Protection From Damage
1. Water heaters generating a glow, spark or flame capable of
igniting flammable vapors may be installed in a garage, provided
the pilots, burners or heating elements and switches are at least
eighteen (18) inches (457 mm) above the floor level.
2. Where such water heaters installed within a garage are enclosed
in a separate, approved compartment having access only from
outside of the garage, such water heaters may be installed at floor
level provided the required combustion air is also taken from the
exterior of the garage. Fuel burning water heaters having sealed
combustion chambers need not be elevated.
3. All water heaters installed in areas where they may be subjected
to mechanical damage shall be suitably guarded against such
damage by being installed behind adequate barriers or by being
elevated or located out of the normal path of a vehicle using any
such garage.
4. In seismic zones 3 and 4, water heaters shall be anchored or
strapped to resist horizontal displacement due to earthquake
motion. Strapping shall be at points within the upper one-third
(1/3) and lower one-third (1/3) of its vertical dimensions. At the
lower point, a minimum distance of four (4) inches (102 mm) shall
be maintained above the controls with the strapping.
5. An water heater supported from the ground shall rest on level
concrete or other approved base extending not less than three (3)
inches (76 mm) above the adjoining ground level.
6. When an water heater is located in an attic, attic-ceiling
assembly, floor-ceiling assembly, or floor-subfloor assembly where
damage may result from a leaking water heater, a watertight pan
of corrosion resistant materials shall be installed beneath the
water heater with a minimum three-quarter (3/4) inch (20 mm)
diameter drain to an approved location.
