What about venting? PVC or hard metal?

I believe Takagi requires stainless steel vent pipes. When I added up the cost, the vent pipes were going to cost me more than the Takagi. I returned the Takagi and bought another model that can be vented with PVC.

They can't chew through it nor does it rust out like other screens do. It would be better if you had copper screening installed in your soffit vent. Yes, this would allow airflow still, but screen would be easier to handle than the mesh. The mesh is more intended for complicated spaces that won't take screen easily.

Plastic, but I feel that will last much longer than metal since metal tends to corrode with time.

PVC as a wire "jacket" or wrap is actually not used very often. Mostly used for very cold environments. This is some cross of rubber and plastic.

Can is be used? Yes, BUT you should use hard copper (copper rated for gas), black iron pipe inside a structure vs using a rubber hose.I can see a scenario of rats chewing thru the hose, and Poof! you're dead.I'd suggest you contact local FIRE MARSHALL, Building department, you insurance company and make sure your will and life insurance is current before using such a hose.

You would not be able to switch from intake to exhaust as the switch would be in the pvc pipe or close the vent. Unless you had a slip fit and could lift it off to reach the switch. As far as fitting it to a pvc pipe I believe it would IF you have a slip fit to the inside of the pipe. I don't think you could mount it with the pipe inside the vent tube.

Metal.....this hose was well worth the price. Kink resistant under pressure. You can easily coil hose with a little twisting to avoid kinks. Would most definitely purchase again.

to the best of my knowledge R/O water will eat away at any metal and you need to use it with pvc piping. I am NOT a plumber but if I were you I would talk to an expert.

Only typical water-line plastic (PVC) can be used on water supply lines. Venting must be stainless steel. Gas supply cannot be reduced, or unit will not work properly. It won't get enough to fire up, and maintain operation -- eventually results an error. And it is best to place unit very close to where gas line enters the house. Google search for the owner manual and read carefully - and it is best to have a professional install, as the warranty is no good if installer is not licensed in your state. Hope this helps.

We hard piped ours with pvc it wasnt hard . things did fit and it was hard to find adaptable pieces . if there is a way I could send you a couple pics. I will

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.

I used a flexible vent typically used for dryers. Not sure what size that it but pretty inexpensive.

I will go so far as to say this about PVC and steel bonding. When I was young a friend of mine introduced me to a propulsion device where steel bonded by JB Weld and PVC were used. DO apply an adequate bead. DO NOT use where heat and flame exist. DO not use on high pressure combustion devices. Long story short he lived to warn others. Yes, it bonds. Failure was caused by extreme heat and pressure.

the vent is just pipe. depending on how long a run you have you may need more pipe. You will need shut off valves for the input lines and various other fittings.

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.
