We interpret this provision to defer to the equipment manufacturer's installation instructions. $58.20. Remove the cover to access the drain. - ICC IMC 307.2.5 & IRC M1411.3.3 Drain Line Maintenance code for 2015, original source: http://www.iccsafe.org/, Devices or methods for providing condensate drain cleaning or de-clogging are discussed in this companion article: CONDENSATE DRAIN CLEAN & DE-CLOG, The following HVACR condensate disposal recommendations summary cites, paraphrases, & comments on the widely adopted 2006 ICC model building code section on condensate disposal, section 307 [7], For the two Types of Condensate: Fuel burning devices vs Evaporators & cooling coils. Where a product has multi speeds, a typical installation has been used for the below calculations. See ANSI/ASHRAE/IES Standard 90.1-2010 & 2012 IECC, "Insulation Requirements in Commercial Buildings for Mechanical and Service Hot-Water Piping", ASHRAE Standard 90.1-2010, Section 6.4.4.1 HVAC System Pipe Insulation, lists HVAC piping requirements and as an EXCEPTION, excludes from that requirement ", ICC, International Code Council, 500 New Jersey Avenue, NW It appears that this condensate drain only drops into that vertical standpipe an inch or two and if there is still a decent opening around it to let air into the standing drain line then you got an air gap between the end of the condensate drain and the P-trap below so it should be okay. Storage tanks shall be tested in accordance with the Section 1301.10.11. Fitted with 20mm pipe connection for running off condensate. Must be used where pipe ducts pass through unheated roof voids. required by the equipment or appliance manufacturer." Or should the air handler be seated on rubber be seated on rubber bushings? [P] 888-ICC-SAFE (888-422-7233) condensate pumps, and the detection and hazards of air conditioning system condensate leaks in buildings. My question is: Is it in violation of building or installation codes to not have a condensate drain line? "The information in this guide is a summary of requirements Material: grey PVCu. Sometimes we can’t (or don’t want to) vent through the roof line.In these rare cases plumbers use an Air Admittance Valve. Check it periodically and clean, if necessary." Clean the drain lines at the access point. Not suitable for use with flexible ducting. Must be used where pipe ducts pass through unheated roof voids. In a properly sized drain line, the plant being drained and the body of the steam trap are virtually at the same pressure and, because of this, condensate does not flash in this line. Watch out: in our OPINION and as we discuss in these articles, while a trap on a condensate drain line, usually provided quite close to the condensate collection pan itself, can reduce the chances of sewer gases backing up from a condensate drain that has been connected to the building DWV vent piping (not a procedure we recommend), a conventional P-trap in the condensate drain will not protect against all sewer gas backup possibilities. Air-conditioning condensate waste pipes shall connect indirectly to the drainage system through an airgap or airbreak to a properly trapped and vented receptors dry wells, leach pits, or the tailpiece of plumbing fixtures.
