National Board of Fire Underwriters specifically for use in house
heating furnaces and boilers.
(b)
Oil burners for which a competent attendant will not be constantly
on duty in the room where the burner is located, while the burner

Oil burners for which a competent attendant will be constantly on
duty in the room where the burner is located, while the burner is
in operation, are not required to be equipped with automatic means
for preventing abnormal discharge of oil at the burner. When automatic
features are installed in connection with oil burners of this type,
such automatic devices shall be specifically approved for use with
the burner to which they are attached. Note: Oil burners of this type

oil, free from acid, grit and fibrous or other foreign matter likely
to clog or injure the burners or valves. The flash point shall be
determined by the Pensky-Martens Closed Tester, in accordance with
the method of test adopted by the American Society for Testing Materials
(ASTM) Designation D93-22), except that the Tag Closed Tester (ASTM
Designation D56-21) shall be authoritative in case of dispute concerning
oils having a flash point in the vicinity of 135° F.
(b)
The grade of fuel oil used with any burner shall be one approved
by the list of inspected oil burners issued by Underwriters'

a manually operated, approved three-way valve in such a way that only
one tank can discharge its contents at a time.
(c)
Where oil is supplied to the burner by gravity and a constant level
device is not incorporated in the burner assembly or in an auxiliary
tank used in connection with an automatic pump, an approved constant
level device shall be installed in the oil feed line at the gravity
tank or as close thereto as practicable, to insure uniform delivery
of oil to the burner. The vent opening of such constant level device
shall be connected by piping or tubing to the gravity tank vent pipe.

floors and shall be bonded to the floor. Enclosures shall have tops
of reinforced concrete at least five inches thick or equivalent fire-resistive
construction, except when the floor or roof construction above the
enclosure is concrete or other fire-resistive construction, the walls
may be extended to and bonded to the underside of the construction
above in lieu of the provision of a separate top. Any openings to
such enclosures shall be provided with fire doors or other approved
closures and six-inch noncombustible liquidtight sills or ramps. Provision

except that, where this is impractical, the inspector may permit it
to terminate not less than 25 feet from any building, provided that
the hose from the filling truck shall not extend across the sidewalk.
Fill terminals shall be closed tight, when not in use, by a metal
cover designed to prevent tampering. In tanks containing heaters the
tank end of the fill pipe should be sealed by a trap or should be
extended to a point below the lower end of the suction pipe.
(b)
Auxiliary tanks shall be filled by pumping from storage tanks.
(c)
Cross connections permitting gravity flow from one tank to another
shall be prohibited. This, however, shall not be construed as prohibiting
the filling of an outside service tank by gravity, provided that filling
is through an open connection located within a dike surrounding the
service tank, and provided further that such dike shall have a capacity
equal to 1 1/2 times the capacity of the tank being filled.
(d)
Auxiliary tanks other than vacuum tanks shall be equipped with an
overflow pipe draining to the storage tank, at least one size larger
than the supply pipe.

manner. Union fittings shall be of an approved type. Unions requiring
gaskets or packing and right and left couplings shall not be used
in oil lines.

[Ord. No. 27A,
§ XX, 4-26-1935]
(a)
Readily accessible shutoff valves of approved type shall be installed
in oil supply lines near each burner and close to the supply tanks.
Shutoff valves of approved type shall be installed on each side of
oil strainers which are not a part of the oil burner unit, and on
the discharge and suction side of oil pumps which pump directly to
the burner but which are not a part of the burner unit.
(b)
Where a shutoff valve is installed in the discharge line of an oil
pump, an approved pressure relief valve shall be connected into the
discharge line between the pump and the shutoff valve and arranged
to return surplus oil to the storage tank or to bypass it around the
pump.
(c)
Control valves shall be of approved type provided with stuffing box
of liberal size, containing a removable cupped gland designed to compress
a packing against the valve stem and arranged so as to facilitate
removal. The valve shall be designed to close against the supply and
to prevent withdrawal of stem by continued operation of the handwheel.
Packing affected by the oil or heat shall not be used.
(d)
An automatic shutoff valve controlled by a fusible link designed
to fuse at an approved temperature shall be installed at a location
immediately adjacent to the burner.
[Ord. No. 27A,

shall be tested hydrostatically, or with equivalent air pressure,
at a pressure not less than 1 1/2 times the maximum working pressure
but not less than 10 pounds per square inch at the highest point of
the system. Tests should continue for at least 30 minutes without
a noticeable drop in pressure. The test shall be conducted in the
presence of an authorized representative of the Eastchester Fire Department
and at no expense to the Village.
[Ord. No. 27A,
§ XXIII, 4-26-1935]
(a)
Oil-burning equipment shall be provided with some means for manually
stopping the flow of oil to the burner, from a conveniently located
point at a safe distance from the burner. With electrically driven
equipment this may be accomplished by an approved safety switch in
the motor supply circuit, placed near the entrance to the room where
the burner is located. A quick-closing valve in the oil supply line,
preferably located outside the building, may also be used.
(b)
Automatically operated oil burners used in connection with hot-water,
steam or warm-air heating systems shall be equipped with approved
automatic devices to shut down the burner in the event of undue pressure
in a steam boiler or overheating within a hot-water boiler or warm
air furnace.

Oil burners used in connection with steam heating systems shall
be equipped with approved automatic devices for shutting down the
burner in the event of low water in the boiler. The device shall require
manual resetting or it shall prevent operation until the safe water
level is resumed.

mechanics experienced in making such installations.
(b)
Where oil burners are installed in furnaces originally designed for
solid fuel, the ash door of the furnace shall be removed or bottom
ventilation otherwise provided to prevent the accumulation of vapors
in the ash pit, unless the burner is of a type which mechanically
purges the ash pit.
(c)
Boilers and furnaces in which oil burners are installed shall be
connected to flues having sufficient draft at all times to assure
safe operation of the burner. Smoke pipe dampers, if any, shall be
such that they cannot close off more than 80% of the internal cross
section area of the smoke pipe.
(d)
Rooms in which oil burners are located shall be provided with adequate
ventilation to assure continuous complete combustion of the oil.
