Laing UCT-909-TANKLESS UltraCirc Tankless Water Recirculating Pump

This is designed to maintain the proper flow to fire the heater. Please be sure the pressure in the house is at least 5 psi over the minimum required for your unit.

contact your gas company if the error code is "12," indicating that the gas supply was interrupted.

have a good day !! In LP models, the 12 error code may also appear if the LP gas supply has gotten low. To clear the code, replace or refill the LP gas supply.

Not for sure what your root cause was and I know it's a little late but I just suffered this same exact scenario on the same water heater. Storms came through, power went out, power came back on and the water heater keeps blowing the 3 amp fuses now. I removed all the cables and plugged them back in one at a time. When I plugged in the Fan Motor connector the fuses blew. Installed new fuses with the connector out, the Fan Motor was putting out 150 VDC through the connector port (on main control). I pulled the control from the unit and Q1 is visible blown and disintegrated on the control board. Obvious control design issue. I've ordered a new control and will put a surge protector on the heater now when the new control comes in. Very disappointed that this was not caught in controls testing within the manufacturers facility. New control is not very cheap. Half the cost of a new Heater. Hopefully the Fan Motor survived the high voltage with the fuses blowing. I'm putting this here for anyone else that suffers the same issue on this water heater or the Richmond equivalents as they use the same control.

Two things- Clean the sensor rods or replace(cheap and easy with YouTube instruction video) and at the same time replace the main program chip (also a easy plug in chip). The whole repair takes two hours for a homeowner and costs about 50 bucks for a chip. These are easy and generally the flame sensor rod is the culprit. The code may also be the limit switch but try EZ and cheap first. See You Tube..

There is an adjustment knob to control how hot the water can become. There might be a problem at the tap (however, if this is the case, you would still get hot water everywhere in the house). If the entire house isn't getting hot water, and the knob is set at the hottest water, you probably need to get the hot water tank replaced.

Rheem water heaters should not be converted from propane to natural gas. The burners have been optimized for the rated gas and will not work as well after conversion. (Unlike ranges where the gas/air flow ratios can be adjusted when the burner orifices and regulator are swapped, the water heater doesn't have that option.)

I wish I had better news for you. I recommend you get a new water heater for the LNG service; it will be safer and more efficient.

there is no pilot- it is lit with a ignitor. If you have problems the unit needs a service cleaning of the flame sensor rods.
