See Figs. 1 and 2 for location of component parts and see
Figs. 7 and 8 or Q7800 Specifications for terminal locations.
PRELIMINARY INSPECTION
Perform the following inspections to avoid common
problems. Make certain that:
1. Wiring connections are correct and all terminal
screws are tight.
2. Flame detector(s) is clean, installed and positioned
properly. Consult the applicable Instructions.
3. Correct combination of amplifier and flame detec-
tor(s) is used. See Table 2 in the Specifications.
4. Plug-in amplifier and purge card are securely in place.
5. Burner is completely installed and ready to fire; con-
sult equipment manufacturer instructions. Fuel lines are
purged of air.
6. Combustion chamber and flues are clear of fuel and
fuel vapor.
7. Power is connected to the system disconnect switch
(master switch).
8. Lockout switch is reset (push in reset pushbutton)
only if the RM7895 is powered, see Figs. 1 and 2.
9. Run/Test Switch is in RUN position (RM7895C,D).
10. System is in the STANDBY condition. POWER
LED is energized.
11. All limits and interlocks are reset.

WARNING
Do not allow fuel to accumulate in the combus-
tion chamber. If fuel is allowed to enter the
chamber for longer than a few seconds without
igniting, an explosive mixture could result. It is
recommended that you limit the trial for pilot to
ten seconds, and limit the attempt to light the
main burner two seconds from the time the fuel
has reached the burner nozzle. In any case, do
not exceed the nominal lightoff time specified
by the equipment manufacturer. Close the
manual fuel shutoff valve(s) if the flame is not
burning at the end of the specified time.
CAUTION
1. Use extreme care while testing the system.
Line voltage is present on most terminal con-
nections when power is on.
2. Open the master switch before removing or
installing the RM7895.
3. Make sure all manual fuel shutoff valve(s) are
closed before starting the initial lightoff check
and the Pilot Turndown tests.
4. Do not put the system in service until you have
satisfactorily completed all applicable tests in
this section and any others required by the
equipment manufacturer.
CAUTION
If an RM7895 is replaced with a lower or higher
functioning 7800 SERIES Relay Module, the
burner will not sequence unless wiring changes
are made.
IMPORTANT:
1. If the system fails to perform properly, refer to 7800
SERIES System Annunciation Diagnostics and
Troubleshooting, form 65-0118.
2. Repeat ALL required Checkout tests after all adjust-
ments are made. ALL tests must be satisfied with the
flame detector(s) in its FINAL position.
EQUIPMENT RECOMMENDED
Volt-ohmmeter (20 kohm/volt minimum sensitivity):
• 0-300 Vac capability.
• 0-6000 ohm capability.
• 0-10 Vdc capability.
