Alternative use for a down draft exhaust vent duct
Hi everyone,
I had a client ask me the other day if he could use an existing downdraft vent duct that runs through a concrete slab on grade to route a propane gas line in order to switch from electric cook top to a gas cook top in an island. I was under the impression that he wanted to use it as a pipe chase in stead of a ventilation duct. I later found out that he wanted to use the duct for both uses. I told him that it was unacceptable according to the current municiple code, which is 06 IRC. Was I correct?
Thanks for any feedback.

Re: Alternative use for a down draft exhaust vent duct
As a note of clarification, a gas line under a slab for a habitation is required to be in a chase pipe that is vented to allow the gas from a leak to dissipate away from the structure. There by not building up a gas pocket under the structure. You were right to tell the client that the use he had in mind was unacceptable.
