Water Heater Blowout

[porterwolf]

Our 14' Grey Wolf has had a consistent problem with the water heater. Several times a weekend I find that we have no hot water. I go out and the pilot light is out, relight the darn thing and it usually lights fine. I found this week end that when I light the pilot and turn the knob, I hear the valve click, I can hear the gas, and wooof! The flame shoots out of the fire chamber and snuffs out the flame including the pilot light. Any ideas???

Pilot Light System not Electronic?
Check the ignitor gap, check burner tube has no spider/webs in tube. If you have the proper tool; a manometer check gas psi ( inches of wc) is correct. All connections are tight.

As for you water heater going off several times. there is some type of obstruction that is disrupting the fuel/air mixture. check all piping areas.

When you light the pilot light, leave the knob (with you holding it) in the same location ('pilot lighting location) for a few more seconds. That allows the end to heat up and then the pilot will stay on when you 'slowly' turn the knob to the on position. your pilot light should then stay on fine.

I am no expert.... I would first assume dirty unless someone has been working on it and moved the pilot assym away from the path of the LPG... then maybe.

Cheap check is to inspect and blow it all out. Dirt daubers, spiders and bugs are your enemy.

Possible thermocouple fault. Check position of tip.
