* The shapes of the cleanout plugs are as pictured on the right.
* The cleanout plugs may not be clearly visible as they are partially
hidden behind the pipe insulation.
* Water may not drain out fully even though the cleanout plugs are
loosened, depending on the pipe arrangement. In this case, fully
remove the cleanout plugs. (Make sure not to mislay them.)
When Unused for an Extended Period-2
Position of the cleanout plugs
3 positions
If the water heater will not be used for a long period of time,
drain the water.
Turning the Unit Back On
1. Check that all drain plugs are inserted.
2. Check that all hot water fixtures are closed.
3. Follow the procedure on P11 “Initial operation”, steps 1 through 4.
4. Make sure that the area around the appliance is well ventilated; open a window or a door if necessary.
Then, operate the unit and verify that condensate is coming out of the drain pipe.
(During normal use of the water heater, condensate will begin to discharge from the drain pipe within 30
minutes of use. However, depending on the season and/or installation site conditions, it may take longer.)
* If water does not appear at the end of the drain line, a qualified service technician must clean the
condensate line.
After the water heater has been out of use for a long time or after replacing the
drain trap with a new unit, make sure that you fill the drain trap unit with water.
This is to prevent dangerous exhaust gases from entering the building.
Failure to fill the drain trap unit could result in severe personal injury or death.
(By performing step 4 as described above, the drain trap unit will automatically
fill itself with water.)
Be sure to do.
