Need some opinions please... I've got a GOSM 3405BGW that runs hot. The lowest temp I'm able to achieve under any scenerio is around 275-285 degrees. I've read the instructions thoroughly and consulted w/ the manufacturer. The 1st CFM customer service rep said that the regulator was bad & they'd send another. They didn't, so I called back and got a guy who said: 1.) The 1st person I spoke w/ is "new" and is "wrong" 2.) "275 is the lowest temperature one can hope to achieve w/ this unit" SO... I'm considering adding another vent in the top of the unit to help bleed off some heat in hopes that I can get it to stabilize at around 225-250. Think it'll work?
