Chad with ECO systems came with me to see what the fire dept and enbridge shut down.
623-2 received a call from 623-2 unit at 2 am on Fri-Sat 2AM. Fire dept went to 623-2 and shut the gas off. 623-4 was shut off as well. Carbon Dioxide
The gas company Enbridge shut off gas.
In the video also notice venting pipes we talked about a while back. The venting is next to the evaporator coolers. When water heater is on, and the coolers are running at the same time, the carbon Dioxide is pulled from the stack into the cooler system
