Several years ago, 8 or so, I bought a 27" DCS grill and converted it
from natural gas to propane. Just recently we moved and I now have to
convert back to propane. I've called Fisher & Paykel/DCS by Fisher &
Paykel, which I think is the DCS parts distributor, but they require a
model number. Unfortunately, I have a serial number for my unit, but
the model number appears to have rubbed off. Has anyone got any idea
how I can determine what model this 27" DCS grill might be. It's
really been a good grill, and I hate to give it up just because I
can't figure out the model.

Thanks in advance
