Ah. This installation is under the house in the crawlspace so he was going to put a pipe to vent out the wall and turn it maybe 6 feet up. A short new chimney. I do not know if this particular unit is designed to be ventless indoors. I was a little concerned that it might asphyxiate someone standing next to the house, but he said there is no danger. I gather they put the pipe up in the air anyway. The pipe does not have be heavy or insulated. The present chimney goes up to the roof. >I think it kicks in > > below 40 deg F. > > 40F is cold?
