Lighting and Shutdown
Extended Shutdown Periods
If the water heater will not be in use for an extended
period of time, the appliance's gas and water should
be turned off and the water heater drained to conserve
energy and prevent a buildup of dangerous hydrogen gas.
NOTE: Refer to Hydrogen Gas Caution, page 4.
49-6000245 Rev. 2
The water heater and pipes should also be drained if
they could be exposed to freezing temperatures. After
a long shutdown period, the water heater's operation
and controls should be checked by a qualified service
technician. Confirm that the water heater is completely
filled before placing it in operation.
NOTE: Refer to Water Tank, page 11.
