Re: REDDY HEATER R165AT
In order for the unit to fire up, the little air compressor on the rear of the fan needs to provide 3.6 lbs of air. if your nozzle is clogged it won't fire. for more troubleshooting tips try www dot desatech dot com. this is a site for reddy heat products and parts.

I assume the heater ran fine last season. If so, assume it will run fine this season. Simply remove the top cover, check the combustion chamber area for signs of visitors such as mice, wasps, dirt dobbers, etc. Remove debris.
We always drain the old fuel & start fresh.
Replace the top cover and fire it up. If it runs fine then leave it alone. If it won't continue to run troubleshoot and find the problem.

Troubleshoot a hot surface ignitor type heater http://www.reddyparts.com/HSI_tips.htm
This doesn't help. There at least 4 60k Reddy Heaters models -some are spark plug heaters, some have the new Hot Surface Ignitor technology. All heaters have specific model. Without you knowing the model I can't help, sorry.
the ignitor is faulty, mine also did that and I noticed one night that it was shorting out right from the ignition box. I put in a new ignitor and flame sensor and it's fine now. All ignitors are basically the same you just have to do some creative wireing. reddyparts.com still has most parts for your heater.
If the heater runs fine for the 15 or so minutes without smoke/odor- do this
check for water droplets on bottom of tank
check for restricted fuel filter
test safety control (reset)
You don't state whether this is a spark plug heater *or* Hot Surface Ignitor type. I made the assumption you were inquirung about a Spark Plug Heater. Disregard the list if the heater is an HSI type---- troubleshooting is different.
turn off power to furnace and open the front panel and see if you can see burners and gas valve and Hot surface ignitor. If you can. turn furnace on and watch to see if the ignitor glows. Let me know what you find. If it doesn't glow you probably have a faulty Hot surface ignitor. If I had make and model number I should be able to find the part
what kind of ignition is it? spark or hot surface igniter? the photocell just detects the flame. it causes the controller to go into lockout if it doesn't detect a flame. a hot surface igniter uses 120 volts to operate, again off the controller.
propane heater uses a hot surface ignitor. this operates off 120 volts and glows red/orange when actuated. it stays lit throughout the heater on operation. on the backplate of the combustion chamber is a high limit with two wires coming off it. these two wires connect to the spade connectors on the flame detector cappillary. Once you establish a fire, the flame detector generates a 750 millivolt signal which is applied to the pilot/main valve assembly. My diagram will show this.
