Any HVAC techs out there??? I have a Q?

[jbett98]

Was this house converted to natural gas after it was built?
The route they took for the vent sure looks like an after thought.

Great thanks, they did wrap the carpet and padding right up in the duct so I will cut the back.
I'm going to enclose it but just caulk the seams so if need be I can cut the caulk and get to it.

Thanks for all the info guys, this is why I love this community.

I'm not sure about gas vents, but I went through and replaced all the tape on my furnace ducts with mastic and fiberglass mesh tape (the kind used for drywall). I'm not sure if you can use that for gas vents, but it's my understanding that mastic basically lasts forever and seals better than the tape that dried out from the heat and was leaking.
