OPERATING INSTRUCTIONS
WARNING
If the water heater has been damaged or exposed to flood-
ing, fire, or sooting do not operate the heater until all cor-
rective steps have been taken by a qualified serviceman.
FILLING
Before proceeding with operation of the water heater make
sure that the system is filled with water.
-
Turn the water flow selector handle clockwise
( )
against stop.
-
Open all hot water faucets connected to the W125K…to
allow trapped air to escape from heater and piping.
-
Close all faucets, once water flows freely and all air
has escaped from system.

SERVICE HINT
The screen (strainer) in the water valve, located in inlet of
the water valve, may require occasional cleaning due the
foreign material in the water supply. This will restrict the
flow of water and may affect heater operation and prolong
filling time. To inspect the screen, close the cold water sup-
ply valve ahead of the heater, disconnected cold water line
from inlet of water valve and remove screen from inlet. Clean
if required, replace screen in inlet to water valve, recon-
nected and open cold water supply valve.
