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.
