Gas doesn't seem to be flowing

I purchased this heater second hand - I have fitted a brand new regulator and gas hose - gas is flowing as far as the burner assembly but I cant hear or smell gas flowing to the pilot or the main burner. Is there a section of pipe between the gas hose and the burner that could be missing? Does anyone have a diagram of all the parts - exploded view?

I have a Jayco pop up with an Atwood water heater, serial # 37C14U-5. My problem is two-fold. The water heater pilot doesn't stay lit after initial run, and propane is leaking out of the vent on the...

Leaking propane is red flag #1 and fire hazard.
Immediately update your insurance and then turn off gas.
If pilot is not staying lit, then gas leak can be cause of pilot problem since pressure on the line is reduced.
Other causes include bad gas control valve, air in the gas line, bad thermocouple, burner parts need cleaning, or all the above.
After fixing leak, replace thermocouple, clean combustion chamber and burner parts, and bleed gas line to remove air.

I need to remove the burner to check the safety device. How do I remove the burner?

You need the manual for your specific Rheem product, which shows periodic maintenance steps needed and will sometimes show diagrams.
Open following link, click on same-similar product, when page opens, click tab that says Specs/Docs, download Use and Care manual:

The instructions will probably suggest you call service technician do the work.
After all this is a gas appliance, and not really a first-time learning opportunity. One kaboom is a lot more expensive than watching what the service technician does so you can repeat it later.
If cost of parts and labor is higher than $330, then it might be cheaper to install new gas water heater that you buy from local box store.

As a general non-specific guideline for cleaning burner.
Some water heaters have a gasket-seal where pilot and burner tubes enter combustion chamber. You might need this gasket replacement on hand in case old one breaks.
Other combustion covers have tamper-resistant screws that signal a service technician should do the work.
1) Take photos of all parts and areas so you have a record of how it looked for easy reassembly and relighting.
2) Turn off gas to water heater. The gas valve handle should be perpendicular across the gas line to turn off. The gas valve handle is parallel with gas line when gas is ON.
3) Using wrench, loosen tubes that attach to bottom of gas valve control. Notice tightness of each when loosening. The thermocouple is finger tight plus 1/4 turn. The other fittings are snug to prevent gas leak. Note which fittings have sealant on the threads, and then use yellow teflon tape on those fittings when reassembling. Test gas lines for leaks using liquid detergent mixed with water. Soap bubbles indicate gas leak.
4) Lift burner out of combustion chamber.
5) Clean burner and combustion chamber with wire brush, and you can use mild detergent with a bit of water.
6) Use a burner brush to clean out burner tubes, and use air pressure to help remove particulate. Remember, obstruction as small as a cobweb inside the tube can cause the water heater not to operate.
7) Finish up using vacuum cleaner, reassemble parts, and light water heater using instructions printed on side of tank.

1 Answer

I have a 40 gallon rheem water heater for a mobil home that is leaking from the top.

If water heater is leaking, then open following 2 links to avoid tank rupture and troubleshoot leak:

Open following link if you want to install your own gas water heater:

40 gallon electric heater at Lowes costs 207, and is easy do-it-yourself using same basic information shown in link above for installing gas heater, except less work.

To have gas water heater installed, can run $2-300 for installation plus cost of heater.
40 gallon natural gas water heater at Lowes starts at $300+, and tanks with longer warranty cost more and last longer.
Trailers require specific type of gas water heater, so be sure to request correct model.

If you maintain the tank: keep chemicals out of same room as gas water heater, attach bare copper ground wire between hot and cold pipes, flush tank each 6 months, clean gas burner each year as shown in manual, read the manual entirely for specific information about your model, and inspect/replace anode rod every 2-3 years then basic 6-year tank can last much longer.

The burners on the left side of my burner tray do not come on? Getting out the burner tray seems difficult. What should I do?

Has water from rain or sprinklers gotten on the heater? Sounds like one of the following:
  1. Plugged burner orifices
  2. Plugged burners
  3. Low gas pressure
  4. Bad gas valve
  5. Poor venting
Your best bet is to remove the burner tray. It really isn't that difficult. Follow the owners manual. If you do this yourself, be sure to leak test all gas fittings.

Gas hot water heater will not automatically heat water, i have to manually start the burner to heat the water

Sounds like you have a bad thermostat. You can change the thermostat, but if the heater is more than 8 or 10 years old you might be better off to replace the entire heater. Thermostat replacement is easy:
1 turn off the gas 2 drain the heater 3 unscrew pilot, main burner, and thermocouple lines from bottom of thermostat. 4 unhook gas line from thermostat. 5 unscrew thermostat from heater tank. Use pipe sealer when you install new thermostat, and gas line fittings. burner and thermocouple lines seal on a taper seat and do not need sealer. after reassembly check for leaks with soapy water, not a match, light the pilot and turn up the temp. The heater may sweat quite a bit while it is heating up the first time, this is due to the cold water on the inside and the fire on the outside. some water may drip in the bottom of the heater and you might think you have a leak, but let it heat up completly, if the water is still dripping after the tank is hot then you need to find the leak.
