Install a secondary pan at least 3″ wider than the appliance (1.5″ in each direction) and condensate overflow protection to ensure that an overflow won't result in MAJOR damage in accordance with IMC 307.2.3 When it comes to condensate in an attic CHECK EVERYTHING TWICE.
@ # @ The applicable Codes are the `12 IMC & IPC. I am looking for Code Sections regarding condensate drain lines. QUESTION: Can condensate drain lines connect directly to the sanitary sewer system, or must there be an Air Gap or Air Break at the point of termination. Thanks ! @ # @

IMC 307.2.3 states that all HVAC equipment that produces condensate must have either a secondary drain line or a condensate overflow switch, a secondary drain pan with a secondary drain line or condensate switch or some combination of these installations should be used to prevent overflow if the primary drain line blocks. IMC 307.2.3.1 Water-level monitoring devices. On downflow units and all other coils that do not have a secondary drain or provisions to install a secondary or auxiliary drain pan, a water-level monitoring device shall be installed inside the primary drain pan. All-Access switches are IMC code 307.2.3.4 compliant AA1 and AA1-FS are IMC code 307.2.5 compliant inline cleanout devices AA1 features Schrader valve pressure cleaning AA1 insulation protects your cleanout and switch device from sweating in unconditioned spaces
