Gas furnace venting?

Otis Member Posts: 1
I am in the process of buiding a new home and was wondering if it would be safe to run intake and exhaust vent lines under a unexcavated garage.  Is it against code?  Will the condensate freeze in the exhaust pipe?

Thanks <strong>Brad</strong>

    It is not a good idea

    especially if you have problems and need to get atthe piping. If you are building you have a lot of flexibility now as to location so make it as short and easily accesible as possible.
