one other thing nobody has mentioned... a big part of the reason for
venting isnt in the summer, but in the winter. you want the air space in
the attic to be about the same temp as the outside air to keep the snow from
melting too quickly and re freezing as it hits the edge where the roof
overhangs the house. this is known as an ice dam. pumping heat into the
attic will cause them.

Recently I added a room to my house requiring that the gas dryer vent be
rerouted. The contractor routed it up into the attic. He was going to
run
it through the attic then outside the house but never finished it. He
said
it would be fine just up into the attic without being vented outside.

Are there any problems just leaving it venting inside the attic?


Thanks
