Fireplaces, Heating Stoves, Flues and Chimneys - Gas Fireplace Electrical Connection Questions

I recently bought my first house that has a Desa Natural Gas fireplace model CHDV32NR. It uses a Nova millivolt gas valve, model 0.820.625. Everything is maybe 2 to 3 years old. Now that it's getting colder I tried to turn it on for the first time the other day. The pilot starts just fine, but turning the Gas Control Valve to ON does nothing (pilot continues to work fine). I tested the voltage of the thermopile (at the TP to THTP terminals) and it was 535Mv. This is on the low side, but within manufacture's specs. After reading the manual, it references a wire between the TH and THTP terminal on the valve; there is no wire on my valve. Unfortuatly, the manual isn't specific on the electrical connections in any way. From my understanding, this is normally where a thermostat or switch would go and I can't figure out why it's not there. I decided to jumper it out (TH to THTP), and viola, the burner kicked on as expected. I asked the previous owner how she turned it on and she said she just used the Main Control Valve. At this point I'm just thinking the jumper was removed for whatever reason and not replaced/lost and I should just re-jumper it. This sounds correct to you guys, yeah?

Yup, that's where you connect a switch, thermostat or remote control. Anything over 400mv will work just fine, I've seen problems with overheating the thermopile with over 600mv and LP gas.

Usually you can find a place in the cabinet to drill a hole and install a toggle switch to turn the burner on and off conveniently.

There are also remote controls available if you are too lazy to haul yourself out of your chair to turn on a switch(!)

I just ended up ordering a remote - hooked it up according to the directions and it works exactly as it should. I've come to the conclusion it was just missing the jumper between TH and THTP for whatever reason, and that's what was causing my initial troubles.
