*Gas burners shall be of the forced draft multi-jet type suitable for burning gas with heat content of ___________ BTU per

cubic foot and specific gravity of ( ___________ inches w.c.) ( ___________ psig). Burner shall be complete with integral

motor driven blower, ignition assembly, combustion safeguard, motor starter, complete gas train, including gas pressure

regulator and dual gas valves, and all necessary controls for safe and efficient operation in accordance with UL require-

ments (and FM requirements) (and IRI requirements).

Note: Insert additional details such as desired combustion safeguard, firing sequence, and/or other features to meet proj-

ect requirements.

*Combination gas/oil burner shall consist of an integral assembly of a forced draft pressure atomizing oil burner suitable

for burning No.2 oil and a forced draft multi-jet type gas burner suitable for burning ___________ gas with a heat content

of ___________ BTU per cubic foot and specific gravity of___________ delivered to the gas train inlet at a pressure of (

___________ inches w.c.) ( ___________ psig). Burner shall be complete with integral motor driven blower, oil pump, oil

nozzle(s), oil solenoid valve(s), ignition assembly, combustion safeguard, motor starters, complete gas train including gas

pressure regulator and dual gas valves, and all necessary controls for safe and efficient operation in accordance with UL pressure regulator and dual gas valves, and all necessary controls for safe and efficient operation in accordance with UL

requirements (and FM requirements) (and IRI requirements). Changeover to either fuel shall be by means of a manual se-

lector switch which shall energize only those circuits necessary to provide the appropriate timing and sequence of events

for the fuel selected, except that the oil pump may continue to operate when firing gas. No burner adjustments or re-posi-

tioning of control linkage shall be required when changing from one fuel to the alternate fuel.

Note: Insert additional details such as desired combustion safeguard, firing sequence, and/or other features to meet proj-

ect requirements.

*Combination gas/oil burner shall consist of an integral assembly of a forced draft low pressure air atomizing oil burner

suitable for burning (No.2 oil) (No.4 oil) (No.5 oil) (No.6 oil) and a forced draft multi-jet gas burner suitable for burning

___________ gas with a heat content of ___________ BTU per cubic foot and specific gravity of ___________ delivered

to the gas train inlet at a pressure of ( ___________ inches w.c.) ( ___________ psig). Burner shall be complete with inte-

gral motor driven blower, air compressor, oil supply pump, atomizing assembly, ignition assembly, combustion safeguard,

motor starters, complete gas train including gas pressure regulator and dual gas valves, and all necessary controls for motor starters, complete gas train including gas pressure regulator and dual gas valves, and all necessary controls for

safe and efficient operation in accordance with UL requirements (and FM requirements) (and IRI requirements). Change-

over to either fuel shall be by means of a manual selector switch which shall energize only those circuits necessary to pro-

vide the appropriate timing and sequence of events for the fuel selected, except that the oil pump may continue to operate

when firing gas. No burner adjustments or repositioning of control linkage shall be required when changing from one fuel

to the alternate fuel.

Note: Insert additional details such as desired combustion safeguard, firing sequence, and/or other features to meet proj-

ect requirements.

9. Electrical supply to the boiler(s) will be ___________ volts ___________ hz ___________ phase. All control circuits

shall be 120 volts, 60 hz, 1 phase, with all switches in the ungrounded leg. Fuse protection for the control circuit shall be

provided.
