Installation: Electrical Requirements

13Mb product manual is a big download ... electrical info page 13:
Recommended both water heaters require dedicated single-phase 15 amp 120Volt line with correct polarity. This is 14 gauge wire and 15 amp breaker for each unit.
I would put both water heaters on surge protection and GFCI. Most water heaters are not protected from surge, and manual says line noise can affect operation of water heater.
Your local code would say if GFCI is required. Install GFCI breaker in main panel if required.
Install inline surge protector: Or add main breaker box protection.

Can i use a tankless hw heater to supply my hobart am15 dishmachine

Don't install tankless, because repairs, installation, operation, maintenance, replacement etc are expensive.
And the thing can be unreliable since you are connecting a computer chip and sensors to gas line, water line, electric line, and to a gas burner with vent to outdoors ... and each of these systems has problems on its own without a computer chip that can fail at the first electrical surge.

Otherwise call Rinni for specs.

Ask about the 4 year warranty for residential installation.
Ask about deliming each year.
Ask about exposure to hard water, and water impurities, and water problems. Tankless cannot be exposed to more than 11 grains hardness.
Ask about recommended yearly maintenance requirement.
Ask why there are no service manuals, and how technicians know how to fix the thing without detailed service manuals.
Call around locally and see who services the thing, and ask if there are service problems.

Whirlpool 6th sense natural gas water heater 50 gal. Bought brand new today. Upon installation, discover low gas pressure running to unit. Turned out that gas line had under ground leak so had to turn...

1) Be careful before you Call Whirlpool 1-877-817-6750.
Be careful what you report so not to void warranty because installation protocol was not followed. Whirlpool will cover gas control valve, and possibly the installation of valve which takes about 15 minutes and does not require emptying water heater.
************So make sure you report installation that is consistent with installation shown in manual.

2) Whirlpool will also answer this same question later today with invitation to contact them.

3) Copy following link to identify gas control valve, and download service manual:

4) If dirt or debris gets into gas control valve, it will cause it not to work. Such as broken gas line. Debris can enter gas line.
Or if too much pipe dope was used on gas connection, or stray teflon tape got into line and then into valve, or end of pipe got dirty during installation, and then dirt got into gas control.
Take off gas line and use vacuum cleaner to see if something can be removed by suction. Clean up the joints.

5) It appears you have ordinary Honeywell gas control valve on atmospheric vented water heater with 9 year parts-labor warranty..
Unknown error code, so it is hard to look up solution in service manual.
Add a comment if you want expert to look up error code in service manual.

I have a Rinnai Tankless and I have a problem with the water going from hot to cold so I called to have it serviced, I was told that it needed to be flushed to remove settlement from the unit. Okay we did...

Did service man clean combustion parts and check for loose wires, proper venting etc?
In other words, is the tankless up-to-date on yearly required maintenance?
Did you check outlet for power?
Is the unit properly grounded?
Is the unit vented properly, and set for correct altitude?
Is the thermostat set too high?
What does the manual say about maintenance?
It certainly says to clean water filter frequently, and clean combustion parts yearly, and bleed air from gas line, and delime yearly.
Is your water heater exposed to more than 11 grains hardness in water that will cause failure due to clogged parts?

Does service man have a service manual for your specific water heater?
Does anyone have a service manual for your water heater? Probably not, which means service man will be guessing at one thing and then guessing at the next thing.

Problem could be PC board failure.
Similar to failed motherboard on computer.

Let's be frank:
Do you want the cheapest solution?
Or do you want to chase around trying to find why a complex computer chip connected to electric outlet, electric sensors, gas valve, water valve, water line, gas line, and gas burner with vent to outside has decided to stop working?

Cheap solution, Buy tank-type gas water heater for $350 at local box store. Just get a simple one off the shelf. Don't worry about warranty, because it means nothing.
Select Whirlpool, AO Smith, American, State, Reliance, Craftmaster, Kenmore because these are made by same company and can be repaired and maintained by homeowner, and service manuals are available, and any plumber knows how to fix em..
Avoid Rheem, Ruud, Richmond, GE, for all same reasons except in reverse.
Read the manual, perform the required maintenance.
Keep the air intake clean.
Install water heater yourself same day, turn up the temperature wait, 1/2 hour for tank-full of hot water, and take hot shower.

Rheem-Tankless-water-heater I am showing a C2 then 11 flashing on my thermostate. what is wrong.

Before calling service technician, open following links for common error codes, Rheem chat, and possible manual.

Error codes are start point for troubleshoot.
C2 11 is 'no ignition' or 'gas shut off vale is not open'
Gas shut off valve handle must sit parallel with gas line.
This kind of error code can be air in gas line, improper grounding at electrical outlet, bad igniter, shorted solenoid, loose connections, etc.
Most tankless manuals recommend yearly service, and that type of work usually covers cause for most common error codes: for example checking gas pressure, gas line, air in gas line, clean and check burner and combustion parts and igniter, inspect that vent condensate is properly draining and vent has good draft, clean water filter, clean air intake, check for loose wires, delime heat exchanger, test outlet with circuit analyzer etc.

No hot water code 11 keeps coming on had system for 5 years

Before calling service technician, open following link for error codes, Rheem chat, and possible manual:

Error codes are considered start-point for troubleshooting.
Error 11 is 'no ignition'
Without ignition, the burner will not turn on and heat water.

This problem can be caused by low gas pressure, air in gas line, defective tankless parts such as gas solenoid, loose electrical connections, improper electrical grounding, bad igniter, etc.
Problem can also be caused by combination of problems.
Good news is that error code shows 1 code and not multiple error codes that can indicate larger failure including PC board.

Each tankless instruction manual recommends yearly maintenance where technician will clean burner parts, bleed gas line, check gas pressure, check air and venting, etc.
Yearly service covers the cause for most common error codes.

No hot water. Constant beeping at the tank. Tempature gauge flashing 11.

Before calling service technician, open following links for Rheem troubleshoot resources including Rheem chat and typical service manual and typical product manual.

Error codes are start place for troubleshooting:
Error 11 is 'gas is inadequate' or 'ignition failure'
Open gas valve so handle is parallel with gas line.
Bleed air from gas lines.
Check that appliance is grounded.
Check igniter wires and harness for damage.
Check that vertical vent length does not exceed limit.
Other causes: Gas inlet solenoid valve, bad igniter, solenoid valve, flame rod.
