SOURCE: need to wire a zone control for a closed system with a circulator

Tankless water heaters for domestic use fire whenever there is water flow. As long as the pump flow rate exceeds the minimum flow rate of the appliance, the heaters hould fire (the return temperature needs to be less than the set temperature as well). Boiler systems will typically require a thermostatic signal (call for heat) and water flow before they will fire. Tankless heaters are designed for residential use and only require pump flow to fire.

What is the outside temperature? If it it is below freezing, you might have a frozen pipe. Using a plumber torch heat up the pipe, if it works, replace the insulation using a heavier layer.

SOURCE: Ignition problem: I have a gas

This is an error code 12, not 12 degrees. You have a short on your low voltage side by the sounds of it.. First disconnect the controllers inside the heater. Turn of the power first, 2 screws top and bottom to take the frnot panel off. Follow the low voltage wires (not the power point ones) to the PCB on the ride side and disconnect them both. Panel back on, power on and try the heater again. If this fixes it you have a short circuit in the controller or the wires leading to it. If not the most likely short circuit is on the thermal fuse which loops around the heat exchanger. This will need an expert, Perth has plenty north and south of the river. Give Rinnai a ring first, they have some good staff in Perth who might help.

Im looking for the best option to get a Rinnai unit that would supply water at 30c or just below. i was going to buy the REU 55RT but looking at the manual i dont know how low the temp can get


Most tankless are preset to 120 degrees F.
30 degrees C is 86 degrees F.

If you want adjustable product, then tankless is not best choice.
Tankless are high tech gadgets with multiple interrelated parts controlled by sensors feeding information to control board. Everything internal and external has to be working correctly for tankless to work at all.
Most tankless brands do not suggest self-install, or self-adjustment, or any adjustment for reason given above.
You would be better off buying typical tank-type gas or electric and then thermostat adjustment is simple.

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.
Fixya has specialists who will talk to you by phone about your problem for a fee.

I need a service manual for a Rinnai Infinity 26 continuous flow hotwater system - REU-VR2626WG-AK Can you help me? Linda


I left Rinnai only about a year ago at a levle of State Service Manager. I had been asking for service manual for for many, many months. Basically as far as I am aware there is not a service manual for the WG. If you google Rinnai Infinity 26 manual you can get a PDF from the Rinnai NZ sales site but his dates baack to 2003. Unfortunately there are major changes to some of the components but it might be better than nothing. Just don't use part numbers, and you might find bits to check that now have voltage and resistance differences. Send a message to Rinnai complaining, I encouraged people to do so even when I worked for them!

No power to keypad


I had a similar problem, the water flow control device was bad.
If you disconnect Connector B2 and the unit will start, then that will confirm the problem. Rinnai has a new improved part for replacement.
