1 Fuel input shall be determined by one of the following:
- The burner input shall not exceed the input shown on the burner nameplate or as otherwise identified by the manufacturer.
- The nominal boiler rating, as determined by the building official, plus 25 percent.
2 Automatic boilers shall have one name failure device on each burner, which shall prove the presence of an ignition source at the point where it will ignite
the main burner, except that boiler groups A, B, E, F, and G, which are equipped with direct electric ignition, shall monitor the main burner, and boiler groups
using interrupted pilots shall monitor the main burner after the prescribed limited trial and ignition periods. Boiler group A, equipped with continuous pilot,
shall accomplish 100 percent shutoff within 90 seconds upon pilot flame failure. The use of interrupted pilots in boiler group C is limited to approved burner
units.
3 In boiler groups B, C, and D a 90 second main burner flame failure limit shall be permitted to be applied where continuous pilots are provided on manufacturer
assembled boiler-burner units that have been approved by an approved testing agency in accordance with nationally recognized standards approved by
the building official. Boiler groups F and G equipped to re-energize their ignition systems within 0.8 second after main burner flame failure will be permitted
30 seconds for group F or 15 seconds for group G to re-establish their main burner flames.
4 Boiler groups C and D shall have controls interlocked to accomplish a non-recycling fuel shutoff upon high or low gas pressure, and boiler groups F, G, and
H using steam or air for fuel atomization shall have controls interlocked to accomplish a non-recycling fuel shutoff upon low atomizing steam or air pressure.
Boiler groups F, G, and H equipped with a preheated oil system shall have controls interlocked to provide fuel shutoff upon low oil temperature.
5 Automatic boilers shall have controls interlocked to shut off the fuel supply in the event of draft failure where forced or induced draft fans are used or, in the

means of creating air movement or an oil burner that obtains two-thirds or more of the air required for combustion without mechanical means of creating air
movement shall not require purge by means of four air changes, so long as its secondary air openings are not provided with means of closing. Where such

approved testing agency. An automatic hot-water heating, power boiler, and package hot-water supply boiler shall be equipped with one low-water level

without draining the heating system, except on boilers used in Group R Occupancies of less than six units and in Group U Occupancies and further, except
that the low-water level limit control is not required On package hot-water supply boilers approved by a nationally recognized testing agency. However, a low-water
flow limit control installed in the circulating water line shall be permitted to be used instead of the low water level limit control for the same purpose
on coil-type boilers.
9 An automatic low-pressure steam-heating boiler, small power boiler, and power steam boiler shall be equipped with two high-steam pressure limit controls
interlocked to shut off the fuel supply to the main burner with manual reset on the control, with the higher setting and two low-water-level limit controls, one
of which shall be provided with a manual reset device and independent of the feed water controller. Coil-type flash steam boilers shall be permitted to use
two high-temperature limit controls, one of which shall be manually reset in the hot water coil section of the boiler instead of the low-water level limit control.
10 Boiler groups C, D, and H shall use an approved automatic reset safety shutoff valve for the main burner fuel shutoff, which shall be interlocked to the programming control devices required. On oil burners where the safety shutoff valve will be subjected to pressures in excess of 10 psi (69 kPa) where the burner is not firing, a second safety shutoff valve shall be provided in series with the first. Boiler groups C and D using gas in excess of 1 psi (7 kPa) pressure or having a trapped combustion chamber or employing horizontal fire tubes shall be equipped with two approved safety shutoff valves, one of which shall be an automatic reset type, one of which shall be permitted to be used as an operating control, and both of which shall be interlocked to the limit-control devices required. Boiler groups C and D using gas in excess of 1 psi (7 kPa) pressure shall be provided with a permanent and ready means for making periodic
tightness checks of the main fuel safety shutoff valves.
11 Control and limit device systems shall be grounded with operating voltage not to exceed 150 volts, except that, upon approval by the building official, existing
control equipment to be reused in an altered boiler control system shall be permitted to use 220 volts single phase with one side grounded, provided such voltage
is used for all controls. Control and limit devices shall interrupt the ungrounded side of the circuit. A readily accessible means of manually disconnecting the
control circuit shall be provided with controls so arranged that where they are de-energized, the burner shall be inoperative.
A steam boilers shall be provided with a pressure
gauge and a water level glass. A water boilers shall be
provided with a pressure gauge and a temperature gauge.
