Exterior Drain Pipe
You need to protect the tankless drain pan's drain pipe located outside your house. The freezing takes place at the point where the water exits the pipe. Ice will form at the ground level and rise to the bottom of the pipe, blocking the condensate flowing from the pan.
Heat tape is the only thing that works

Heat tape wrapped around the exterior drain pipe.
Even if your drain pipe is only a few inches long, this will work. Place the plug on a timer from 8pm to 11am to be on.
Insulate the drain pipe with regular pipe insulation.
In order for the heat tape to be used correctly, it must be insulated with regular pipe insulation. You can buy any big box store.
EXTREME weather warning...
Outside temperatures below 30 degrees
When the outside temperature is 30 degrees or below, you must stream the hot water so the tankless unit runs at its lowest level to prevent any components from freezing. Stop streaming when the outside temperatures reach 32 or above.
Also, the tankless unit has a built-in heater to protect the internal piping. However, it does not protect any other components attached to the tankless system as installed. Streaming water is mandatory, whether your electricity is on or off. If this is not abided by, the warranty is null and voided.
Away from home for an extended time during the winter months
Away from your home for an extended time during the winter months with the possibility of electrical power failure. You must follow the above steps. Drain the water from the tankless unit and remove the lower filter housing and cartridge.
Your warranty does not cover frozen tankless unit or filter housing. (See warranty)
