I was told by a gas heating retailer that It's no longer legal to install a Rinnai Ultima II built-in model into an existing fireplace. Is this correct? Does the same apply to the console model?

Hi, Have the problems with the Ultima 2 inbuilt been sorted out, i notice that the negative reviews are quite old ?

Chris 3y

I can only answer based on the work they did on our fire about a year ago. The tech said that the temp sensor was not in the best position and that they have moved it. He moved our sensor to the new location and we have not had a problem since.

Peter 3y

Thankyou

Rinnai Ultima II console flued. Professionally installed in 2008. Noticed water stains on the ceiling where flue exits the roof. Found that a very small amount of water was dripping from a joint in the pipe before it exits the roof. Checked roof flashing around flue pipe, all OK. Only happens when heater is in operation. If I seal this joint will the water (obviously created from the gas combustion) run down the flue back into the heater or will it be evaporated when it gets closer to the heater temperature (the Ultima II flue does not get anywhere nearly as hot compared to the previously installed Vulcan Burwood heater!).

Peter G.4y · Ultima II Console

I have just installed a Rinnai Ultima 2 and I am wondering if there is only one heat setting? I have a normal sized lounge room and it takes literally hours to get warm. I set the temp at 25 and it has never gotten above 20. I can't seem to find any reference in the manual to heat settings except a reference to H and L but those do not appear on my heater's screen. would appreciate any guidance thank you

Rinnai DM 4y

Hi Peter,

We would recommend talking to our technical team on 1300 555 545 option 3, They can run through the operation of the heater with you.

Thanks Rinnai Australia

Mimmo P.4y · Ultima II

Well after reading all these reviews, I was about to buy this particular heater and it looks like I will be giving it a miss.

steve 4y

Honestly, given the chance , l would never go near this heater. Smart move.

Cold4y · Ultima II Inbuilt

I purchased a Rinnai Ultimate II heater vis some loyalty points program. It is a Flued Space Heater. The mistake was mine, not Rinnais.

We do not have a fireplace or similar, so it would be effectively an indoor heater. So I have been frightened to turn it on. It is near a window, so if it came with exhaust pipes or similar, I could kind of rig it up to pump the fumes mostly outside. It does suggest on the label on the side it is indoor/outdoor. I did read if there is too much poisonous fumes coming into the house, it turns off. I would appreciate some advice on what I can or can’t do in this situation. If there are suitable exhaust pipes then I’d prefer to buy them, than quietly fall asleep never to wake up. Please advise. It is still in its plastic wrapping, never been used, but it came via a loyalty program so the effort required to return it would probably be massive. Thank you.

Rinnai DM 4y

Hi Cold, Thanks for the question. The Ultima II heater is a flued space heater and must be installed by a qualified gas fitter. A flue will be required and the installer can recommend the best options for you depending on where you wish to install the heater.

This type of heater cannot just be switched on out of the box.

You can find out more information at the Energy Safe Victoria website here:

We also have a Rinnai technical help desk which can provide more advice and they are available on 1300 555 545 option 3.

Rinnai Ultima 11 Flued Space Heater Model REH-311FT(B) - Inbuilt The plumber/gas filter who installed the heater told me the heater draws oxygen from the room and that I should not close the door to the lounge while the heater is operating. I live in a 70 year old home that has wall vents in each room. Two vents in the lounge room. I can see daylight through the vents which means I have cold air coming into the lounge 24/7. I would like to block the vents off but I'm concerned about what the plumber said about the heater needing fresh air to operate. Can anyone help please?

Rinnai DM 5y

Hi Jestnan,

Adequate ventilation is required for the heater to operate, we would recommend calling our technical help desk on 1300 555 545 option 3 who can confirm the safest oprion for you.

Thanks Rinnai Australia

justnan 5y

Kerry5y · Ultima II Inbuilt

Our heater is only a few months old and its turning itself off and flashing 90. What does this mean and what do we need to do to fix it.

