used for an extended period of time during freezing conditions, shut down the system and completely drain the water heater.
If the water pipes should freeze, thaw the pipes with a hair dryer or other electric heating device. If this does not work, call a qualified
service technician.
Failure to provide freeze protection could result in substantial property damage due to burst pipes, personal injury, or death.
If the water heater is not to be used for an extended period of time during freezing conditions, consider shutting down the system and
draining it of water. Shut off the gas and cold water supply valves.

failure, substantial property damage, and/or severe personal injury or death due to electric shock, fire, or explosion. If repairs are
required, contact a qualified service technician.
