Sounds like you've solved the problem. The lack of circulation to the unit is causing a draft-like noise? "Just add more air"

I have a John Wood one pipe power vented hot water heater. The model number is Jw840nvh-fv-04. Recently I've been smelling products of combustion coming out the top of the tank where the vent is


1) Copy following link for troubleshoot resources by type of gas control valve, Venting resources, and pro water heater forum:
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html
http://www.thetankatwaterheaterrescue.com/forums/forum3/

2) This odor can indicate incomplete combustion due to lack of air supply. Get more fresh air to unit. Check that flame is clear blue color. John Wood is American/AO Smith product so air intake screen is located on bottom of unit. Use mirror and flashlight to inspect. Clean with compressed air ad or feather duster.

3) Jw840nvh is 40 gallon natural gas. Natural gas is lighter than air and rises upward, unlike propane gas that is heavier than air. Install gas detector at height correct for type of gas.

4) For safety, install CO carbon monoxide detector

5) Review product manual for correct vent lengths and diameters.

Propane water heater high limit switch keeps kicking out


1) What brand and model water heater?
Copy following link for troubleshoot by type of gas control valve.
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent

2) Clean air intake screen using compressed air or feather duster.
With AO Smith, craftmaster, state, reliance, american, kenmore, whirlpool, the air intake is located on bottom of heater. Rheem, richmond, ruud, GE, Bradford white, the air intake screen is located under combustion parts.
Water heaters today require plenty of fresh air. If air intake gets clogged with dust, then combustion byproduct moves up pipe too slowly for amount of fuel being burned, and this overheats combustion chamber.

Any brand of water heater better than the others? Currently have a Rheem gas 50 gallon


Short answer:
6-year Whirlpool from Lowes, 6-year Kenmore from Sears
Both are same brand. Offer 10% less than price, get store coupons.

Reasoning:
#1 Warranty.
Warranties are same across all brands. First year parts-tank-labor are covered, and afterwards parts-tank are covered for original homeowner and non-commercial installation when installed by instructions shown in manual.
The math shows: shorter warranty has greater percentage of full coverage.
6 year 9 year 12 year?
Only difference is anode rod diameter, or longer-warranty tank may have 2 anode rods.
You can convert 6 year tank into 12 year or 15 year by inspecting anode each 1-3 years, and maintaining tank as shown in product manual.
http://waterheatertimer.org/Replace-anode-rod.html
http://waterheatertimer.org/How-to-install-gas-water-heater.html

# 2 Don't buy tankless.
Don't buy gas or electric hybrid.
These do not save money overall, and do not last longer than ordinary tank heaters, and they are expensive to buy and maintain and repair.

# 3 Ordinary Whirlpool gas water heater from Lowes is inexpensive and can be maintained and repaired by homeowner.
Air intake is located on bottom and can be cleaned easily.
Set 3-legged water heater on bricks so air intake can be inspected and cleaned easily.
Whirlpool is made by AO Smith parent company. Other brands made by AOS are Reliance, State, American, Craftmaster, and Kenmore.
Service manuals are posted online, parts are designed for quick, ez replacement.
Installation manual shows how to perform maintenance.

# 4 Avoid Rheem.
Rheem makes Reliant, Richmond, Ruud, and GE
Air intake can only be cleaned by removing combustion parts. Combustion parts are held in place with tamper-proof screws.
Service manuals are not available online.
Installation manual does NOT show how to perform maintenance, and says that customer must call for service.
Rheem does not offer better product that somehow needs specialized treatment, they just want customers to buy service from brand-loyal plumbers.

# 5 Bradford White makes good heater.
Usually these are more expensive and not available except thu dealers who might require pro installation for warranty coverage ... maybe.
Are BW made better? Warranty is identical to other brands.
Must remove combustion parts to clean air intake.
Parts are ez to replace, but they might not sell parts direct to homeowner.
Service manuals are available.

# 6 Insulation thickness.
Does not make much difference with current price of gas.
If you pay $400 more for a tank with 2" insulation instead of typical 1-1/2", then payback can be 15 years or more.

