Dayton 3VE52

Basics

• A Portable Oil Fired Space Heater
  • Often called “torpedo heaters”
  • Electric Forced Air

Repair

• This has (Constand?) Spark Ignition, Photocell Based Flame Detection, and Vane Pump Air Compressor (~10 PSIg Max supposedly) based Siphon Sprayer for fuel delivery/atomization
• Check for Fan/Spark, if both are good it’s probably a Fuel and/or sensor issue
• Air Filters+Hoses can be Dry Rotted
• Frontmost Hose is Air, Rear Hose is Fuel-In
