You must get more air to water heater, and check venting .... immediate CO poison danger.
Call qualified plumber immediately.... because deadly carbon monoxide is not being vented properly.

SOURCE: Junkers gas water heater automatic ignition not working

Yes that is going to be the contoll valve on that heater. You can probley fix it very easy with the right part. You will need to locate a plumbing supply over there in the UK. Give them the make and model number and tell them you need a unitroll gas valve for it.

Is the vent fan working well and can you feel unobstructed air out the termination fitting outside?

SOURCE: Whirlpool Water Heater flame goes out shortly after being lit.

This problem sounds as if gas pressure to the burner is to low, check mnfr's plate on heater for the correct burner manifold pressure, you will need a manometer or a guage that measures inches of water column, set the pressure correctly and the burner should stay lit.

SOURCE: Atwood water heater - pilot light and flame malfunction

Michael,
The thermocouple sensor may not be in the best position to sense that the pilot is lit.
Adjust the thermocouple mount or simply bend the thermocouple "wire" so that the pilot flame is touching the tip.

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.

Black smoke coming out of exhaust


1) Danger. Sooted smoke indicates incomplete burning of gas, clogged air intake, dirty combustion parts, bad vent, and lazy yellow flame, and absolute danger of fire or explosion of unburned gas in flueway. Call for service immediately.

2) Add comment and include more information about brand, type and model of unit. And include if this is gas fireplace, gas water heater, stove etc. For more possible help.

I have a new Atwood G6A-7 water heater. The pilot lights fine but gas flow, when it turns on, is so strong it will blow the pilot out. Certain times, it sounds and looks like a mini fire ball going


Clean burner tube with proper brush, such as long spring type for bar-b-Q burner tube that are available at most hardware stores, and make sure you have new burner tube aligned properly (straight on) with brass orifice on gas control. Then be sure to adjust air shutter for nice blue flame, with little orange at tip. Do not give so much air that flame roars or jumps off the end of the burner tube. Too many people think more air, less fuel, but actually, when flame roaring and jumping off end of tube, the heat passes through faster and it takes longer to heat the water inside the tank. Like I said, only enough air to have quiet, steady blue flame. If your not giving it enough air, you'll see dark soot on trailer above water heater, which indicates burning too rich, need more air, or perhaps pilot is partially plugged. Pilot flame should also be blue, not yellow/orange. Small air intake hole on side of fitting just before pilot tube can get spider web, or debris in it as well. Use air to blow that out or a piece of wire like a paper-clip to clean inside that hole.

Reliance
2nd and 3rd digit of serial number is year

What color is flame? Should be clear blue.
Pilot is burning so thermocouple is good, and sitting in pilot flame.
Pilot flame should be clear blue.
Otherwise clean burner parts.

Is water at tank hot??
If burner is not turning on, the gas control thermostat is probably bad.

Kenmore Water heater, Model # 153.339462, Pilot lights, burner burns for approx. 10 - 15 minutes then both go out. after which it is more difficult to light the pilot. I need ideas please


Clean combustion parts, clean air intake, get more air to water heater and see if problem continues.
Look at color of burner flame and pilot flame: if flame has yellow-and-orange instead of clear blue flame, then combustion parts need cleaning.

Pilot and burner problems can be caused by bad thermocouple, thermocouple not sitting in flame, weak pilot flame due to dirty tube or low gas pressure, air in gas line, no draft up vent, backdraft coming down vent, dirty combustion parts, clogged air intake, insufficient air, insufficient air quality, hot attic, bad gas control valve, etc.

I have an orange flame on the burner instead of blue


The difference between an orange flame and blue flame is the amount of air in the combustion process. SO if the flame is orange it is being starved of oxygen. The gas burns dirty and soot is generated.

Sometimes with an older heater the exhaust venturie becomes plugged and carbon monoxide is released into your home- in this case your heater would make a woof or poping sound when starting up or shutting off. This is a dangerous unsafe situation and professional help is needed.

What you can do is try to make adjustment yourself, if your confident the other situation does not exist. Your water heater should have a little deflector shield on the gas line between valve and burner (typically immediatly after the orfice). Sometimes these will have to be slide front or backwards or twisted. The adjustment of deflector shield must be opened more to make the blue hotter flame to mak eyour heater operate at peak efficiency.

Good Luck

My model 501, 30 gal, LPG water heater only makes warm water, is this fixable, or should I think replacement?


Look at the flame and see if it's burning blue or yellow. And then see if it's burning all the time. If the flame is yellow and water heater does not make hot water, the thermostat may keep the flame going all the time and use up your gas.

Poor flame color means you should clean the burner or replace the burner. If water heater is exposed to trace amounts of some chemicals, like bleach or pool chemicals or wax, these chemicals get pulled into the burner and will shorten life of burner assembly and combustion chamber.

If the flame is blue and the water is not hot, then the thermostat is the best suspect. The thermostat is part of the gas valve. The gas valve has a copper tube that extends into the water and reads water temperature. If thermostat reads incorrect temp, then the gas valve needs to be replaced with gas valve from local plumbing supply of Lowes.

If the flame is blue, and it runs all the time, then your tank may have a layer of sediment between the flame and the water, and the sediment has caused water heater to become very inefficient.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

Now to answer your question:
You can turn up the thermostat dial located on front of tank.
Check your flame and how often burner comes on to determine where problem is.
You can buy a gas valve from Lowes for $65 or from plumbing supply and then replace >> you need a couple wrenches and pipe joint compound and about half a day.
You can clean the burner with wire brush and shop vac.
Remove chemicals from same room as water heater.
If the water heater has sediment build-up, then a new water heater is probably best choice.

You can do some things yourself. If the do-it-yourself steps don't work, then get a new water heater, and you know more about maintaining a water heater because you worked on the old one. Save the new water heater manual. Read the manual because it has ordinary information that will save you money long-term.

It has soot build up and doesnt get hot


the soot build up is evidence of another problem. Your fuel air ration is messed up. Is it possible you are at a higher altitude than the water heater was set for? When a water heater is installed at an altitude higher than 2,000' the manifold pressure on the gas valve has to be turned down. if that isn't done your wh will overfire and burn a rich sooty flame. You would expect to see a yellow flame rather than the ideal blue flame with yellow tips.

If this sounds like your problem then you need a proffessional to service the wh and reset the manifold pressure to the value in the owners manual for the appropriate altitude.

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.

G4-7 atwood water heater lights great, heats water but when it cycles the pilot goes out no hot water


Sounds like the burner flame may be too strong (jumping out from burner tube) . Some people think the louder the better, but that is not correct. When burner shuts down like that, it has a tendency to snuff out pilot as well. Adjust your air shutter at burner so that the flame is a nice blue, or with just a hint of orange/yellow at the tip. Whatever setting that keeps the flame solid from burner tube, and not a big gap between tube and flame. Signs of soot (black) up the cover, or side of trailer means it's running too rich, and you've gone too far thus needs more air. Keeping the flame blue but still right out of the burner, actually heats better, is quieter, and should eliminate that pilot getting snuffed out. Pilot should also be a nice blue flame as well. There may be a problem with positioning of the burner tube as well, but doubtful if it has been running well in that position before. Let me know what happens.
