Pilot Valve /First Stage Oil Valve (Valve/Start) Terminal 21.

A 30 second MFEP can be accomplished by adding a jumper wire between Terminals 19 and 5.

SERVICE NOTE:Clipping and removing a site-configurable jumper enhances the level of safety.  Removal after 200 hours of 

main valve operation will result in a hard lockout, Code 110.

After checking all wiring, perform this checkout before 

installing the RM7800/RM7840 on the subbase. These tests 

verify the Q7800 Wiring Subbase is wired correctly, and the 

external controllers, limits, interlocks, actuators, valves, 

transformers, motors and other devices are operating 

properly. 

1. Close all manual fuel shutoff valve(s) before starting 

these tests. 

2. Use extreme care while testing the system. Line 

voltage is present on most terminal connections 

when power is on.

3. Open the master switch before installing or 

removing a jumper on the subbase. 

4. Before continuing to the next test, be sure to 

remove test jumper(s) used in the previous test. 

5. Replace all limits and interlocks that are not 

operating properly. Do not bypass limits and 

interlocks.

Internal surge protectors can break down and conduct 

a current, causing the RM7800/RM7840 to fail the 

dielectric test or possibly destroy the internal lightning 

and high current protection. Do not perform a dielectric 

test with the RM7800/RM7840 installed.

1. Voltmeter (1M ohm/volt minimum sensitivity) set on the 

0-300 Vac scale. 

2. Two jumper wires; no. 14 wire, insulated, 12 inches 

(304.8 mm) long with insulated alligator clips at both 

ends. An ammeter may be used in place of a jumper 

wire to check the amp usage when testing the blower 

motor, ignition, pilot and main valve operation.

1. Perform all applicable tests listed in Static Checkout, 

Table 8, in the order listed. 

2. Make  sure all manual fuel shutoff valve(s) are closed.

3. Perform only those tests designated for the specific 

RM7800/RM7840 model being tested. 

4. Raise the setpoint of the operating controller to simulate 

a call for heat. 

5. For each test, open the master switch and install the 

jumper wire(s) between the subbase wiring terminals 

listed in the Test Jumpers column.

6. Close the master switch before observing operation. 

7. Read the voltage between the subbase wiring terminals 

listed in the Voltmeter column.

8. If there is no voltage or the operation is abnormal, check 

the circuits and external devices as described in the last 

column. 

9. Check all wiring for correct connections, tight terminal 

screws, correct wire, and proper wiring techniques. 

Replace all damaged or incorrectly sized wires. 

10. Replace faulty controllers, limits, interlocks, actuators, 

valves, transformers, motors and other devices as 

required. 

11. Make sure normal operation is obtained for each 

required test before continuing the checkout. 

12. After completing each test, be sure to remove the test 

jumper(s). 

Make sure all manual fuel shutoff valves are closed 

before performing static checkout.
