GROUND SHIELD TO SUBBASE EARTH GROUND SCREW ON LOW VOLTAGE SIDE OF SUBBASE.

FUSE LINE VOLTAGE TO CONTROL SYSTEM WITH TYPE SC15 FUSE OR FUSE LIMIT INPUT WITH

TYPE SC5 FUSE.

RS-485 DDL CONNECTOR IS ON R7999 CONTROLLER.

MUST USE APPROVED FUEL SELECT SWITCH (CENTER OFF POSITION).

NORMALLY OPEN MOMENTARY SWITCH (CONNECTION BETWEEN TERMINALS 35 AND 38).

MANUAL FIRING RATE POTENTI0METER (CONNECTION BETWEEN TERMINALS 36 AND 38).

120 VAC RELAY, WITH NORMALLY CLOSED CONTACT WIRED INTO LINE FROM 7800 SUBBASE

TERMINAL 9 AND R7999 SUBBASE TERMINAL 11. NOTE: THIS RELAY IS NEEDED FOR VPS

APPLICATION SELECTIONS IF BEFORE, SPLIT, OR BOTH ARE CHOSEN. IT IS NOT REQUIRED

WHEN AFTER IS SELECTED.

AN ADDITION TO THE FUEL CHANGEOVER SWITCH TO ALLOW THE 7800 TO OPERATE THE

VPS FEATURE WHEN FIRING ON GAS AND TO OPERATE THE FUEL VALVES WHEN ON OIL.
