I have a Bradford White M1TW something 40gal Nat Gas Power Vent water heater. It was installed 4-5 years ago after a bad sewer back-up mucked up the burner? on the old one. It has run fine and stuff, but the other day while outside near where the vent comes out, I noticed the pipe was tweaked or twisted. It has a T on the end, and the branches on the T extend about 4-5 inches out, have screen inside. Forever I have seen the T horizontal (at least I don't remember it being otherwise) but the other day one side of the T was pointing up at around 15 degrees maybe? I twisted it back into normal place. Fresh snow, I didn't notice animal tracks or anything. Kind of let it go.
In the basement today while getting ready to tackle some plumbing and electrical out to an addition I noticed the vent pipe disconnected. It is all 3" PVC, and it was disconnected at a hub about a foot before exiting the house wall. So the straight pipe out to the T is free and hanging there. It looks to me like it wasn't ever glued. I guess my question is before I bust out the primer and cement, do I need to be worried about combustion? I don't like the sound of working with anything gas, and there's a furnace within 10 feet too. Can I prime and glue it without shutting stuff down, or should I cut power to both appliances beforehand? Thank you.

While I would prime and glue 10 ft from a flame, OSHA says 50 ft away. So I would not recommend that you would do what I would do.

Primer is category 3.

1926.152(f)(3)Category 1, 2, or 3 flammable liquids may be used only where there are no open flames or other sources of ignition within 50 feet of the operation, unless conditions warrant greater clearance.

Thank you. I will shut off power to both. This isn't exactly a basement in the 'basement' sense of the word. I would essentially be using fume-iferous things in a large enclosed closet. I got the pipe to slide into the hub for now, and hopefully my CO thingy is working.

Oh Pleeeease....give me a break..... you really cant be serious....
Unplug the heater if you are afraid of somehow setting something on fire
it aint gonna happen....

The next time I accidentally spill some glue or primer in a home I better call the fire
department just in case.......have the basement fumigated and get OSHA involved too..

Hey, wait a minute.

This is awkward, but...
