Hey had my house up and running for a bit now but I was waiting for a few fittings to finish my garage install. Now I got all the plumbing hooked up, I need to figure out the thermostat. In my house I just added a second thermostat and use it to switch the fan on. But the reznor heater needs to have the flame run for a bit before the fan kicks on so how do I get around that? I tried a jumper around the sensor and the fan won't shut off. Any ideas?

What sensor are you putting the jumper on?

[MNRVGuy]

Inside the back on the bottom there are three sensors on that has 2 black wires when I jump around that one the fan is on all the time. Another had green/yellow jump that seemed to do nothing. Run out of time the the one the two wires go to the gas valve.

So jumpering that sensor turns the fan on and it shuts off when you remove it? What voltage is it running at?

[MNRVGuy]

I did not check voltage. But there is a 24v transformer on the back. I put the jumper in withe power off to unit. I turn t-stat all the way down not calling for heat and turn power back on and the fan comes on and stays on until I cut power. Hard to work on I have to remove fan and cage for fan to get at sensors. Heats up space fast using gas and blowing thru the hx  but I sure would love to turn off the gas!

Does it have a wiring diagram on it?
If attach wires to the sensor then you can see if they make the fan go on and off when you tough them together. If they do then you can connect a thermostat directly to it is it is low voltage. (I would get one that does not need external power to be safe)

In my garage I use an electric base board heater thermostat. The tstat only has 2 wires coming from it and I just put in between one of the hot wires (120 volt) that run between the power supply and the blower motor. These tstats just break 1 leg in a 220 base board heater and it works great.
