Hot Dawg question.

[Beegs]

I have been doing some reading on a heating unit for my garage. I am fairly certain I will be going with a propane fired Hot Dawg by Modine. My question is: what concerns do I have with the flame if I am doing some spray painting?

It has electronic ignition so no pilot light to worry about. I asked the rep. if they offered a sealed combustion type unit. He said Modine offers a Hot Dawg unit which has a cold air intake setup. It is not a completely sealed combustion unit. A couple people I have talked to say I am making a big deal out of this for no reason. They say to get the regular Hot Dawg and call it a day.

What do you guys think? TIA

What goes boom in the paint booth????

I just make sure the thing wont come on when spraying and that is it. I was afraid I would forget one time and go boom, 6 years and not forgotten yet. It was something I was concerned with also.

I guess my question wasn't specific enough. I know light fumes are explosive, I was hoping someone has had some experience with the "semi" sealed modine unit.

By cold air intake, he means just that. You put a hole in the outside wall and run a 4 inch duct into a hole in the side of the heater by the bunner area. It is more a conservation thing than a safty thing. The idea it that you are not useing heated air to supply the burners and then sending it up the the chimmeny. Some times they put something like a door weather seal on the burner acess door, but I have seen carful guys seal it with duct tape so no air from the room gets into the burner area.
If you have an outlet or light that only use when you paint, like an exhaust fan, you can get a electriction to set up a switch that turns off power to the heater whenever you turn on the exhaust fan. That would keep it from cycling on when you were painting.

That is a good idea, having the power turned off to it automatically. I'll have to give that a little thought to see how I can incorporate it.

Definitely a great idea.
