Bedsides buying the RL 75iN Natural gas Rinnai unit, what else do I need to buy? I am replacing a 55 gal tank hot water heater, heated by LP, and switching to natural gas. My entire house is being switched over from LP to Natural gas. Thanks in...

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

If I remember right, mine is a 6gal unit. It works great for me. I went to Park Rose Hardware, (164th & 1st st here in vancouver) with a breaker I pulled from my trailer & bought another 1 of the same kind/brand. It sucks a lot of power so I wanted it to be on a breaker by itself. You can come look at mine if you live in my area.jonesy

This is natural gas. Abbreviation in descriptions will be "NG" for natural gas, or "LP" for liquid propane. They make conversion kits to switch between the two but I would highly recommend getting the correct type of unit from the start. The kits are expensive and often not all that easy to install.

I installed this unit last February. I have a 375 gal tank and home only uses gas for the Rinnai and my home furnace. Over the summer/fall when my furnace is not in use, the gauge barely moves on my tank. My best guess is that a 20 lb tank would last 2 months. Consider what fittings and connections you might need because the typical 20 fitting for a grill might not give you enough flow for the Rinnai.

oops, you did ask about natural gas. Sorry, we used propane, no natural gas company up here. But it is a 1/2 pipe.

Yes it is. I switched over from an LP only unit and I'm so glad I did. Recovery rate is faster on gas but it feels hotter on electric so your able to use more cold water and extend usage.

The LP5500 unit is designed for use with a 20 lb. or 30 lb. tank, but can be utilized with a larger tank. To ensure the unit will properly attach to your larger LP tank, we recommend contacting a local plumber, or the propane company that supplied the tank. Generac does not offer a kit or parts to attach to any other tank, but your local plumber should be able to ensure your connections are proper and meet your local code. The regulator inlet pressure from an LP tank should be between 30 and 100 psi. Please note that any damage to the unit due to utilizing a larger tank will not be covered under warranty.

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.

My two Rinnai tankless hot water heaters require electricity to ignite the LPG which fuels the heating of the water. Therefore, I have had a generator installed to provide the necessary electricity if and when I incur an electrical power outage. So far I have not experienced a power outage. I am told that the Rinnais will need to be "reset" whenever a power outage occurs. Once reset, the opening of a hot water faucet will signal the Rinnai to use electricity to ignite the LPG and heat the water. I do not know if rhe Rinnai can be connected to a battery which will provide the needed electricity. Contact Rinnai or an experienced installer in re the battery question.

I don't believe so. It would probably be easier seeing if some retailer will simply swap it out for you. The natural gas units are usually about $20 more expensive than the propane units.

No. I had to hire a plumber to run a separate line From my natural gas source. He also made me a selperate line from the generator to the gas hook up. This generator needs a specific amount of PSI to do the job right. Hire a licensed plumber to do the job right ,for the safety of your family. having said that,I am extremely pleased with the generator. I finally have peace of mind !

This is propane (L.P.) Only. Can not be converted to Natural Gas. Have to get one set for Natural Gas and then convert the orffices for natural gas. Look for a conversion kit get made for your unit. It may not be able to convert it.

The hard water would affect it. Rinnai recommends flushing it periodically to remove scale and lime. I guess you would just have to flush more often. Also, your unit will not function without electricity. So no power, no hot water.

Plumbers are in business to make money . It takes a lot of work to install a gas water heater .It took me a half an hour to install my Rheem .My electric dropped dramatically .Gas prices are rising and not environmentally friendly !!

you need to find out what the heater is set up for natural gas or propane. If it is propane then of course you can get a tank delivered. if it is set up for natural gas then if you live where it is in the road or if you have a natural gas water heater or funace then you could have a plumber pipe a line to where you want it. just make sure to find out what the heater is set up for. You can buy the new items to convert it to what ever you are going to be using.
