propane temperature contoller

[kenny chaos]

I'm building a smoker with all the bells and whistles and want to have an automatic temperature contoller, of some configuration, for the propane burner. Temps need to range from 40-300 degrees. Any ideas?
Thanks

I've never seen anything off the shelf, but an old oven thermostat might work. 40 degrees is hard to achieve without refrigeration. :coolsmile:

Not when ambient is 20.

You may need two thermostats, one for high temp and one for low. Not sure I've seen anything that would do the wide range that you'd like.

A thermostat/alcohol bulb gas valve out of a propane oven and one out of an old camper trailer would give you the high/low. Then you'd have to tee in the two gas valves into one burner. Just simply use which gas valve that you want for whatever range you seek.

Just be careful!

Okay, I just thought that was a typo or something.

I'm going to guess that you need something that modulates and doesn't snap on and off. It would be real easy to hook up a cheap thermostat to an electric gas valve, but not very steady.
