Sounds like you're not getting enough combustion air.
If you have a draft motor or blower make sure it is running.

Flame burning too orange


You need to get a Plumber or Appliance Tech to come out immediately and check the fuel to air ratio. You are not burning your fuel at the proper mixture. A blue flame is good, yellow-orange is bad.

Normally this is because the burner area is dirty or the pressure regulator may be set too high/low. The black marks are a sure sign that your ratio is too rich and it's just going to build up more soot and become unhealthy and dangerous.

Whirlpool/Honeywell hot water heater light flashes 5 then 7 times and won't light. Burner is clean and all contacts are good. Out of warranted.


Copy following link to troubleshoot by type of gas control valve, including directions for cleaning air intake screen, and or replacing gas control valve:

http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html
http://www.thetankatwaterheaterrescue.com/forums/forum3/

7 flashes: Gas control valve might be bad.
4 flashes: FV overheat, clean air intake.
Soot indicates clogged air intake slowed combustion venting possibly causing overheating and lockout. Clean air intake screen located on bottom of unit.

My 50 gal lp water heater made a slight boom sound and now when i lite it and turn on the main bunner it snuffs its self out


1) Call manufacturer with model number and serial number appearing on label on side of water heater.
http://waterheatertimer.org/Water-heater-manufacturers.html

2) Copy following link to troubleshoot by type of gas control valve:
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent
http://waterheatertimer.org/How-to-replace-thermocouple.html

3) Product manuals today recommend yearly service, and yearly cleaning of combustion parts, and to keep air intake clean.
If air intake becomes clogged, or combustion parts get dirty, it can slow the exit of combustion gasses, and this will soot the burner, and clog burner ports, which means slow lazy yellow flame and incomplete burning of released gas. So unburned gas is present in combustion chamber and up the flueway. The ignition of unburned gas can cause explosion of various intensity ... and the 'boom' sound you heard.

The explosion certainly overheated combustion chamber and tripped FVIR system.

4) Since each manufacturer has different FV system (flammable vapor ignition retardation system), and each manufacturer has continued to make changes over time in FV systems, the solution for tripped FV will vary by brand and age and model of water heater.
For example the intellivent gas control can be reset in some models, while other models require replacement of parts ranging from gas control valve to FV sensor to glass vial, and include possibly full replacement of water heater.

Gas boiler makes a lot of black sut


This is dangerous condition. Call service technician immediately, and they might put the unit out of commission until repairs are made.

Locate manufacturer's website, and call manufacturer to get name of local technician qualified to work on unit, and this will get the unit back into working service quicker.

Soot means burner is not burning all the fuel, and venting is slowed.
Possibility unburned gas is entering flueway, and could cause explosion.
Clean burner parts, check vent draft, check gas pressure.
Catch unit up on required yearly maintenance.

How to repair code 13 for tankless water heater


10-15-2012

Code 13 is probably Rheem, Richmond, Ruud, Paloma etc tankless.
Copy following link for troubleshoot resources:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Error 13 is oxygen depletion sensor
Imperfect combustion.
For example if tankless does not have required maintenance, then burner can get dirty and clogged.
This will cause unburned natural gas to rise inside hot flue pipe causing risk of explosion and fire, or in case of propane gas that is heavier than air, the gas will build up inside combustion chamber and cause explosion and fire.

Rheem water heater 42vp40sf and the fvd interface failure code is flashing. how do i fix this?


Call Rheem

TRD is flammable vapor system. Typically there is a glass bulb or fuse located in the combustion chamber.
See example image:
http://waterheatertimer.org/images/FV-TRD-glass-fuse-300.jpg

Remove the burner and look for the evidence of broken glass bulb that holds the air intake open.
Air intake is located bottom of combustion chamber, and bulb breaks causing metal plate to snap upwards and close off air supply to combustion chamber.
Rheem will have exact part number and possible instructions. Other people have wedged the air intake open to get system working again, but I do not know if that will work with your model water heater with electronic control. Working around the FV system exposes home and people to flammable vapor ignition and explosion when water heater is exposed to flammable vapors.
Example manual with illustrations.
http://waterheatertimer.org/pdf/Test-if-thermal-release-device-needs-replacement.pdf

Clean burner and pilot orifice and combustion chamber while burner parts are removed. Also clean air intake.
When burner is removed for cleaning, the access door gasket might need to be replaced.
Your product manual and/or Rheem will have that part number.

I HAVE A 10 GALLON ATWOOD WATER HEATER IN A PARK HOME THE PILOT LIHTS FINE AND STARTS THE GAS OK WATER IS NOT GETTING HOT IT LOOKS LIKE SOME OF THE FLAME IS COMING OUT OF THE HEAT TUBE GETTING CARBON ON...


I would definitely have the burner tube cleaned and adjusted if necessary. Sounds like a possible spider web in the tube, as well as have heat chamber blown out with compressed air if at all possible to remove soot build up. Stand back when blowing it out, or you"ll be covered in soot.
You can buy a long brush for cleaning barbecue burners, that work well.

ON MY ATWOOD WATERHEATER IT LIGHTS BUT PRODUCES A LOT OF SOOT AND DOES NOT SEEM TO FIRE UP LIKE IT SHOULD


You need to start by cleaning burner tube and pilot intake , sounds like spiders have probably spun a web in there. If flame is yellowish, it's not getting enough air. You can buy a barbecue burner brush, long and flexible, and run it through burner tube to clean out web, and if pilot is yellow as well, there is a small hole in side of fitting where it attaches up near burner that needs to be cleaned out with paper clip or even better, compressed air. After cleaning burner, adjust air shutter to get nice blue flame, with just a hint of yellow at tip. The idea there is to get blue flame, but not a roaring flame that is jumping off the burner. A spider web in there will usually allow propane through, but restricts air mixture, thus causing yellow flame (rich mixture) and soot to build up.

Pilot won't stay lit


What color is the pilot flame? Yellow/orange or blue? Look at the tip of the thermocouple where the pilot flame is heating. It should be a smooth round tip. If the tip is partially burn't off or ridgid, replace the thermocouple. After the pilot is initially lit, does the burner come on too? Take a flashlight and look up inside the water heater above the burner. Do you see a lot of soot build-up? Light a match at the top of the water heater at the draft diverter (it attaches the venting to the water heater) and blow it out and see if the smoke gets sucked into the diverter or blown out. It should get sucked in. If not you may have vent blockage or soot build-up.

My pilot flame is too high . What could be causing this ?


If it's an Atwood and just recently started burning a yellow, higher flame, look closely at side of fitting where the pilot tube is attached to mounting bracket. You should see a very small hole in the side of that fitting. Take a paper clip, or something as small in diameter, and poke around inside that hole to clean it out, or shut pilot off, and use compressed air, to blow into it, to clean it out. Now re-lite your pilot and see if you have a nice blue flame now. That little hole is your air mixture for the pilot and sometimes debris clogs it, thus causes (rich mixture) yellow/red flame, which will also cause soot build-up in the chamber, or even on outside cover. Let me know if that cures it.
