4. VACATION AND LONG TIME SHUTDOWN —
If the water heater is installed where it could freeze (summer cabin, lake
home, etc.) you must drain all water from it and the piping. If the tank is full
of water and it freezes, the tank will break. Freeze damage is not covered
by the warranty!
DRAINING THE WATER HEATER —
!
CAUTION
Always shut off power to water heater before draining water.
In order to drain water heater, turn off the power supply, then turn off cold
water supply. Next, it is necessary to open a hot water faucet or lift the han-
dle on the relief valve to admit air to the tank, and KEEP OPEN. Attach a
garden hose to the drain valve on the water heater, and open the valve.
Direct the stream of water to a drain where it will do no damage. (See Fig-
ure 19).
