Question about Vanguard Heating & Cooling

1 Answer

1st panel on Vanguard 22,000 btu ventless propane wall unit has overshooting flame causing strong exhaust-like odor in house. Has black residue coming out of top vents. No fan on this unit.Help!

Propane wall heater. We have a Vanguard model VP22001TB. 22,000 max btu. Probably installed around 1995.This propane wall unvented heater is installed in our home. It has begun to give off an odor more like automobile exhaust in the home and the flame on the 1st panel is overshooting up over the ceramic panel and burning onto the metal piece above causing black residue coming out of the upper vents. When we put it on the 2nd or 3rd panel it doesn't do that on those panels, just on the first panel. Is it possible the first panel needs to be replaced? We've been using this heater as our main heating source for 10 years. Most of the time we just have it set on panel 1.We have a heat pump, but prefer this heater. We turned it completely off for now. Would like some answers soon. Thank you.

Good thing that you turned it off as it is now not operating as designed and that makes gas dangerous
call an accredited gas fitter to properly diagnosed the problem and repair/ replace it

Why suddenly a strong odor of burning fuel when heater is operating?


Improper air to fuel mixture, way to rich.
Does this heater have the ability to adjust ratio?
if so, play with adjustment until odor goes away.

I have a blueflame probane heater ventless and when burning it has a slight smell. Is that normal for this ventless heater.


It depends on what it smells like. Initially, when the unit is installed it should be burned on HIGH for 45 minutes to an hour. Doings that, burns off all the oils and seasons the heater. Sort of like seasoning a cast iron skillet. After that, the newness odors should be gone. It's normal to get a whiff of gas when the burner lights or turns off. It should dissipate rather quickly.

Although Vent-free (ventless) heaters are very safe to use and are 99.5% efficient, their one drawback is that pick up strong household odors, like strong cleaning products, carpet shampoos, new paint or stain odors, strong cooking odors, etc and make them worse. That's why it's always best not to use the heater during or after painting, for at least 2 weeks. Although your nose may not detect the paint odor, the heater can and will make it worse. Also, always use your range's exhaust hood when cooking. Hopefully, it's the vented type and not one of do nothing recycling hoods.

Also, thoroughly cleaning the heater inside and out , at least once a season, will go along way in reducing odors and maintaining the longevity of your heater.

One other caution, do not burn scented candles and operate the heater at the same time. Scented candles soot anyway, but adding the warm moist, comfortable heat from the vent-free heater, will cause them to soot 50 times worse. Trust me, it's not the heater, it's the scented candles sooting.

Hope this helped explain some of the things that you asked about and more. If I can be of further help, please ask me through the Leave a Comment link.

You need to clean it out. Take the wall heater down and use a air compressor to clean out the gas system. Also clean the orifice out. Make sure that the chamber is clean and clear of spider webs and dust.

I have mold problems when using ventless propane gas wall heaters in a small rental house. The house is very tightly insulated. How can I solve this problem?


Air requirments for these units are 50 cubic feet of air for every one thousand BTU'S - if you are under this amount need to have fresh air into the room with a grill that has 1 square inch for every thousand BT'S.
