Can I use PVC for venting this unit?

No. You are better off using another brand. Takagis are not very reliable at all.

Just had one installed a month ago and NO you cannot vent with PVC pipe. You're vented super heated air and that requires a double wall metal sheet metal pipe. You also need to check the diameter of your gas line. I believe it needs a 3/4' pipe. Strongly suggest you have someone who knows what he's doing for the installation so it's at code and you don't have a disaster down the road. Once installed you'll notice a slight ebb in water pressure as the heater kicks on.that only lasts a second. It takes the same amount of time for the hot water to get to where it's going as it did with a standard tank heater but once it does you have lots of hot water Just had one installed a month ago and NO you cannot vent with PVC pipe.

If i remember correctly, a certain type of stainless steel piping had to be used for my unit installed in upstairs attic.

Hi Tony, You cannot use PVC for venting this unit. It is required stainless 4 in ventilation duct for this tankless water heater. Good luck.

It will work both ways. Vent comes set up to work inside but (in my case) I converteed it to vent outside. Easly done. H.

The paperwork that comes with this unit states it is NOT suitable for mounting as a built-in. I am guessing that this has to do with the ventilation requirements.

Yes. You can not vent inside a structure. If you were mounting outside a garage the go with this unit. INSIDE a garage you NEED and indoor unit that exhausts to the exterior thru a vent. Mounting this unit in your garage is like running you car inside with the door shut - it will kill you from the CO2.

no. This is not need for this unit. Unit mount on the outside of house and is self vented.

No. I would not because of the venting. I think they do have a model that vents to the outside. You have to be careful of carbon monoxide. Also I am sure there is a fire hazard as this unit gets hot. But outside it works great.

"&gt;&gt; ATTENTION!!! 3" or 4" PVC venting can only be used on condensing heaters (PVC adapter is built-in). - See more at: http://www.noritz.com/residential-products/nrc111dv/#sthash.QEx6SGiw.dpuf" http://www.noritz.com/residential-products/nrc111dv/ That's a quote from Noritz. Using common pvc for the vent makes the total cost HUNDREDS of dollars less than having to use stainless steel vent, or the proprietary venting of another brand. FOLLOW THE INSTALLATION INSTRUCTIONS! The Laws of Physics don't abate for the 'it ought to' crowd. PVC can ONLY be used on CONDENSING heaters. IT WILL MELT, OR WORSE, IF INSTALLED ON NON-CONDENSING HEATERS! Follow the instructions for the specific model you buy, no matter which one you choose.

Yes it can; there are ducting kits available. I purchased the unit for wall-mount and use a charcoal filter, but you can get the ducting kit as well to vent through a wall or ceiling/roof

I wouldnt use it on pvc as the amount of heat would melt the pipe. I assume you coukd keep it far away to keep the full force of the heat away from it but i wouldnt use it for that.

Yes. There are instructions on how to put in a vent. I did it and it's very easy.

It will not hurt PVC pipes. I would wrap the pipe with aluminum foil first to help spread out the heat

Sure can, just make sure the damper will open freely. If not, rip it out and make sure to get a vent cap that has a damper.MikeMbradyelectric

Yes, unfortunately. I bought this unit for an office without a window and was disappointed to find it needs to be vented, and the vent hose itself is rather obtrusive.

If it's recommended to have stainless venting use it. I did. Don't go cheap.

If you can find an adapter, you can. It may not be a good idea to shrink the size of vent since this is a powerful vent and the matched vent pipe size will fully take its max vent function. 5" vent size is kind of too small, but you can if you have no other choice.

Check your local codes. If you can use PVC for a regular water heater you can use it for a tank less system.

no but you must have 36" of copper from unit to the pvc pipe , pvc will handle the heat
