Notes for Table 3

1. Combustion Controls:

R7184P

Uses cadmium cell for flame detector to monitor oil burner flame, also furnishes intermittent ignition.

RM7897A, RM7897C

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. RM7897 provides same as above with

 

 

 

 

 

post-purge.

RM7840L, E110/EPD170

Monitors the oil or gas burner flame, provides pre-purge and post-purge programming, provides switching 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.

RM7800L, E110/EP160

Monitors the oil or gas burner flame with digital readout control system, provides pre-purge and post-purge programming,

 

 

 

 

 

provides switching necessary to allow firing rate motor to be driven to both low fire and high fire position, 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.
