It is very common to find spider webs (or even mud dauber nests) inside the burner tubes on RV's and trailers. This will cause the burner to burn sporadically at the air adjustment. If you have a small brush or flexible item that can get in there and clean it out, then see if that solves the problem. You may also try adjusting the air shutter for the perfect and quieter blue flame. Douglas

Furnace and pilot will not stay lit


The tube is gas supply for pilot. You have to make sure the thermocouple is in the flame at least half way and make sure its tight in the gas valve. There should be a small silver plug on the gas valve near the pilot supply tube. You can pop the cap and adjust the height of the pilot flame a little. Can you tell if it has a flame rod in or above the flame? If it does You can remove it and clean it with steel wool.

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.

o light the pilot on a standing-pilot (always on) ignition system, follow the lighting instructions located near the control. Otherwise, try these steps: Light the pilot:
  1. gasfurnace1.jpg Press and hold the pilot control knob to start the pilot. Set the control knob to the pilot position. Hold a long match under the pilot gas port.
  2. Press the control knob; the pilot should light. Hold the control knob down until the flame is burning brightly (about 30 seconds). Release pressure on the knob, and turn it to the on position.
  3. If the pilot goes out when you release the control knob, try relighting, holding the control knob down longer. If the pilot again goes out, check the thermocouple (below).
Adjust the pilot:
  1. Remove any cap covering the pilot adjusting screw on a combination control.
  2. Turn the adjusting screw counterclockwise to increase the flame or clockwise to decrease it. It is correctly adjusted when the flame envelops the thermocouple bulb by 1/2 inch and appears dark blue with a small yellow tip.
Test and replace a thermocouple:
  1. Hold the control knob to pilot and light the pilot as above.
  2. Unscrew the thermocouple fitting with an open-ended wrench.
  3. Set a multimeter to the DVC (lowest voltage) scale.
  4. Clip one multimeter lead to the end of the thermocouple tube nearest the pilot and the other lead to the fitting on the other end of the tube.
  5. If the multimeter shows a reading besides zero, the thermocouple is functioning. Replace the thermocouple tube.
  6. If there is no reading, you will need to clean or replace the thermocouple following steps 7 through 11.
  7. Release the control knob and shut off the main gas valve on the gas-supply pipe that leads into the burner. Shut off power to the burner at the electrical service panel .
  8. Remove the thermocouple from its mounting bracket.
  9. Wipe the combination control clean and install a new thermocouple, tightening it by hand, then give it a one-quarter turn with a wrench.
  10. Insert the thermocouple into the pilot bracket, being careful to not crimp the tubing.
  11. Turn on power to the furnace and relight the pilot (above).
Adjust an adjustable burner air shutter:
  1. Set the thermostat to its highest setting to keep the burner running. Once the furnace has heated up, remove the burner access panel and loosen the locking screw.
  2. Open the shutter by turning it to the right until the blue base of the flame appears to lift slightly from the burner port surface. Then close the shutter until the flame reseats itself on the surface.
Clean removable burner tubes and ports:
  1. Shut off gas and power to the furnace.
  2. Unscrew or loosen and remove the tubes from the supporting bracket.
  3. Carefully clean the tubes with a brush or vacuum, making sure not to damage the burner ports.
  4. Use a stiff wire to clear any debris from clogged ports.

If there is no heat, check the electrical service panel for a burned fuse or tripped breaker. Relight the pilot light (see below).
If there is not enough heat, adjust the burner air shutter (see below); and clean the burner ports (see below).
If the pilot light does not light or does not stay lit, clean the pilot orifice carefully with a toothpick, test the thermocouple and replace it if it is faulty (see below).
If the flame flickers, adjust the pilot (see below).
If there is an exploding sound when the burner ignites, adjust the pilot to a higher setting and clean the pilot orifice and the burner ports.
If the burner takes more than a few seconds to ignite, clean the pilot orifice and adjust the pilot light.
If the burner flame is uneven, clean the burner ports. If the burner flame is very yellow, clean the burner; open vents in the furnace room to provide more air; adjust the burner air shutter.

You are correct, there should be no flame after it shuts off. Pull the + wire off at contacts as well and see if flame remains, if it does, the gas valve is faulty (leaking by) and should be replaced.

Sounds like it. Before replacing gas control, try removing thermocouple connection at valve and spray electrical cleaner in there and blow out with compressed air after, being careful not to get it in your eyes. If no electrical cleaner, try WD-40 and blow out after. If you twist up a piece of fine steel wool and insert in there as well and try to spin/twist it to clean contact inside may help as well. Blow out goo after and re-install fitting and try again. If that doesn"t work, replace gas control.
P.S. Highly recommend certified experienced tech perform this control valve replacement if necessary.

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.

Hi: I have a atwood-6-gallon heater, the pilot works well but when I try to switch over to the main burner the pilot goes out time after time --- only used once. Thanks in advance Jim


This can be caused by a number of problems.
1. How long has the pilot been lit before you turn it to burner? It needs to warm up the end of the coupler. When you push in on the knob to light the pilot, hold it in for a while after the pilot lights. This allows more gas/hotter pilot flame to warm things up.
2. How fast are you turning it to burner? You need to do it really slow. The gas is under pressure and can blow out the pilot if you do it too quick.
3. Is there a blockage in the tube? Lady bugs, spider webs, etc. can cause a blockage and this problem. It's pretty common. (A long pipe cleaner will clean it out in a few seconds.)
If all of these fail:
4. It it getting too much/too little air? Check the air gap in the end of the tube. (Also called air manifold)
