- 120630-01 Pilot ODS for Vent Free Natural Gas Wall Heaters by DESA, Glo- Warm

I used this in my natural gas, non-vented, logs. The pilot burner wouldn't keep a flame going so I used the thermocouple and igniter with my old pilot burner. This new pilot burner seemed to be sized for propane gas. I am a trained, licensed, gas appliance servicer and have the professional knowledge to make these adjustments. I personally recommend you hire a professional for these type repairs.

Worked great for my Mr heater propane infrared wall mount heater.

First, mine is a Comfort Glow and my issue was the pilot was not igniting from the igniter and there was corrosion build up on the flu end after 23 yrs. Thus when I manually lit the pilot, it was half yellow with an up sweeping flame. If you have the old manual, you'll see this is not how it's supposed to be. It's supposed to be a straight, primarily blue flame across the thermocouple. Both pics are after install. I had the identical problem Jared did as I titled upon install of the new parts. Even though the provided orifice appeared to have a large enough hole, it did not provide proper fuel to the pilot. The pilot would come on only about an inch, then it would go out if I left it alone for a bit or when I tried to apply fuel. So as Jared said, simply swap it with the old orifice and the flame came on as it should and I now have properly functioning space heater to include pilot lighting. I only gave it a 4 star simply for the modification swap needed, other than that it would of gotten a 5.

nice

I bough this for my Sister-in-laws room heater. This would not work in her heater. Now Viefow will not allow me to return it or get a refund. No where in their description does it say "No allowable refund". Now I am stuck with a part that doesn't work and a heater that doesn't work and I have to find the correct part or have a service call to a repair company, leaving her house cold during the winter. Thanks a lot, this company is a waste of time and money.

I received this unit today and installed it which is a straight forward process. The pilot light on this unit did not allow enough gas thru to stay lit or heat the thermocouple enough to operate the main valve. I reused the old pilot because all I really needed was the thermocouple which so far appears to be working. I read other reviews about this item that had the same problem so there appears to be a quality assurance issue with the pilot light portion. So if you buy this unit and only need the ignitor and/or thermocouple you're in luck--I think-- but it's a hit or miss on the pilot light. I'm adding this after further study. I believe this unit has an orfice sized for propane rather than natural gas. Propane is delivered at a much higher pressure than natural gas thus requiring a smaller orfice. For natural gas, pilot orifices run from .014 to .026 and for LP from .006 to .013. Most natural gas pilots on heating using thermocouples are .018 or a tad larger that 1/64" (#77 drill bit). Quite a difference in orfice size hence the low flame.

Pilot assembly was exactly what I needed.

Part was an accurite fit and easy to install.
