• Provided with adequate space
(clearances) for periodic servicing.
(There must be a minimum of 24
inches of front clearance.)
• Installed with a minimum clear-
ance from combus ble surfaces as
stated on the ra ng plate.
• Installed on a fl oor that can sup-
port the weight of a water heater
full of water.
NOTICE: The state of California requires
bracing, anchoring, or strapping the
water heater to avoid its moving during
an earthquake. Contact local utilities
for code requirements in your area,
visit http://www.dsa.dgs.ca.gov, or call
1-916-445-8100 and request instruc-
tions. Other locations may have similar
requirements. Check with your local and
state authorities. See also Securing the
Water Heater (page 15).
