To Turn Off Gas To Appliance - Bosch GWH-635-ES-N Manual

NOTE: on a first time initial
i
installation, existence of air in the
gas supply line will cause some
ignition delay when the hot water
is turned on and result in an error
(EA) on the display screen. This is
normal. You must turn off the
flow of hot water, reset the unit
(Fig. 28, pos. 2), wait for (EA) to
disappear, and then re-open the
hot water tap again. Repeat these
steps if the error (EA) repeats
itself until all air has been bled
from the gas line.
When the heater is in operation you will hear its power
vent fan and burner operating. Upon turning off the hot
water flow the power vent fan will continue to operate
for up to 60 seconds to exhaust all flue gases. The
power vents fan speed is variable depending on the rate
of hot water used and the burner output.

TO TURN OFF GAS TO APPLIANCE

B Turn off the manual gas shut off on the supply line to
the heater and set the ON/OFF switch to the OFF (0)
position. Note: a manual gas shut off valve is not
supplied with the heater.
