!NOTE

Upon completing installation, make sure that the Oxymitter 4000 is turned on and operating prior to firing up the combustion process. Damage can result from having a cold Oxymitter 4000 exposed to the process gases.

During outages, and if possible, leave all Oxymitter 4000 units running to prevent condensation and premature aging from thermal cycling.

If the ducts will be washed down during outage, MAKE SURE to power down the Oxymitter 4000 units and remove them from the wash area.
