This article applies to oil-burning equipment except internal combustion
engines, oil lamps and portable devices such as blowtorches, melting pots
and weed burners. No portable oil stoves are permitted or shall be used.
As used in this article, the following terms shall have the meanings
indicated:
Kerosene or any hydrocarbon oil conforming to Specifications for
Fuel Oils of the American Society of Testing and Materials, ASTM D396-48T,
and having a flash point not less than 100° F.
An oil burner of any type, together with its tank, piping, wiring, controls and related devices, and shall include all conversion oil burners, oil-fired units and heating and cooking appliances, but excluding those exempted by § 104-42.
A permit shall be required for the installation of any oil burner that
utilizes a fuel oil tank in excess of 25 gallons in a building or in excess
of 60 gallons outside of a building.
Oil-burning equipment shall be of approved type.
A.
The installation shall be made in accordance with the
instruction of the manufacturer.
B.
The installation shall be such as to provide reasonable
accessibility for cleaning heating surfaces, removing burners, replacing motors,
controls, air filters, draft regulators and other working parts and adjusting,
cleaning and lubricating parts requiring such attention.
C.
After installation of the oil-burning equipment, a complete
cycle of operation tests shall be conducted to make certain that the burner
is operating in a safe and acceptable manner and that all safety devices function
properly.
The grade of fuel oil used in a burner shall be that for which the burner
is approved and as stipulated by the manufacturer. Crankcase oil or any oil
containing gasoline shall not be used.
A.
An unenclosed, inside fuel oil supply tank shall have
a capacity of not more than 275 gallons. Not more than one two-hundred-seventy-five-gallon
tank or two tanks of aggregate capacity of 550 gallons or less shall be connected
to one oil-burning appliance, and the aggregate capacity of such tanks installed
in the lowest story, cellar or basement of a building shall not exceed 550
gallons unless separation is provided for each 275 gallons of tank capacity.
Such separation shall consist of unpierced masonry wall or partition extending
from the lowest floor to the ceiling above the tank or tanks and shall have
a fire-resistance rating of not less than two hours.
B.
Stoves which are designed for barometric feed shall not
be connected to separate oil supply tanks.
C.
Non-flue-connected stoves are prohibited.
D.
Supply or storage tanks located above the lowest story,
cellar or basement shall not exceed 60 gallons' capacity, and the total
capacity of tanks so located shall not exceed 60 gallons.
E.
Oil supply tanks shall not be located within five feet,
horizontally, of any fire or flame.
F.
Interior tanks exceeding 275 gallons' individual
capacity shall be installed in an enclosure constructed as follows: The walls
of the enclosure shall be constructed of solid masonry units or poured concrete
construction having a fire-resistance rating of not less than three hours.
Such enclosures shall be installed only on concrete or other fire-resistive
floors and shall be bonded to the floors. Enclosures shall have tops of reinforced
concrete at least five inches thick or equivalent fire-resistive construction,
except that where 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 liquid tight sills or
ramps. Provision shall be made for adequate ventilation of such enclosures
prior to entering for inspection or repairs on tanks.
A.
A fill pipe on a tank larger than 60 gallons shall terminate
outside of a building at least two feet from any building opening. Every fill
terminal shall be equipped with a tight metal cover.
B.
A return line from a burner or pump to a supply tank
shall enter the top of the tank.
C.
An auxiliary tank installed in the supply piping between
a burner and its main fuel supply tank shall be filled by pumping from storage
tanks.
D.
All piping, except the burner supply line from a tank
having a capacity not over 275 gallons and the cross-connection between two
such tanks having an aggregate capacity of 550 gallons or less, shall be connected
into the top of the supply tank.
E.
The burner supply connection to a tank or tanks having
a capacity of more than 275 gallons shall be connected to the top of the tank,
except that, in commercial and industrial installations for Nos. 5 and 6 oil,
the burner supply connection may be below the liquid level.
F.
Vent pipes shall terminate outside of buildings not less
than two feet, measured vertically or horizontally, from any window or other
building opening. Vent terminals shall terminate in a weatherproof vent cap
which shall have a minimum free open area equal to the cross-sectional area
of the vent pipe. The static head of the vent pipe when filled with oil shall
not exceed that pressure at which the tank was pressure tested.
G.
Pressurized tank feed shall not be used.
H.
All tanks in which a constant oil level is not maintained
by an automatic pump shall be equipped with an approved method of determining
the oil level.
A.
An oil pump not a part of an approved burner shall be
a positive displacement type which automatically shuts off the oil supply
when stopped.
B.
All piping shall be standard full-weight wrought iron,
steel or brass pipe or brass or copper tubing. Aluminum tubing shall not be
used between the fuel oil tank and the burner unit. Approved flexible metal
hose may be used to reduce the effect of jarring and vibration or where rigid
connections are impracticable and shall be installed only after approval.
C.
Piping used in the installation of oil burners and appliances
other than conversion-range oil burners shall be not smaller than three-eighths-inch
iron pipe size or three-eighths-inch outside diameter tubing. Copper or brass
tubing shall have thirty-five-hundredths-inch nominal and thirty-two-hundredths-inch
minimum wall thickness.
D.
Pipe shall be connected with standard fittings, and tubing
with fittings of approved type. If used, connectors shall be of approved type
and installed in accordance with their approval. Unions requiring gaskets
or packing, right and left couplings and sweat fittings employing solder having
a melting point of less than 1,000° F. shall not be used in oil lines.
Cast-iron fittings shall not be used. All threaded joints and connections
shall be made tight with suitable lubricant or pipe compound.
E.
Readily accessible manual shutoff valves shall be installed
at each point where required to avoid oil spillage during servicing. The valve
shall be installed to close against the supply.
F.
Where a shutoff is installed in the discharge line of
an oil pump not an integral part of a burner, a 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 supply tank or to bypass it around
the pump, unless the pump includes an internal bypass.
Oil burners shall be provided with some means for manually stopping
the flow of oil to the burner. Such device or devices shall be placed in a
convenient location at a safe distance from the burner.
