Anybody got one of these? It's the round stainless steel part that covers
the vent on the outside of the van.  Held on by three screws. thanks-Michael
What happened to mine you ask? We had a problem with the fridge going out
and being hard to relight. It would light, burn for maybe a minute, then
slowly die out(even with the safety button pressed) Found that if I took off
the cover and blew some air down the flue it would stay lit indefinately.
Unfortunately the last time around I guess the screws didn't get tightened
enough.
