Question about Dayton 511 Utility Heater

1 Answer

Dayton 150,000 btu that won't stay lit

It is getting fuel, I cleaned the air filter, it sprays fuel and you can see the spark but won't lite

I am having the exact same problem with my Dayton 150,000 BTU. There is fuel, spark and the fan runs but it will not light up. I took the cover off and it would light... but I think that is because the fan was not forcing as much air across the spark and fuel. Seems like the fan is not allowing it to start.... Suggestions?

If...the air pump pressure is right, the ignitor glows, the fuel is hitting the ignitor, then the unit will have combustion......unless.....
  1. there is an air leak on the pressure line
  2. there is a vacuum leak on the fuel line
  3. there is a leak at the nozzle adapter
  4. there is a restriction either in the nozzle or the fuel filter
  5. the nozzle is worn and is spraying fuel rather than fogging fuel

Wat the hell is wrong with my dayton heater?170,000 btu oil fired...wont stay runnin?on shut down puffs like a mutha....


Most use a spark plug to ignite fuel it could need cleaning. You also could have water in fuel or dirt
check and clean ignitor/spark plug clean fuel line and nozzle, drain and clean tank Check for water in fuel by tilting unit to have a low corner siphon fuel from that corner after 1 hr inspect for water.

DAYTON 210,000 BTU OIL-FIRED HEATER WON T LIT UP


You write "FUEL SPRAYING AND FAN WAS WORKING"

If the fan was working, but the fan is not working now after replacing the whole kit, then something was installed incorrectly during the installation, possibly the rotor gap or rotor thickness is not correct or vane/vanes installed 90 degrees off.

30'000 btu spark style will not lite


  1. clean the fuel filter
  2. clean the nozzle
  3. set the air pump pressure.
It should fire off, unless you have developed an air leak, worn nozzle, bad fan, or a motor that is not turning rpm's.
