My wife and i recently purchased a Jotul GF 600 DV II freestanding gas stove, which is scheduled for installation at the end of the month. We like the optional screen which, when in place with the doors open, makes the glass "disappear", but the dealer mentioned this cuts down somewhat on the amount of heat radiated through the front of the unit. My question is, where does this heat go? It seems like it has got to go somewhere; maybe through the top of the stove. Will I still get the same amount of heat from the unit with the screen in place as without? Thanks for your help....tonyg
