I just moved into an apartment with a Rinnai energy saver gas heater. It is incremented by 4 degrees...60,64,68,72 etc. 64 is a little too cold and 68 is a little too warm. Do you know of a way I can set it to 66 or 67 degrees? Any help would be appreciated!

SOURCE: error code 11 on my rinnai

A code 11 also means that it might not be getting any gas. On thr right side of the unit you will find a small door. open it up and make sure the valve is in the open position. If it is, you should contact your gas company to come and diagnose what is going on. The Rinnai is not a do it yourself fix it type of heater.

SOURCE: Rinnai heater turns itself off


You could have something as simple as an air hose off, or a piece of carbon on the flame sensor. Your problem could also be a gas valve , which is much more complicated. If you are handy with tools you could be able fix either quickly. If you’re not good with tools you will need to get some help. Either way you have to have some back ground info on your heater. Get in touch with Rinnai and get a service manual for your unit. They cost around $15. If you have to call a service guy, use the Rinnai web site to find an authorized service person. Don’t just let your fingers do the walking and get some guy who has no idea what a Rinnai is. You’re only asking for trouble there. Your unit is a little older so don’t be surprised if parts are hard to find.

Good luck,

SOURCE: Rinnai Energy Saver 302 convection gas heater has

Energysavers have fixed flue lengths, more likely your problem is the thermistor at the bottom left of the heater inside the grille getting a false temp reading. Look for yellow wire with a black bulb (like a drop of water). measure the air temp next to it while heater running, if its above room temp down there the heater will turn off early. It needs to be clean and have unobstructed air flow over it for it to work correctly.

Rinnai 556F Not Exactly and "Energy Saver"...

Raise the thermistor. It is a black rubber probe located on the back of the heater close to the coldest spot in your home, the floor. Raise it a few inches. To do this you will need to unhook it from its holder and open the front of the heater to unravel the extra length of yellow wire.

Rinnai 1004 heats to a temp 4 degrees higher than set temp, adjustment?

You can adjust the position of the room air sensor found on the back of the unit between the heater and the wall. It is a black rubber bulb with yellow wires. There is a few inches of extra wire you can extend higher to get a more accurate reading of room air. While you are back there, check for drafts that will give you false readings.

Rinnai 551FT (I couldnt see it on list!)

Try vacuum cleaning the filter as the heater shuts down to protect itself from over-temperature. NB-turn off the heater before doing it. And yes, you add water to the tray (...carefully) - this increases the apparent heat. Peter
