Gas Drier Venting

ARTSBEST

What is acceptable plumbing codes-wise regarding venting my gas drier to my crawl space instead of to the outdoors? Is a special box to filter things out necessary?

There is actually an indoor dryer vent kit but I would never use one nor would I vent it in the crawl space. The lint is a fire hazard and the moisture can cause all types of problem like mold, mildew and wood rot. Get an electric dryer if you don't want a vent.

I forgot about the code question, every place I know of it's against code.

There is no way to filter out carbon monoxide. Bad stuff...Seems to me that electric dyers also utilize a vent. For lint, heat, and moisture. You should vent it to outside. The lint alone makes for an extremely dangerous situation. I have been under houses where I refused to fire up my torch.

Worried what could ignite! You need to get that stuff to the outside

The electric dryers do have a vent but for electric you can use the indoor vent that has a lint trap.

You still have the problem of dumping all that moisture in an unheated crawlspace...disaster waiting to happen.

Problems aside, it is technically a code violation.

THANKS everyone was for the most imformative/inclusive responses. I second guessed the plumber when he told me to vent into the crawl space. It didn't sound correct to me either.
