Propane heater burning eyes

Hi Eric

It sounds like the heater is getting the air in the room so warm that it's making your eyes and nose hurt. That can be from dryness, from heat, or from combustion products.
Depending on the partucular model, you can try to:

1. Turn the set temperature down.
2. Turn the turbo fan to a lower setting.
3. Turn the feed valve from your propane tank to a slower feed. At some point, you should be able to throttle the amount of fuel burning in a period of time to where the heat is more bearable.
4. If you're smelling fuel, or overt burning petroleum smells, turn the unit off. This is a sign that things aren't burning right.

Last, but probably most important. If you are running a unit like this inside, make sure you have windows open. Please take me seriously here - installed propane furnaces have heat exchangers to pull in fresh air, heat it, and pass that air into your house. A propane heater burning inside your house is burning your inside oxygen and, depending on the flame quality, dumping Carbon Dioxide or, worse, Carbon Monoxide, into your house. You can end up dead pretty quickly, especially from Carbon Monoxide poisoning, and you'll likely be feeling fine right up to the time you pass out. These types of heaters are meant more for outside use, so please, if you absolutely feel you must run it inside, keep windows open and have a fan running. You're playing with your health

Good Luck!

Could be escaping gas. Gas providers usually ensure the gas they supply smells bad so leaks are difficult to ignore. I have never experienced stinging eyes from the gas though.
Stinging eyes and possibly a dry and scratchy throat sound more like a heater that is burning inefficiently and producing excessive amounts of soot and carbon monoxide and probably other foul and potentially dangerous substances in addition.

All heaters produce such gases and should not be used without ventilation but when a heater is in a good state of repair and burning efficiently the emissions and the ventilation required are minimal.

From your description it would seem something about your heater is faulty and you should not be using it until it has been checked and declared fit to be used, when you should find it no longer stinks or makes your eyes sting.

One thought, if you have a dog about the place that has spent all summer marking his territory on your heater, it will stink, really stink, and make your eyes sting for a considerable time...

ur blower may not be producing enough air flow to constantly keep the air switch closed

Your eyes burn because the flame is burning too rich or too lean. Always start troubleshooting a fuel delivery problem by setting the pump pressure.

If the pressure is correct, check for a restricted fuel filter, a cracked end cover, air or vac leaks between the pump/nozzle and tank/nozzle.

DESA recommended annual replacement of the nozzle because they wear out and start producing a spray rather than a fog.

I would not use it any further, I cant say if anything is in the gas, I doubt it, However the propane at too low a pressure etc, can cause this, dont use it with eyes butrning ever!

Go to my tip at http://www.fixya.com/support/r4124129-yearly_maintenance_reddy_heaters for all your answers. Your air fuel mixture is off. You need a new air filter and need to set the bleed air. For that you need special tools which you can get at the information I give at my tip. Let me know if you need anymore help.

Thanks for using FixYa

Ours didn,t burn liquid propane too well, so ccheck your connections on your tank for vapor or liquid.

This heater should only be used in a very well ventilated area, the sore throat and burning eyes are from carbon monoxide.
Carbon monoxide is potentially fatal.  I cannot express how dangerous this is if used in a house or garage without the doors open
Please be careful and let me know if I can provide furthur assistance.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/jason_77a19afa8d604dee

Need to make sure you are supplying a minimum tank supply of 100lb cyclinder. If smaller,you are producing co due to low gas flow

These produce large amounts of carbon monoxide, so you essentially are poisoning yourself. Leave the garage door open part way when using it.
