We had to buy special pipes for the venting to work. If you call a local distributor (Rinnai) they can give you more details.

Just the vent kit. Everything else you can get locally from the hardware store. The manual is available online and is really good at explaining the installation.

You will need to buy the exhaust pipe made for that tankless water heater. You won't be able to use the existing one

You need to have your water checked, sometimes, depending on the quality of the water (well water for example), you might need a softener or purifier. Most municipal water won't need these extras. You will also need a venting system if the unit is inside.

There are too many variables to really answer that accurately. How often and how long are your showers? Bath tub or just showers? Do you have a dishwasher? What temperature setting will you have on it? How long is the hot water pipe run to your furthest appliance, etc. I have a large tank with generator, fireplace and the hot water heater. I fill it up once per year unless the generator runs due to a power outage. The Rinnai is quite efficient, but I would recommend you go with at least a 30lb tank and have another full tank on stand by until you learn your usage.

When I purchased my unit there were both LPG & natural gas units available. I initially ordered the LPG model and very soon saw that it would require constant trips to buy refills and they would cost a ton more than using natural gas, which I use to heat my home so I returned it for the unit shown. I know that the LPG model could not be converted to natural gas. I have no knowledge either way of conversion from natural gas to LPG for this unit. I am sure that Kozy World customer service could tell you what options are available.

just need a BBQ type reg and hose, or borrow the one off your BBQ. I bought one at the local Ace hardware, but Home Depot carries them too. Walmart might also. Camping goods places, Walmart, Sports authority, Camping world , will have ways to do multiple hookups. so one tank will do several things. Remember it takes propane, not natural gas.And you have to adjust the air to get a pretty blue flame with the bolt that fits in the burner.

If it is dual fuel you will need a 220 electrical line and a natural gas line... no 110 needed if you need the 220.

Natural gas would come from a line you have in your house from the utility company.and if you don't have a line in the house,you would have to use a propane heater and the tank is supplied by the propane company.

More important than how big your home is would be how close is the tankless heater to your point of use and how cold is the incoming water? I live in Florida, so the water is never very cold which helps the heater to work very well for me. If your incoming water is colder than 55*F, I would recommend a bigger unit than the N120.

The Rheem RTGH-95DVLN is natural gas while the RTGH-95DVLP is propane. The two are comparable, they just use different fuels. We have the natural gas model, which has been in our home for a little over two years, and we love it. If you are seriously looking then I think the propane unit should be high on your list.

I would call Rinnia. They are really good to work with. I would guess that you are putting too much demand (too many fixtures on at the same time) or your gas supply isn't adequate. There are a bunch of factors involved there. Pressure, size of the line, distance of the run other appliances using the supply before it gets to the on demand unit.

My husband is in the process of getting this hooked up. We purchased the transfer switch so it is a little more involved. Our hope was to run a hook up from our 500 gal tank but some of his coworkers (hospital maintenance workers) said there could be an issue with pressure from our large home propane tank so they referred him to our propane supplier. You might want to call your company and speak with an expert. We haven't made the call yet.

You cannot buy a natural gas tank. Natural gas is supplied to your home. You're thinking of propane?

I am a certified Rinnai technician. It is not recommended to us such a small cylinder on the R94, or any other on demand water heater. That said, a 20# cylinder holds about 4 gallons of LP gas. I've installations with a five person household that use about 12 gallons per month. The issue is not with the holding capacity of the cylinder, but with the vaporization capacity. I would suggest using a 100# cylinder which is available at Home Depot or Lowes. That will give you approximately 25 gallons of storage, and it will vaporize sufficiently to maintain adequate pressure. Hope this helps Additionally, the piping to the heater from the second stage regulator must be able to handle the gas flow properly. Rinnai specs a 3/4 inch line (iron pipe or csst) from the regulator to the inlet of the water heater.

The Rinnai model RL94iN includes a set of valves with the water heater. Unfortunately, the Amazon description does not indicate that point. As a result, I purchased a set of valves separately, and had to return it later for a less than full refund. The water heater is very particular and sensitive to the type of exhaust pipes used. You cannot merely connect it to an old existing double wall system used by the water heater being replaced. Otherwise you get an error code, and the system will not operate. Check your manual.

I am no pro but I am a "handy" female and I installed one this weekend. Mounting was so easy it should not be a worry and The outside Tankless heater does not need venting so that was a big plus for me. There are Three things you must check you have before you start: #1 Must have 3/4 inch gas line (check for your model) for this model. I upgraded mine by replacing the T at the main pipe (Tankless needs the capacity so no cheating by using a reducer to size up from smaller capacity). #2 Must Get the Tankless Water Heater Service Valve Kit or you will not be able to service/clean it and save yourself heartache (it will break easier than standard HW heaters if not serviced regularly) I got mine at HD. #3 Needs 110 v electricity (I put in a light switch outside and put outside cover over it so we could turn it on/off as needed). One thing everyone should be aware of that can be a gotcha: There is a sensor which will not allow the unit start until all gas/water/electricity are hooked up and if you do try to start it before then (such as when trying to test the electricity to the thermostat like me), their is a sensor that will not allow it to start until everything is hooked up. The thermostat may not come on after doing this. It needed to be reset by turning the electricity to it on and off; I just used the GFI on the outlet on this electrical run to turn the electricity off and then back on to do a easy disconnection/reconnection of the electricity to thermostat which did the trick. The thermostat came back to life and it worked. Now my tenant is enjoying hot water. This guys installation videos were excellent and where I learned about the valves! http://www.youtube.com/watch?v=LKhXoaRg6k4 Hope this helps. I will be getting mine inspected by the city as part of an existing permit for a remodel. Let you know if anything comes up after that, but it should not.

The Rinnai is made in Japan. Japan was making tankless hot water heaters in 1963. I had one while there and used it from 1963-1967. I have two now, my house is divided into two parts. I have never heard of one freezing. The Japanese use them on Hokkaido and it is as cold as anywhere in the U.S. When we have visitors (which is often) we can take three showers, was dishes and clothes at the same time and never fear running out of hot water. Saves a lot on gas too.

It should be a residential type tank 100 gal or larger, and needs a pressure regulator. My propane company came out and did the LP hookup after I installed the unit, I found they were happy to do this as I pointed out it was another unit to use their propane besides the stove...

Hi Gary, good question and i do not know the answer. I know the gas paloma i had could be plugged into a garden hose. Call a plumber who sells Rinnai and ask him, i found they are always willing to help or call Rinnai directly. Sorry i couldn't be of more help.
