Top 20 Dayton 2YU44 Electric Heater Questions & Answers

Hi,
Here's what I think but you will have to check it out...
The fan motor in the 39 heater is a 120V fan there fore it cannot be hooked to the 240 which potentially could have the high (wild) leg as one of the fan legs...
The 240V 36 unit probably has a 240v fan motor....
Now if you were to make sure that the leg that fed the motor was a 120V to ground leg then you will be okay...
Hope you understand where I was going with this...

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).

Help in the link, but you LPG Gas fitter should know all this. All gas installations must be done by a gas certified technician. https://www.google.com/search?q=Dayton+Furnace+3E847+LPG+Pilot+orifice+size ..

recheck wiring and unit circuits motor is in

check the igniter circuit--gas feed --thermocouple --fan-vent safety

I'd give Grainger Supply a call

answer is unattainable since it is unknown what the previous owner has done to modify it ---you can try to get a wiring diagram [none on line ] and use a meter to check unit for modifications or a failed component -----or have a repair shop check unit

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.

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

look for a bad gas solenoid valve: Spark is working, no flame = no gas getting to the igniter. Do you have gas? Is the main valve open?
