Many mention re using the existing venting with this water heater. Most water heaters use 3" and this heaters requires 4". Has anydoby had issues r

The BTUs produced by the heater require that you put up the correct size of vent. If you don't, you can get a back up of exhaust in your house, cause damage to the heater, and quite possibly cause a fire. It is not that difficult to change the vent pipe. The danger out weighs the cost of replacing the flue pipe.Licensed a/c and refrigeration contractor in Texas and North Carolina.

I have only had mine installed for a few months however i would say it depends on how much it has to operate.

I don't have any issues with reducing to 3 and mine direct vents out of the side of the house, but the air that comes out is strong, but no problems after 1 year of use

Not sure. The vent is on the top of the unit and is a fixed size. Not sure if you can reduce it. The venting is a big deal with this thing--it has to be done right. If you are going right thru the wall the vent has to be pitched down otherwise you will need a way to get rid of the water that is produced while the unit is running.

This matter only has a top vent. And as far as I'm aware all water heaters never to venting. If you have space above the heater available you can put an elbow into the vent line. Use extra care on any horizontal vent runs to be sure they don't leak and slope up from the heater. Hope this helps. Ps I'm very satisfied with this heater.

The unit is designed for outdoor use. It has intake and exhaust built in. So you do not need additional venting.

Yes, it will require 3" by 5" concentric B-vent and vent cap on the outside part. These pieces are not cheap. I ordered the b-vent sections made by metal-fab from Amazon. The quality of the 3"/5" concentric vent pipes were excellent though and there is a "rubberized" gasket to seal the pipe sections. You will also need the water valves. I bought the water valves that came in a kit which ran about $78 dollars. It has the hot, cold, and release valve in the kit. I think it came with a gas valve (sorry I forget) but still had to buy some additional 3/4" black pipe to hook to the tankless water heater.

Ours works fine, but our builder did not allow enough room to vent out the heat it generates (it's built in). We tried to remedy ourselves, but it needs a professional to correct the issue, so it sits unused. Sorry I spent the money.

Not certain this item is good for your application. Try to see if Fantech has a fan that has a three inch opening. Also, measure your vent length to determine if this model is the right one for your application. Finally, you may be able to change the vent size. If not there is an adapter piece that fits onto the three inch vent to adapt the opening to accept a four inch vent pipe. Obviously you have several choices ahead of you, good luck.

If your water heater anode fitting is 3/4" NPT threads then it should work. Also if the new anode is too long then you can just cut some off of the end with a hack saw like I did to get the length you need. Hope this helps.

John, I believe that the stove pipe is 3 inch round, vent pipe for gas water heaters is 3 1/2 inch round, you can size that down, I have also read that you can get an exhaust pipe such as they use on tractor trailers, and have a machine shop shape it to fit your needs.

no you will need to purchase the 6 inch duct and roof vent. This unit is very good and super quite. you can hardly hear the exhaust fan and the heater does a very good job of heating the bathroom

It depends on the model number identified in your manual. I could not locate a manual for your water heater. The screw size is the same but the length matters!!!

Felickz, I guess I misspoke about the size of the vent piping size, Which this fan does vent 6". I also recommended using the Broan 636 fan-jack but meant to use the Broan 634 fan-jack for roof installation or if venting sidewall use the Broan 843 which both have a back draft dampers. Hope this clears this up!!!MarkInnovative HVAC Systems, Inc.

Minimum size gas line is 3/4". The one I bought came with the shut off valves for the gas and water, but some don't. None of them come with the vent cap and special double wall 5" exhaust duck. It isn't required but you should consider a good drip pan since it does not come with one. It needs electricity. It has a 110V cord/plug, but you have to have an outlet to plug it into. It comes with the remote mounted controller, but it only has about 10' of cord. If you are mounting this in an attic and mounting the control panel down on the main floor you will most likely have to buy some more thermostat cord. It is readily available at any home improvement center and is cheap. Minimum size gas line is 3/4". The one I bought came with the shut off valves for the gas and water, but some don't.

3/4" should be just fine, it is not up to code, and you will get less than the listed power, but it will work fine to replace an 80 gal storage tank.It takes 52K BTU to heat 80 gallons by 77 degrees, with a 70% efficient water heater. With a 'first hour' rating of 120 gallons it is 78K BTUYou can get 79K BTU at the end of 100' of 3/4" pipe (or equal, with fittings). Code for this heater would require 1" for a run of more than 10'As a note, the efficiency listed is a best case running full power.

Best advice is contact a plumber. In my area the plumber told me it had to vent out an exterior wall according to our building code. They couldn't use my existing vent.

I had the same issue on the exposed side of the Sheet Rock/Plasterboard, what I did was to go inside the wall and in my house it was 3/4 inch pipe and I plumbed it to 3/4 to the water heater. I am telling you what I did, I am not instructing you to modify your gas lines, Natural gas is explosive.

It calls for 3/4" gas line to the heater. Everything you need is not with the heater. My husband called Rheem about the exhaust pipes & vent and the gentleman gave him prices on it and suggested he shop around for a better price. As it turned out, the better price was on Amazon! It does have to be vented outdoors.
