Kyle Kubs Posted June 27, 2007 Report Share Posted June 27, 2007 Anyone know if there is a required min. distance from a heating appliance direct vent termination to an A/C condenser? Can't find anything in the IMC. Obviously there is a common sense min. but since this is new construction I'm looking for something a little more firm.

Scottpat Posted June 27, 2007 Report Share Posted June 27, 2007 Any pictures? If it is directly over the discharge of the fan, this might cause a backdraft Other than that I can't see it being a problem. Link to comment Share on other sites More sharing options...
Kyle Kubs Posted June 28, 2007 Author Report Share Posted June 28, 2007 Pictures are on my other computer at the moment. But the discharge from a direct vent water heater is less then two feet away from the condenser. At the least, while the water heater is running it's putting out hot air right next to the condenser that is trying to cool refrigerant. Granted, it's probably nothing more than lost efficiency and overworking the A/C system. It was also clogged solid on one side, looked like lint you would find if a dryer discharge was too close but no dryer vent in sight. Link to comment Share on other sites More sharing options...
Terence McCann Posted June 28, 2007 Report Share Posted June 28, 2007 I wouldn't be worried about the extra heat but the acidity of flue gas might have an adverse effect on the fins. The vent would have to be discharging right on the unit though. Link to comment Share on other sites More sharing options...
