Rheem EcoSense by 7.4 GPM Tankless Water Heater Natural Gas High Altitude - Answered Questions & Fixed issues

Question moved from Kitchen Ranges. You need a High Altitude Conversion Kit from the maker. Then you need a gas registered technician to fit them and adjust. Standard altitude is up to 2,000 feet above sea level, https://www.google.com/search?q=gas+water+heater+setting+for+altitude+above+sea+level ..

it will be close to the fire ring and is a photo electric cell it registers flame light and cuts off the fuel supply with in seconds if the flame doesn't appear

I have the exact same problem with error code 13 on my Rheem/Ecosense 180dvn . The unit ran good for at least a year, and then I started getting the same error 13 every few minutes. I called the Rheem service department, and they told me to check the vent installation as well as the gas pressure. I reinstalled the vent with new seals. I only have about 6 ft of vent, so there should be very little resistance. I checked the gas pressure, and it shows 9 in H20 pressure, which is well in the range recommended. The service center scoffed at the suggestion that it could be their circuit board. I am totally at a losss and at the verge of ripping this very expensive installation out of my attic.

Air or possibly their loose our bad faucet or cartridge somewhere

Gas meters are usually rated in cubic feet per minute (CFM) not BTU. there are 1027 BTU per cubic foot so do the math. Try the link below Btu rating on natural gas meter

Is it a new install? If it worked befor it is probably in need of ingiter cleaning. Make sure you have not blown a breaker first.

Error code 13 referrs to the gas pressure and or venting issue. Please ensure the gas pressures are correct and the vent is free of any obstructions. It also may be a failed ecu chip. Service tech may be required but first check for obstructions in intake/exhaust venting. Bird nest- bees and foreign material.

if you are saying you instaled it 8 months ago, if you are not licensed you have voided your warranty,,, if you had it installed you do have at a min of 1 year labor and can call your installer, when they started doing the tankless water heater there installers are supposed to go to classes for installing these units and the company's that manafacture them will provide you with assistance on any problem, in your book it will tell you what is wrong on the code page if you don't have the manule go to there website they have all the codes listed,,

actually, does it give you a big rumble? if it does, then your problem is that the meter's btu's are not high enough and there's too litle gas getting to the heater so it's blowing itself out, basically. you'll need to call your gas provider and ask for them to bring in a higher btu meter. around 220,000 btu meter is best, so your furnace and gas stove(if you have one) dont take to much gas themselves, meaning dont get a 180,000 btu meter, because it would only be able to supply the heater.

how many times does the light blink? this is a code

1) Copy following link for steps showing how to run white vinegar through Rheem tanklessx heat exchanger to partially remove scale that coats heat exchanger and reduces unit efficiency and causes error code IL:http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#de-lime2) Tankless are prone to scale inside heat exchanger and require yearly deliming to mitigate effects. Do the required yearly maintenance to avoid common error codes.3) Expected cost of maintenance and repair is more expensive than estimated $1-8 monthly energy-bill savings from owning tankless.

Rheem, Richmond, Ruud, and Paloma are all the same manufacturer. After about 9 months, my tankless RTG-74PVN started giving me error code 11 and cold water!. I fixed it by cleaning the burner, as shown in this video:www.howtolou.com/clean-a-burner

Multiple error codes can mean PC board failure.
C2 11 is no ignition.
Error 24 is malfunction of operational switch: "press max or mim button on PC board, or replace PC board." On some models, max and mim button can be located just above dip switches, and rotates with screwdriver. See diagram in manual.
