Question

Removing old water heater vent


Here is what it looks like in the attic.

The water heater is relocated, now I am thinking of using the roof opening for a bathroom vent.

What would it take to remove this?

Could be asbestos, so I need to take the appropriate precautions.

Pretty sure this is asbestos! Use caution! Am a Journeyman Sheet metal worker and see lots of this! Asbestos only dangerous if Airborn, you can soak it down before cutting to stop it from getting into the air. (or as i prefer - Hire someone to remove it) As for changing it over once chimney is removed - Very easy. Use exsisting roof flashing, purchase C-vent (snaplock) in size to fit as snug as possble. you will also need new raincap and storm collar in that size. Pipe to fan with C-vent and insulate. If u need to reduce size from flashing size to fan outlet size, purchase a pipe increaser 4"->6" and do so inside attic. Also if fan is to be mounted so that the housing of fan goes into the attic you will need to get a Vapor Barrier boot to go over top of fan and tie it into exisiting vapor barrier above drywall and under roof truss.

The water heater was in a closet in the laundry room. Inside the closet it has been patched over.

The round patch is where the vent was.

Ok. It looks like asbestos paper/insulation on the pipe. As above, wetting it keeps it from becoming air born. The you can remove it.

I don't believe there should be any cutting involved. I think I can get it dislodged at the bottom and then pull it out through the roof. I will have to get someone to help me on this.

I'm not sure what sort of information you're looking for on C-vent. C-vent is heavy gauge, single wall venting that can be used as a vent connector only. It requires 6" clearance from combustibles. If you're planning on doing any gas appliance venting of your own, stick to b-vent for both the vent and the vent connector(s).
