Had a Noritz CB199 Combi installed the contractor dumped the condensate drain under my house didn't like it nor is it up to code I installed a pump to drain and need to connect the fail shut off switch to combi did not find wire connection on unit so I contacted the manufacturer support they informed me that no wire connection was installed on unit what is the best way to connect fail switch on condensate pump to my system to shut unit down any help would be greatly appreciated

Your boiler most likely has an air pressure switch on it's internal condensate trap. Test it with a multi-meter to determine it's N/O or N/C state with the boiler running then connect it in series with your condensate pump's alarm relay common and N/O or N/C contacts.0

Why not tie into a thermostat with an alarm terminal (L)? At least the Homeowner will know there is an issue.0
