Why does my Vanguard 8000 generator pop the 40 amp breaker on the generator when I plug in the 30 amp cord into the generator .

There's either a short in the cord somewhere, or the breaker on the generator is faulty and needs replacing.

Pilot light too big, how do we adjust pilot light on a Vanguard KV1800?

There is no adjustment for a Pilot Flame's Length on a Vent-free Gas Appliance. However, if you're using Natural Gas and it's a Natural Gas Heater, the normal length of the pilot flame is 2 to 2 1/2".
If it's a Propane Gas Heater and the pilot flame is as long as previously stated, you probably have a pressure problem from your tank. Contact your Propane provider to have them check the pressure on their tank regulator.

When the heater has the pilot lit we can not turn the thermostat to light the elements.

Try pushing the control knob down sightly and turning it counter clockwise to ON position. If it won't turn, this usually indicates that the control valve has locked up. Turn the pilot off and wait 5 minutes, Relight the pilot and try turning it again, as described above. If it still doesn't turn easily, the Control Valve will have to be replaced. It's not an inexpensive part, as it's the heart and brains of the heater.

Also, DESA International the manufacturer of your Vanguard heater is no longer in business. However, some parts are still available. Do a Google search for Vanguard Vent-free Heater Parts and you may have some success in find it for your specific model number.

It's rare for a control valve to lock up or fail. It's usually caused by someone trying to force the control knob to turn with a pair of pliers and usually in the wrong direction. Which breaks the plastic gears inside the control valve. I'm not saying you did this, it's just what usually causes it.

Vanguard wall heater pilot will light but when to turn on heat it goes out. Thermocoupler??

This is a very good possibility and depending upon the year they may call this part a flame generator. So ask for both when purchasing. Before you run out and purchase this take five minutes and try this, I use steel wool or light grit sand paper and clean up the bulb end of the thermocouple then place it top center of the flame as this is the hottest area of the flame, now with a small wrench check to see that it is tight in the gas valve. Now try lighting the pilot and then the furnace. Some times a simple cleaning and tightening can cure this problem. If not now you can go and purchase a new one.

Have a model up26t serial#010782007,lights and burns good for 10 minutes or so. Then you here a click up in the control area and it shuts flame and pilot light off. If you wait a little while you will hear...

The manufacturer has a website ( ), they list part distributors on that site this should help you in your search. It should like you need to replace the thermocouple or the ODS pilot assembly... this is the most common problem with these units. I think your model must be a VP26T if is a Vanguard unit?

Pilot on logs won't stay lit

Hold pilot button longer. if this doesn't work your Thermopile has gone bad and will not generate enough Millivolts to keep gas valve pilot open. A new thermopile will generate 750 millivolts. It cost less than $20 dollars but is difficult to replace. You should call a certified technician. They will charge you about $100.00
