8.Light Oil Control Systems:

LF (FALFS): On-off operation, fixed air, reduced fuel low fire start, high fire run. Single-position air, two-position oil.

L (LHO):	On-off operation, low fire start, high fire run. Two-position air, two-position oil.
H (LHL):	Low-high-low-off firing conditions. Two-position air, two-position oil.
M (MOD):	On-off operation, with proven low fire start and full modulating firing conditions. Proportional motor drives fuel metering valve and combus-
	tion air damper according to the firing conditions. Fixed damper pre-purge on 488-1088R, open damper pre-purge on 1088-1888.

9.Gas/Light Oil Control Systems:

A/LF (OO/FALFS): Combines gas and light oil characteristics listed above.

L/L (LHO/LHO):	Combines gas and light oil characteristics listed above.
H/H (LHL/LHL):	Combines gas and light oil characteristics listed above.

M/M (MOD/MOD): Combines gas and light oil characteristics listed above.

10.120/60/1 control circuit is used for all burners.

11.Control circuit transformer is available as an option.

12.Motor starter contact will be furnished for all units.

13.Combustion Controls:

a)R8184G combustion control uses cadmium cell for flame detector to monitor oil burner flame, also furnishes intermittent ignition.

b)RM7897 flame safeguard control uses ultraviolet electronic flame detector to monitor gas or oil burner flame and provides pre-purge programming. “A” models provide intermittent pilot; “C” models provide interrupted pilot and RUN/TEST switch.

c)RM7840M, E110/EPD390 flame safeguard control monitors the oil or gas burner flame, provides pre-purge and post-purge programming. Timed low fire start is provided by means of timing built into control. Control is used with UL on-off (low fire start) systems. Ultraviolet sensitive electronic flame detector is standard with infrared detector available.

d)RM7840L, E110/EPD170 flame safeguard control monitors the oil or gas burner flame, provides pre-purge and post-purge programming, provides switch- ing necessary to allow firing rate motor to be driven to both low fire and high fire positions, prevents start-up if pre-ignition interlocks are open and has low fire start proving circuit. In the event pre-ignition interlock circuit or running interlock circuit does not “prove”, system will lock out on safety. Ultraviolet sensitive electronic flame detector is standard with infrared detector available.
