I'm installing propane in my shed. Eventually I will have two appliances, a heater and a two burner stove. Currently I'm working on the heater. I installed the 1/2" copper supply line, fittings, shutoff valves, and finally the heater. The heater didn't work. I can't smell any propane at the heater. I moved the heater to the outside 30# propane tank. I connected a two stage regulator to the tank to a 1/2" steel corrugated line to a brass tee to shutoff valve to a 3/8" steel supply line to the heater.
I hear pressurization when I turn on the tank's valve. I hear pressurization when I turn on the shutoff valve. I don't smell any propane at the heater. I smell propane coming from the tank. I smell propane coming from the shutoff valve.
I tried the heater each time in a vertical position as if the heater were mounted.
I followed the heater's instructions to depress the setting knob in the pilot light/ignition position for 30 seconds. I tried moving the knob to the high setting and did not smell propane.
I removed the tee and one of the shutoff valves from the test configuration, using only a single shutoff valve. I smell propane when the 3/8" line is not connected to the heater. I smell no propane from the heater when the 3/8" line is connected to the heater.
The tank and supply lines seem to be fine. The heater doesn't seem to be working. The first heater I bought is a Pro-Com MD100HBA. When it didn't work I returned it and bought a similar looking heater with a name badge of Williams. Both heaters are rated at 10,000 BTUs.
What's going on and how do I fix this?
