Hi blow heater out with air line flame sensor could be dirty check out pressure switch jump this out see if it lights

SOURCE: I have a dayton 30,000 btu heater ,,it will run

If you are pressing a small round switch with a tiny button in the center...means a bad heat exchanger. The heat from the exchangeris going where it is not supposed to and tripping a roll out switch. Have the exchanger checked for cracks or holes.....check vent pipe to make sure not plugged

Sounds like you have a bad gas hold on valve. I have a tip at http://www.fixya.com/support/r4258201-fix_gas_reddy_heaters_will_not_continue which explains the problem, how to fix it and where to get the parts. Let me know if you need more help.

Thanks for using FixYa and for the generous rating.

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,

achowe - Several things can cause what you have described.

Restricted air flow. Check the heater's inlet & for any obstructions.
Damage Fan - check the fan for any obvious damage.
Excessive dust or debris inside the heater or in the surrounding area.

To help you more, I am including a link to the Owners Manual for your heater. You can download and print it for future reference. If you find you need to order parts, they can be found online at Master Distributors. They stock all the parts for DESA/Reddy Heaters.
