what I looked up. It said much of the same warning-wise. Here's the clip of the 1 inch vent pipe allowance.