Have to keep lighting water heater


Clean air intake. Change thermocouple.
American Standard appears to be Bradford White or Rheem product from the one image that appears on the AS site.
Air intake located on side of unit funnels air to arrestor screen located under the combustion burner.
Remove burner and blow out screen with compressed air.
If this is Rheem product, then also inspect for broken glass vial that indicates high-temperature FV event, which might also require other parts to be replaced.

Pilot light won't stay lit on new water heater


1) Get more air to the water heater and see if problem continues.
2) Read the following pdf-s for things that might apply to your situation.

3) Read pdfs above first, and then Add a comment with missing information below, for possible do-it-yourself help.
Does this water heater have a blower?
Is gas valve electronic? Or does gas valve have a dial?
If gas valve is electronic, have you checked outlet with circuit analyzer?
Did pilot light work correctly for a while? If so how long?
Where is water heater located? Hot attic? Closet? Garage? Is area dirty and dusty? Has air intake been cleaned?
What color is pilot flame? Clear blue or yellow-or-orange?
Have you inspected inside of combustion chamber for dripping water?

I have an old whirlpool gas water heater and the pilot will not stay lit.


Suspects include bad thermocouple, thermocouple slipped down and not in pilot flame, dirty combustion parts and pilot tube, dirty air intake, backdraft caused by other vent fans pulling air down water heater vent, water dripping down vent because of poor venting, air in gas line, low gas pressure, bad gas control valve, hot attic environment, tight house not allowing enough air:

Had three 50-gal American Standard water heaters installed Dec. 2009 Two upstairs in attic, one downstairs at ground level. Attic location used because heaters being replaced were up there. Upstairs...


Plumber is right.
Problem is not amount of air in attic. Problem is how hot the air is.
Oxygen molecules separate apart in very hot air and pilot light goes out since there is not enough oxygen density to support combustion.
http://waterheatertimer.org/images/Water-heater-in-attic-800.jpg
http://waterheatertimer.org/pdf/Attic-Ventilation-and-Pilot-Outage-in-Gas%20Water-Heaters.pdf

More ventilation is needed.
Plumber is not ventilating expert, and not responsible for attic ventilation that builder failed to install. Plumber should do a survey of location before installation to make sure gasoline vapors are not stored nearby, but summer attic ventilation is gray area until more general-public folks become aware of problem. Hotter summers temperatures will spread that information.

Hire local home center to install roof vents AND soffit vents.
Note: You also need soffit vents.
Remember a vent on the roof is like sucking air out of a coke bottle. The roof vent is no good unless air can also enter the attic from another vent located in the soffit.

Another solution is electric water heater for very hot locations.
Or install solar-assisted water heater.

Is the American Standard G50T 2-3-6 a good water heater? I have trying to find stuff about them on Google but I keep getting results for american water heaters not american Standard and the reviews are not...


Generally, they are a your normal low end hot water heater. I have seen American Standard units last up to 20 years (like mine) with not problems, and I have seen them not last three years before the tank ruptured.

We have more calls on the Rheem and Brandford Whites than American Standards as far an minor problems.

Pros: Cheap; reasonably reliable; parts readily available.
Cons: Not energy efficient; tank quality - flexible.

When mine goes would I replace it with another American Standard? No, I would install the Bosch tankless water heater.

Water heater burner assembly and combustion chamber probably needs clean and maintenance.
I suggest calling sears service 1-800 469-4663 or plumber.

I'm on Sears/ American/ Rheem/ Reliance etc gas water heater websites most days, and read gas water heater manuals continually.
http://www.sears.com/shc/s/search_10153_12605?keyword=kenmore+power+miser+9+40+gallon+gas+water+heater+gas

Most people don't fix air conditioning without knowledge going in, but people think water heaters are simpler, because water heaters were simpler a few years ago.
Today, gas water heaters require testing equipment, and specialized tools, plus replacement parts.

Possible problems include: Improper fuel-air mixture, dirty air intake, venting problems, gas control valve problems, air in gas line, low gas pressure, dirty combustion parts, Water condensate dripping on burner, chemicals stored inside same room. Service technician will review all these things during troubleshoot, and you can watch technician and glean information for keeping water heater working longer than warranty.

If repairs are going to cost more than $400, then install new gas water heater yourself same day:
