SECTION 14 PRIMING THE FUEL PUMP CONTINUED
14.11 Observe the end of the fuel supply line that is disconnected from the
burner. Allow a steady stream (no air bubbles) of fuel to flow into the
container for several minutes. This will flush any debris from the fuel line
that could potentially plug the nozzle. The vacuum gauge reading should
not exceed 5” HG of vacuum.
14.12 Turn the room thermostat below room temperature or “OFF”. The fuel
supply pump will now stop.
14.13 Reconnect the fuel supply line to the burner.
14.14 Remove the jumper wire from the F-F terminals on the oil primary control,
reattach the yellow cad cell wires.
14.15 Adjust the burner air filter/regulator to 17 PSI.
14.16 If the fuel supply pump prime, or fuel stream has air in it (spurting,
fluctuating flow) there is likely a leak in the suction side of the plumbing.
Refer to section 17, trouble-shooting, flow chart #2. The burner should
now be ready to fire. Return to section 13, 13.12.
