My question is: Is it in violation of building or installation codes to not have a condensate drain line? And to clarify that, an indirect waste pipe is something upstream of a trap rather than downstream, and this includes the main venting stack as well. Condensate drain lines shall be configured to permit the clearing of blockages and performance of maintenance without requiring the drain line to be cut. Where the drain pipes from more than one unit are manifolded together for vibration combined with condensation (and perhaps actual condensate) between the brick surface and the metal housing of the air handler invites corrosion and over a longer term, damage to the unitA vibration isolating pad such as the Wagner MP-6E EVA Anti-Vibration Pad 6x6 Inch Square by 7/8 Inch Thick pad shown below is a better practice.

Solutions often proposed are for a trap of sufficient depth that water in the trap will not evaporate sufficiently to lose the trap seal during periods when no condensate is being produced. Code requires that the condensate be connected to the building drain though an air gap connection and NOT physical to the drain. To get the data we need to design systems that mitigate those issues, we need to do a blower door test. Opening/closing doors and windows can also worsen the issues that stem from infiltration due to upsetting the balance of pressures in the home. Since there is a lot of room for inaccuracy in extreme climates (especially those with high latent loads), many HVAC systems are oversized and underperform.

GerardThe manufacturer of your air handler is the final authority on this installation detail but in my OPINION while it's common to see an air handler set into a drain pan on wood and sometimes other materials, a rubber anti-vibration pad would be a better practice for two reasons: @John W., When doing load calculations (Manual J), we need to know how much of the heat load, especially the latent heat load, comes from leakage in the building envelope and the ducts. It says that it must be disposed of into an approved location and that it shouldn't be dumped on walkways, streets, or alleys as to cause a nuisance.. I want to know if it is ok to run 6', sloped of course, out from the unit before putting in the trap.