Rinnai DM 5y

Hi Kerry,

We would recommend contacting our Technical team on 1300 555 545, option 3. They can assist you with technical advice or advise if a service call is required.

Carolyn F.6y · Ultima II Inbuilt

My ultimate ll has no power to start it does it have a battery if so how do I change it

steve 6y

No batteries that l know off, and lve had to have quite a lot replaced on mine. Only electricity is by plugin wall cord.

Rinnai DM 6y

Hi Carolyn F, thanks for the question. There is no battery for the Ultima II heater, power is supplied through the power cord on the unit. We would recommend testing the power point with another appliance if you can, otherwise a service call may be required.

You can book via the Rinnai Australia website here:

Rick6y · Ultima II

Like Kylie O. a month ago, where can I get a copy of a REH-301FTB manual? I have been searching online without success. Thanks

Rinnai DM 6y

Hi Rick, thanks for the question, we have sent you a private message so we can send a copy of the manual.

thanks Rinnai Australia

Fran526y · Ultima II

I was thinking of purchasing a Ultima 11 I like the look of it, but it seems most of the reviews are negative, I guess I should look for something else?

steve 6y

From personal experience yes, about every 2 years it is costing me money, combustion fan again has just been fixed, at a cost of $600, and heater is only 6 years old. First fan was a little after only being 2 years old, just after warranty expired.

Fran52 6y

Thank you Steve,I think I will do some more researching, a different brand probably

Rinnai DM 6y

Hi Fran52, Thanks for the question, the Ulitma II has been a successful product for many years where we have sold 10,000’s of these heaters. Like most products there maybe issues from time to time. These products are fully backed with warranty so if there is ever an issue the product is covered. For best peace of mind it’s important that these types of products are installed by a licensed tradesman.

Thanks, Rinnai Australia.

steve 6y

Except warranty was only 2 years, and thats when l started having issues. Two years for such a great heater that cost a considerable amount to purchase. And thank you rinnai for your emails contacting me that basically said because work wasnt done by service agent ( we all dont live in major cities and cant wait a month to get heater fixed in middle of winter), although it was done by guy who was your service agent here for over 20 years, and warranty had just expired, badluck, no further replies. Is it really acceptable to be paying 600-700 for combustion fans on this model every few years?

Kylie O.6y · Ultima II

Why can I not find a manual for a REH-301FTB?

Rinnai DM 6y

Hi Kylie O,

The REH-301FTB is the Ultima heater and has been discontinued for a number of years.

We can arrange for a copy to be emailed to you and we will send a private message so you can send us your email address.

Thanks Rinnai Australia

Rick 6y

Hi Kylie O, Did you receive a copy of the manual for the REH-301FTB as a PDF? If so are you able to forward it on if I provide my email address? thanks

Gypsy6y · Ultima II

I would like to know how to turn the timer off. My sister keeps pushing buttons whenever I leave the room. Can anyone help please?

Simon 6y

The instruction book is online external link

Gypsy 6y

Rinnai DM 6y

Hi Gypsy.

Gypsy 6y

I must have been having a blonde moment, couldn’t work it out. So, I just turned the power off for about 10 secs. Voila, all fixed. Thanks for the help.

btguy6y · Ultima II Console

I desperately need the combined gas inlet union/copper elbow that connects the heater to the gas line. I'm trying to find one, because my local gas fitter tells me rennai parts for the REH-300 FTC are impossible to find. The model also seems to go by the name of 'high efficiency 30'. Any alternative inlet elbows that would fit, or even the spec. so I could get one fabricated would be great. Thanks!

Rinnai DM 6y

Hi btguy,

Thanks for the question, we would recommend contacting our Technical Department to discuss this matter further. They can be reached on 1300 555 545 (option 3).

btguy 6y

Thanks, I'm going to call Tuesday. I'll post the reply for anyone else with similar issue.
