condensate line.

Turning the Unit Back On

After the water heater has been out of use for a long time make sure that you fill
the condensate trap with water.
This is to prevent dangerous exhaust gases from entering the building.
Failure to fill the condensate trap could result in severe personal injury or death.
(By performing step 4 as described above, the condensate trap will automatically
fill itself with water.)
