20 Most Recent Dayton (3VU31) Oil Filled Electric Utility Heater Questions & Answers

Most likely Grainger. You might want to call them as their website can be a little tricky to find parts.

I assume this is a typical heater, with an on/off thermostat rather than temperature-dependent flame size controller. Make sure the burner is clean and the flame holes are not clogged. Also make sure the heat exchanger is clean, not loaded with ash or dust. Verify that you have adequate air supply to the heater (if the flame gets much larger when you have doors open all the way to the outdoors, you definitely have a problem, including a safety issue) and that the exhaust stack is not blocked. I've seen issues caused by bird or wasp nests in the vent plumbing. Check inlet gas pressure, and verify that the heater main gas valve is functioning. (If you have recently added another gas appliance, the piping may not permit adequate gas flow when both are running.) If you have your gas piped in from a utility company, you may have to ask them to verify adequate flow and pressure at the meter. Check the inlet to the gas valve to make sure it is not clogged with sediment (requires shutting off gas and removing the inlet plumbing from the valve).

This is probably a Tstat problem. Replace the Tstat and this will solve the problem.

A serial number is no good in such questions as it is just a numerical sequence of the number made. In your case number 5. The model number will get the fan. https://www.google.com/search?q=Dayton+heater+fan The motor number also doesn't help because that motor spindle can take a radial fan or a bladed fan. https://www.google.com/search?q=fan+blade+for+motor+A0416B2810 Or you can contact Dayton direct

Hi, Please remove the battery or disconnect the power source from the unit in order to shut the device off. Thank you.

Late to the show but might help others. Check for cracks in hoses. It sounds like a fuel draw issue. If ignitor is doing its job and, while motor is spinning, you don't see a mist of fuel coming out the nozzle then #1 hoses have cracks (1/4" I'd replacement hoses). #2. vanes on pump are not moving freely so pump pressure (about 5 pounds) is too low.

check safety circuit sail switch for fan and ignitor glows and check for cobwebs in burners
