Question about Rinnai Desa Vent-Free Infrared Gas Heater: Vent-Free Infrared Gas Heater(18,000 BTU)

My ventless propane heating stove shuts off by itself

I have a Vanguard ventless propane stove model # svyd18pr. It has an ODS pilot asembly, I have more than enough square footage of space for the BTUs of the stove.
The pilot will stay lit for days... But when I turn the stove on it stays on for maybe an hour or less, sometimes only a few minutes then flutters, clicks and goes out. If I try to light it again soon it stays on for less than 5 minutes and goes out. If I wait a while it will stay on longer, but never more than 20 minutes to an hour or so. I vacumed the inside of the stove and blew out the air holes of both the burner and the pilot with canned air. I want to know if there is anything else I can try, or do I need to replace the pilot assmbly.

    Hi Paul

    One clarification is that the stove is not a Rinnai. It is a Desa Vanguard vent-less stove. With a log set. (I didn't have that option when I had to choose a product in order to ask this question, so I chose DESA Ventless gas). I don’t know the age but I would guess 8 – 10 years.

    How old is the stove? Rinnai is a good quality manufacturer and they make all of their own parts. The age will help more.

    Thanks Paul

If you cleaned it already, then it could be the gas pressure. If the gas pressure is fine, then you most likely need to replace the ODS pilot. The part # you need is PP225. You can order it from Master Parts. You can find them online at or call them toll free at 800-466-1446. I hope this helps.

I have a Vanguard wall heater model VN18TB that will not stay lit and the electric igniter won't work

The ignitor is battery operated. Remove the button and replace the AAA battery wit the (+) going INTO the body (-) against the button.

The heater has a pilot with an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS/pilot is a required feature for vent-free room heaters. The ODS/pilot shuts off the heater if there is not enough fresh air. If the heater will not stay lit with plenty of fresh air available - this may be faulting. Likewise, a mispositioned thermocouple will not sense a flame and fail, too.

A link to the heater manual is below:

Your DESA/Vanguard Vent-free, Blue Flame Heater has a pilot assembly that is equipped with and Oxygen Depletion Sensor (ODS) . When this becomes clogged with dust, lint, spider web, etc, the pilot may light and burn for a few minutes, but will soon shut down. As the ODS senses that there is not enough oxygen for safe combustion. This mimics a faulty thermocouple. A good indication that the pilot is dirty, is when the pilot flame curls upward and looses contact with the thermocouple. Cleaning the pilot and it's ODS with canned air and a straw nozzle (like you clean your compute with) should solve the problem.

To further help you, I have included a link to the Owner's Manual for your Model, as well as a link to how to clean the pilot & ODS

The thing with these is over the summer months when they are not in use they get dust inside the ODS safety pilot. When that dust gets in there it cuts down on the oxygen inside and the safety simply shuts down because it was designed to do that. What you need to do is flush the pilot and allow it to dry. I use a product caller but you could use shop air or even a soda straw to blow out the pilot. I used to sell these thermocouples for ODS systems and they are not cheap. Most times they do not solve the problem either because the pilot is dusty. A brand new one won't solve your problem and a cheaper thermocouple don't work on these. More HERE

Here is the whole thing for $52 not a bad price
The thermacouple alone for these cost nearly as much by itself.

This sounds like the connection for your thermocouple has lost a good connection.

Change from natural gas to propane

You could do it but it would be very expensive. You would need to change the ODS pilot and the gas valve itself. I am not sure even then it would work correctly. These are not conversion ready.

Pilot light won't light on ventless fireplace

Ventless Gas logs, Vanguard, VS30PR. Propane gas
Pilot light stays lit various times, sometimes for several days then other times for a few minutes. Lights best when temp outside is below freezing. Pilot flame appears to receive too much air. How do you adjust the pilot flame? Is this done using two screws marked A & E? Do you have suggestions?

I have Legacy ventless propane heater 15,000btu.

Try to take pilot assembly apart and clean real good. This will work most of the time. If it does not work for you, you will need to replace the gas valve. It's expensive but I'm about positive that cleaning it will fix it. Gas burns dirty and after a couple seasons a scale builds up that causes this problem. It's pretty common and nothing to worry about after it's cleaned. Good luck.

Burner keeps going out

It might be the ODS Pilot Assembly. It could be clogged with dust or lint.
It might be low gas pressure.
It could also be the pressure regulator.
