Protection From Damage
1. Appliances 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 appliances installed within a garage are enclosed
in a separate, approved compartment having access only from
outside of the garage, such appliances may be installed at floor level
provided the required combustion air is also taken from the exterior
of the garage. Fuel burning appliances having sealed combustion
chambers need not be elevated.
3. All appliances 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, appliances 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 appliance 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 appliance is located in an attic, attic-ceiling assembly,
floor-ceiling assembly, or floor-subfloor assembly where damage
may result from a leaking appliance, a watertight pan of corrosion
resistant materials shall be installed beneath the appliance with
a minimum three-quarter (3/4) inch (20 mm) diameter drain to an
approved location.
