repositioning the regulator under a gas cooktop

I am trying to retrofit an older (well, not that old, I would say less than 10 years old) gas cooktop in place of an electric.
With the guidance of my gas fitters who ran the line into the house, I have successfully installed the series of elbows and nipples needed to make the connection and have tested the unit away from the counter top (it works well.)
The problem is, the regulator is currently installed in a clumsy position. It sticks straight down about 6 inches and in place it would block an exisiting drawer.
I think I see enough space that if I could remove the regulator and install an 90deg elbow and replace the regulator on the horizontal, I wouldn't have to lose the drawer.
Can anyone tell me if I should be able to remove and reorient the regulator? I gave it a few tugs with a pipe wrench but stopped when it became apparent that the threaded connection was stiff and wasn't going to disconnect easily. I don't want to force it if it was factory installed that way and shouldn't be tampered with.
If one can normally remove and reorient a regulator (it appears to be attached to a threaded pipe leading into the box), how should I best I loosen it? Would a shot with a blowtorch be safe to loosen the threaded connection?
thanks Peter
(hmmm, I have a photo of all this but I can't figure out if and how I can attach a photo to this post. Let me know if you need to see it and I can e-mail it to you.)

Should be fine to relocate it. Use 2 wrenches to loosen. Apply the wrenches so that the forces don't go *through* the regulator casting as it may distort. Never use heat on such a device as there are sensitive rubber parts inside.

[from buffalo ny] check for spiderwebs blocking openings if this unit has been in storage. electronic spark ignition is cheaper on fuel than pilot lights.

got it sorted. thank you all. in the end I took the metal casing off the unit which revealed a stainless steel tube ending in that threaded bit connecting to the regulator. Having eliminated the unknown I felt comfortable holding that with a wrench (plus the fact that I could now access it) and applying enough force to remove the regulator. I will hook it all back up this weekend. Thanks Peter
