These diagrams all imply, as well as I can tell, that the waste heat is
contained into a vent that will exit the roof.The actual burner heat and
vent is not shown here.In the vanagon, this waste heat is all contained
until it exits the grill behind the stove-and then goes into the pasenger
compartment.All I did was to keep as much burner heat as possiable in the
vent pipe where it belongs so it can exit the van completely. I think the
heat from the fins is will stay in the interior unless it is seperately
vented somehow. I did this by removing the fibgerglass insulation on the
van wall.I hope someof it will conduct out.
