I posted a few days ago on relocating my HW heater to make more
space in my basement. I purchased a Kenmore (AO Smith) HW heater on
Friday and today I started piping the gas. It was a lot easier for me
to come off the Tee for my furnace than to use the existing gas line,
which will eventually be capped off and enclosed in the wall. You
can't see it in these pics, but the old gas drop is actually more to
the right of the old HW heater. Plus this also let me keep the old HW
heater runnning while I work on the new one. Here are some pics:
Is there anything wrong doing it like this?
The other problem is that you should have a licensed plumber check your work for
code compliance or you will have a problem when it comes time to sell the house.
I'd be concerned that you have a large enough supply to run both the furnace and
HW heater at the same time.
I looks like mine is hooked up and lots of other ones I've seen. The
thing that might cause someone to look twice at it is the extra long
extending down just before the gas heater. Normally that stub is
Mostly, but if it is not possible to use a hanger, it is allowed to use a
floor support. Given that a ceiling or joist can be 16' above a gas line
while the floor is 10" below, sometimes it just makes sense to put a cradle
Should not be a problem since that is what I had originally. The pipe
running across the ceiling is 1", then there is a 1"X3/4"X3/4" Tee.
One 3/4" drop comes by the furnace (which then Tee's to 1/2" to feed
the furnace). The other 3/4" went on to feed the old HW heater/dryer/
What I did was add another 3/4" tee by the furnace drop. Plus I am
eliminating the old HW heater.
So I'm not changing the size of pipe or adding on something else. The
volume of gas stays the same.
At first I thought you were joking, but on second reading I can see
you're not. The draft hood comes standard already attached to the WH
around here. Yours doesn't?
My CodeCheck has the applicable requirements listed this way in the
Water Heaters section:
Draft hood/barometric damper in the same space as WH
IRC [1802.1, 2407.3] UBC
Only 1 draft hood
IRC [2426.5] UBC
Secure vent connector to draft hood & vent with screws or other
IRC [2427.10.7] UBC
And some more on it:
I live fairly close to the OP and our Town allows a homeowner to do
their own plumbing work if they take a Town test and pass it. We are
not allowed to work on gas lines or electrical. Both of these are
ignored on a daily basis, as is the requirement for getting a permit
and having inspections.
Ok here is the finished product. Just got this bad boy hooked up
Yes, there was no draft hood on the existing HW heater. I don't know
why they did it like that, but this is why I refuse to have anyone do
work in my house. I replaced the flue going into the chimney as it was
rusted and corroded.
I even added an extra shut-off valve on the HW outlet just for
I took a nice hot shower, had my pasta dinner that my wife made with
sausage and meatballs, and now I'm having a glass of wine and getting
ready for the Jets/Pittsburgh game.
