(AGA). Gas-burning equipment shall include the gas burners, ignition equipment, gas-control
valve, gas piping, gas-pressure regulating valve, when applicable, and accessories necessary
for a fully automatic system that is listed in IAS Directory. Gas-fired units equipped with
programming controls shall be furnished both with high and with low gas supply pressure
switches in the fuel supply piping. Ignition systems shall be of the direct spark, hot surface, or
interrupted intermittent type with automatic electric ignition. The pilots shall be of the
electrically-ignited proven type. Continuous pilots will not be permitted. Burner shall be
designed in accordance with NFPA 54 and located so that parts are protected against
overheating. Provisions shall be made in the burner housing for inspection of the pilot flame.
Vent piping shall be in accordance with UL 441, [Type B] [Type BW]. Vent shall conform to
NFPA 211 and NFPA 54. Plastic materials polyetherimide (PEI) and polyethersulfone (PES)
are forbidden to be used for vent piping of combustion gases. [Direct venting shall be used for
high efficiency, condensing type furnaces. Both the air intake and exhaust vents shall be sized
and located as recommended by the furnace manufacturer. A separate combustion air intake
vent and exhaust shall be provided for each furnace. The combustion air intake piping shall be
constructed of Schedule 40 PVC in accordance with ASTM D 1784. The exhaust vent piping
shall be constructed of Schedule 40 CPVC or stainless steel in accordance with UL 1738 and
the furnace manufacturer's recommendations.]
10.7.4.2 Oil-fired furnace. The equipment shall include the oil burner motor, ignition
equipment safety devices, and accessories necessary for a full automatic system that conforms
to UL 296. Oil-fired units equipped with programming controls shall be furnished with low oil-
pressure switches in the fuel supply piping. Oil-fired units not equipped with programming
controls shall be equipped with a delayed opening or shutoff valve. The valve shall
automatically delay delivery of oil to the burner until such time as the combustion air fan and,
when applicable, the induced draft fan are operated at rated speed. Ignition systems shall be of
the [direct-electrical spark type] [direct-electric spark type or interrupted type] in accordance with
UL 296. Vent piping shall be in accordance with UL 641, Type L. Vent shall conform to NFPA
211. Plastic materials polyetherimide (PEI) and polyethersulfone (PES) are forbidden to be
used for vent piping of combustion gases.

CENTRAL HEATING EQUIPMENT. Minimum equipment efficiencies shall be in
accordance with DOE Buying Energy Efficient Products Recommendations ( refer to
10-8.1
Hot water boilers, gas fired. Boilers shall be gas fired and shall be designed,
constructed and equipped in accordance with the ASME Boiler Pressure Vessel Code, Section
type. The boiler capacity shall be based on the ratings shown in HYI-01 or as certified by the
American Boiler Manufacturers Association, or American Gas Association. Boiler shall be
designed to burn gas. Each boiler shall comply with Federal, state, and local emission
regulations. Burners shall be UL approved [mechanical draft burners with all air necessary for
combustion supplied by a blower where the operation is coordinated with the burner] [natural
draft/atmospheric burners]. Burners shall be provided complete with fuel supply system in
conformance with UL 795, ANSI Z21.13 or NFPA 8501.
10-8.2
Hot water boilers, oil fired. Boilers shall be oil fired and shall be designed,
constructed and equipped in accordance with the ASME Boiler Pressure Vessel Code, Section
IV, Heating Boilers. Each boiler shall be of the [firetube] [watertube] [cast iron] type. The boiler
capacity shall be based on the ratings shown in HYI-01 or as certified by the American Boiler
Manufacturers Association. Boiler shall be designed to burn oil. Each boiler shall comply with
