Question about Rinnai RHFE-556WTA Direct Vent Heater NG Air Conditioner

1 Answer

Max temperature for Rinnai 556WT restricted to 74 degrees

The landlord recently installed these heaters throughout my apartment complex. Problem: the Max. settable temperature for my Rinnai 556WT heater seems to be restricted to 74 degrees. The user manual shows that it has an 80F to 60F temperature setting range. They probably set that restriction because they're footing the gas bill. How do I disable that temperature restriction? I looked in the manual and it doesn't mention anything about the possibility of restricting the maximum settable temperature. Please advise.

There is no way to restrict the setting and keep it UL approved. If you cannot get the heater above a certain setting you have either too small of a heater, too much outside air entering the apartment or the gas pressures are not great enough.

How do I turn it on? I press the "on" button and


The manual says:
http://www.coinwash.com/temp/rinnai.pdf

"For the name of the Authorized Distributor or Installer nearest you, please contact your local HVAC dealer or gas service technician, visit the Rinnai website (www.rinnai.us), call Rinnai at1-800-621-9419 or write to Rinnai, 103 International Drive, Peachtree City, Georgia 30269"

Manual says that the remote is for setting temperature.
When you turn on hot water spigot, tankless water heater will heat the water to the set point temperature.
If water heater is not set up to use remote, then tankless unit will heat to 140 degrees F.
"With the MCC-45-4US remote control installed the water temperature is adjustable from 96
to 180°F. The water temperature cannot be set to a temperature other than 140°F
without the use of the MCC-45-4US remote control unit. If you require a temperature
other than 140°F you must install the MCC-45-4US remote control unit."

"Error messages are displayed on the remote control units, simplifying service calls."

Page 9 of manual shows hot to set temperature using remote.
Water taps must be shut off to set temperature.
Circulating pump must be turned off.
"Simply press the H or C button until desired temperature is displayed"
"green in-use indicator will display"

If your unit is not working, the manual says to contact local plumber.

RINNAI Heater 1001FT Gas heater; was wondering if water required?


It shouldn't give an odor at all unless it hasn't been run a lot or cleaned. Rinnai recommends blowing compressed air through the front grates once a year. The pan is to catch condensate from the venting system. Hot flue gases contain moisture, which is a byproduct of burning propane. When this hits anything below 212 degrees, it will condensate and collect in the pan. The heat from the unit evaporates the water, thus making it a good system of condensate disposal. However, additional water can be added daily if you have problems with dryness in the air. The only other thing that can cause a bad odor is a compromised heat exchanger. You should have it checked, and if you don't already, have a CO detector in the room

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 556wta gas heater keeps shutting off


Return the heater while you can, we bought 2 of these and have had the same problem with both of them. One of the units they replaced all the guts and still had to replace it. The other unit is out of warranty and I am considering just replacing it to save on repair costs which will eventually equal more than the cost of the unit. The thermostat wire is located in the back and can be stapled to the inside wall up off the floor. It was not installed properly. Good Luck!

OK, sounds like a sensor problem to me. The temperature reading is done on the backside of this unit. Remove the top cover and with a flashlight in hand, look for a small black rubber probe with yellow wires attached. You will find it about 2 inches above the floor and on the right hand side (when viewing from the front). Make sure this probe is not being influenced by the venting system and showing a “false” reading. If the vent pipe (the one covered by cloth) is close to it, the probe is made that you can relocate it out of the way of the vent. You will need to get to both the backside of the heater and go inside the heater cabinet to do this properly. If the vent is a few inches away and not influencing the probe, place a cold cloth on the probe and see if the temperature drops. Then a warm clothe on it to see if it rises. You could have a bad probe. List your model number and I can get you a part number.
