Fisheyes from propane heater

The other day I fired up a propane salamander in my booth to get it warmed up.

I sprayed a seal coat of epoxy shortly after that and noticed some small sporadic fisheyes, which is something I never get.

Could these be from the propane combustion by product in the air?
 
i doubt it. i have not used a propane salamander heater in my booth but i do use a 220k btu oil burning salamander in the booth and i have for almost 20 years on a daily basis. i would think an oil burning one would be worse for fish eyes than propane but i could be wrong. in any case, over the years i have had many flame outs between coats where the heater just fills the booth with white smoke and it never causes fisheyes. i turn the fan on, clear it out and go back in and spray the next coat like it never happened. with that said, never rule anything out.
 
I agree with Jim. I have used a propane torpedo heater several times, in a small building sealed up with little ventilation. Only issue I ever saw was due to not paying attention and the output overheating a spot on a panel. I would run it before spraying, shut off while spraying, then turn on after. Should note this was before I found SPI. So can’t rule it out but think it’s unlikely.

thats good to hear. my window for paint is rapidly dwindleing. its salamander or wood stove here and i was thinking either a bad idea. i cant run the stove and exhaust fan the same time either.

ive always wondered if spraying while my neighbors burn their trash would have any affect...sometimes they burn alot of trash...and im down wind.
 
Always used one myself here never a problem. Just wish fuel was cheaper. Or I could utilize some of my drain gas or used oil lol.
 
I have used a 150,000 BTU kerosene torpedo for years out side a heavy curtain area so the fan pulls the heat in from a high place and exhausts from a low place in the paint area. Never a contamination problem. I can maintain 80-85 degrees with the fan pulling out. I may have to get a heater that can burn diesel because kerosene is getting hard to get. The old Reddi Heater won't run on diesel.

Try looking at local gas stations. I have a BP in a neighboring town that has kerosene at the pump

I have the one below which has a label saying Kerosene or #1 grade fuel. Since Kerosene was getting hard to find and more expensive by the day it seemed. I did some research online and guys were advocating for diesel fuel with a small amount of gasoline added.

Being a bit afraid of the big bang scenario, I put half of the recommended amount of gasoline in and I gave it a try and it worked just fine. Since I don't use it very often, it has been running on the same mix for a couple of years now.

The kero around here is almost $ 7 a gal. But need it to run my booth in winter and heat the shop with oil .Same here no fish eye from the heater.
 
hmm, mine will light and burn with diesel, but when/if it cuts out it wont light again for a while. it will smoke too when it tries to relight.

Yes, I used to live in New York state and did dry wall finishing in some of those freezing homes. That's when I bought this heater and it has always worked great.
You're right about letting it run out of fuel though. Fogged up the place in seconds and made you gag.

Old drafty building. 20 foot high ceiling in the middle. Had to have something big. We were right next to an fuel/oil company so we had it sucking out of a 55 gallon barrel. If you ran it all the time you would go through a barrel in 2-3 days. Mainly would use it in the morning and when it was cold and the booth was sucking all the heat out of the building.
Oh and it felt pretty good if you had your back to it 10 feet or so away on a cold morning.

Same. When I was an electrician we used them in the houses we were wiring. Was really there for a handwarmer I guess when you couldn’t feel your hands anymore. Seeing as the houses had no windows, insulation, etc. Oh the good old days.
