Mike Lamb Posted July 14, 2014 Author Report Share Posted July 14, 2014 I am not sure I have ever seen vents installed vertically. Anyhow, the manufacturer's instructions for this model furnace says the vents should be installed as shown in their diagram which is a horizontal installation. I was wondering if this is anything to get worked up about. Quote Link to comment Share on other sites More sharing options...
Mike Lamb Posted July 14, 2014 Author Report Share Posted July 14, 2014 I just talked to a Ducane tech and he says it's not a problem. Quote Link to comment Share on other sites More sharing options...
Tom Raymond Posted July 14, 2014 Report Share Posted July 14, 2014 Those look horizontal to me, or are you referring to the elbow? Quote Link to comment Share on other sites More sharing options...
kurt Posted July 14, 2014 Report Share Posted July 14, 2014 Due to People's Gas restrictions about venting into any gangway <10', just about everyone is now running them up through the roof. There's nothing wrong with vertical installations according to the guys I work with. I looked it up a few years ago, and found nothing that says vertical is a problem.

Mike Lamb Posted July 14, 2014 Author Report Share Posted July 14, 2014 Those look horizontal to me, or are you referring to the elbow? No. I'm talking about a vertical wall install with the vents on top of each other rather than side by side. Quote Link to comment Share on other sites More sharing options...

kurt Posted July 15, 2014 Report Share Posted July 15, 2014 Makes no difference. Why would it? Quote Link to comment Share on other sites More sharing options...
Mike Lamb Posted July 15, 2014 Author Report Share Posted July 15, 2014 I was wondering if the instructions and illustrations which always shows the vents side by side had a good reason for this. I would think you would not want the exhaust located directly below the intake, for instance. I know it makes practical sense to vent side by side since most often the furnace is vented from the basement just above the foundation in wall installs.

David Meiland Posted July 15, 2014 Report Share Posted July 15, 2014 If you did everything perfectly wrong, with the exhaust above the intake, condensate could drip into the intake. You would have to be exceedingly clever to screw it up that badly, but it could be done. In any case, they figure you're going to run two pipes side by side on the ceiling, or in a joist bay and out the rim... horizontal. Quote Link to comment Share on other sites More sharing options...
ejager Posted July 20, 2014 Report Share Posted July 20, 2014 I'll right, I'll bite. Why are there three pipes? They tried a few vertical installations in my area but it they always seemed to have problems. Could be the long runs from the basement up through two floors and then an attic. Bigger vent piping didn't overcome the problems. In the extreme cases, the 'open concept' plans presented by architects never included a chimney chase and so the HVAC installers always had multiple jogs and horizontal runs as well.
