That FC9C changeout

[Adlerberts-Protege]

As per usual, I always get in a hurry and get no before pics. Here are the afters.

Now before you critique. This is a quick swap. I'm not responsible for some weird gas flex stuff on the furnace and/or water heater. I swapped the furnace, built a transition, wrapped the ducting properly, and brought the vent up to code (insulated). She is happy and I am happy to finally get this done for her.

Oh, and I know the drip leg is wrong. I fight the plumbers here all the time on it. Is what it is, I needed to get in and out on this one.

Why does the flue pipe have to be insulated? I've never heard of that before.

I have heard of needing to insulate portions of exposed outdoor pvc flues that might have the possibility of freezing up during very cold weather, but insulating the indoor portion makes zero sense to me.

A garage is not indoors.

It looks purty

Interesting. What about the secondary heat exchanger & condensate trap, and/or the drain piping? Or the entire water heater and water piping for that matter. I'm from Minnesota. Installing stuff like that in an un-conditioned space makes no sense to me. Or is that (does it need to be) a heated garage?

I do like to insulate the drain normally, but there is no external trap and it exits into a trap inside the utility room. She had it piped this way the previous 12 years in subzero temps multiple times without any issues. I will go with it. Thanks for the comments.

Is this a common place to have systems in your area? We see 80% furnaces in garages here once in a great while, but never see a water heater in a garage here. But we do see a lot of condos and apartments where they have a little room built off of the back patio or deck, door opening outside so the tenant has no access, with the furnace installed, then the darn water heater installed right in front of it. So that to change a blower, they have to remove the stupid water heater first!

We have to provide a vent on the condensate drain so pressure from the coil does not cause furnace condensate to drain slowly and trip a pressure switch. It’s not always a problem but it happens often enough that we just vent it to prevent the issue.

Your work looks good but the plumbers should be ashamed.

Well you already mentioned everything I was going to critique 😃

This was another Saturday job . I tend to not do my "best" stuff on Saturdays . System has been working well for the customer, better than that crappy York mod that was there before. POS's.
