    Thanks for your suggestions but the heaters are not new ones nor have they been in storage. They have both been used quite frequently even in the summer months. My office has a lot of drafts and is cooler than the other offices. Your suggestion of dust on the heater coils however could be the answer. The heater emits an odor that we all think smells similar to fish. Any further suggestions?

    I have the SAME exact fish smell whenever I am using my heater. It still works great but, it smells so bad.

I would blow out the unit with canned air or better yet an air compressor. when it is cooled down possibly wipe the coils as best you can. Also, when blowing it out, blow inside the motor assembly as dust could be in there also.

Is this a realtively new heater or just come out of storage? Chances are, if it hasn't been run in a while that it is just burning off some of the dust on the heater coils. Or possibly some of the chemicals used during the assembly of the product is risidual on the coils. Let it run for a few hours while keeping a close eye on it. I'm sure the smell will go away eventually. Keep an eye on it because if I'm wrong it could pose a potential fire risk.

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.

We have 3 unvented gas heaters that have worked fine. turned them all off while painting work was being done. turned them all back on and the smell of the fumes makes us turn them back off. i took them...

Becky, heaters are picking up the fresh paint smell and making it 50 times worse. Although you may not be able to detect the odor, the heaters are picking it up. You need to turn the heaters completely OFF (pilot lights too). Wait at least 2 weeks before trying to use them again. If you have some good, warm days that you can open some windows, that will help to get the paint odor out of the house.
The odor is really not in the heaters, it's still picking up the fresh paint odor that your nose can't detect.

In addition, if you use commercial carpet cleaning products, the heaters should be turned OFF before cleaning the carpets and remain OFF for several days.

Vent-free Gas Heaters are very, very safe & efficient. But, because they use interior air for combustion, they pickup any strong odors and make them worse. Also, never burn scented candles and operate the heaters at the same time. Scented Candles soot anyway, adding the warm moist heat from the heater(s), will make them soot 50 times worse.

This should solve your problem.

I have a 30,000 btu ventless mr heater for two months it has run with absolutely no smell,the other day I did some wood staining, now the heater has a strong co2 smell is their any way to clean the heater...

Sure is. Never operate a vent-free gas appliance (not even the pilot light) while painting, staining, cleaning carpets, etc. It picks up the odors and will not burn the odor off, because the odor doesn't get in the heater, it just makes the odor worse. You will need to turn the heater off and not use it, until ALL of the odor from the staining have completely dissipated . It may take a week or more, even though you may not be able to smell the odor from the stain, the warm moist air from the heater will activate it again. If you get a warm day soon, open a window or two and let the fresh air in. That will help dissipate the odor. But, allow a week minimum, before trying to use the heater again.

Oh, by he way, that wasn't co2 you were smelling. co2 is dry ice. It has no odor. Just like co (Carbon Monoxide) it has no odor. You were smelling the fumes from the stain. Just 50 times worse.

Good luck to ya,

I have a reddy heater 100 pro it stinks when it is going and burns my eyes

If you are using it inside, in an area that is not well ventilated, that is the problem. In addition, if this heater is in a work area and there are paint or stain fumes or anything similar, the heater is picking up those fumes and making them 100 times worse.

Also, is the heater has not been cleaned and service regularly, this also could cause the odor, due to incomplete combustion. Also, how old is the gas in the tank you're using. Old LP Gas can also cause the odors.

Those things listed above, are all things that can cause the problem you described. Resolving those should take care of the odor problem.

Contact your Gas company tell them you have a foul smell coming in when you turn on the heater. They typically wont charge for a technician to come out and inspect the heater for you.

My reddy heater was running and ran out of fuel at which time it gave off a foul exhaust. Was this exhaust carbon monxide or just the sulfer smell associated with kerosene?

probably both and unburnt fuel also. when the unit ran out it still pumped a small quantity of fuel into the hot burner chamber where it turned to smoke and was expelled. carbon monoxide itself is odorless and what is normally referred to as c. o. odor are unburnt fuel products, some of which smell pretty strange.

RINNAI Heater 1001FT Gas heater; was wondering if water required?

It shouldn't give an odor at all unless it hasn't been run a lot or cleaned. Rinnai recommends blowing compressed air through the front grates once a year. The pan is to catch condensate from the venting system. Hot flue gases contain moisture, which is a byproduct of burning propane. When this hits anything below 212 degrees, it will condensate and collect in the pan. The heat from the unit evaporates the water, thus making it a good system of condensate disposal. However, additional water can be added daily if you have problems with dryness in the air. The only other thing that can cause a bad odor is a compromised heat exchanger. You should have it checked, and if you don't already, have a CO detector in the room

Heater will not operate!

did you take it apart to see if the switch is good or the thermostat was functioning?  without looking inside, other than saying it don't work, isn't going to solve anything.
