At2,000feet,theNFGCrequiresthatthisappliancebe
derated4%foreach1,000feetofaltitude.Forexample,
the input needs to be reduced 8% at 2,000 feet, 12% at
3,000 feet, etc. This furnace can be derated by reducing
the orifice size or decreasing the manifold pressure. When
decreasing the manifold pressure, the pressure must not
besetbelow3.2in.W.C..NOTE: If the pressure needs
tobe set below 3.2 in.W.C.to achievethe proper de-
rate, then change the orifice size and raise the manifold
pressurebackto3.5in.W.C..
OperatingInstructionsforPOOILBurners
OilburnersinPOseriesfurnacesarefactoryequipped
with a primary control capable of either intermittent or
interrupted ignition.
Start-UpProcedure
1. Openallmanualshut-offvalvesintheoilsupplyline
from the tank to the burner.
2. TurnONtheelectricalsupplytothefurnace.
3. Set the room thermostat to the desired temperature.
Air-BleedProcedure-SinglePipeInstallation
1. Openthedoortothefurnace.
2. Attach1/4”I.D.plastictubeovertheendoftheairbleed
valveontheoilpumpasshowninFigure15.Place
the other end of the tube in a large container.
3. Pull the door interlock switch out to start the burner.
4. Turn the airbleed valve open not more than 1/2 turn
togetafastowofoilintothecontainer.
5. To assure continuous operation, use a wire to jump
terminalsT-Tontheprimarycontrolwhileburneris
running. If furnace is equipped with the Honeywell
R7184 or Beckett 7505 primary control, perform the
next3stepstoprimetheoilpump:
a. While the ignition is on, press the reset button for
1/2 second or less and release the reset button.
The lockout time will be extended to 4 minutes.
b. If prime is not established within the 4 minutes, the
control will lock out. Press the reset button to reset
thecontrolandgobacktostep“a”.
c. Repeatsteps“a”&“b”,ifneeded,untilthepumpis
fully primed.
6. Whenoilowisclearofairbubbles,closeair-bleed
valve and tighten. NOTE:Airbleedouttimewillvary
depending on length of oil line, number of bends, etc.
7. Remove the jumper wire on the primary control.

NOTE: If furnace is equipped with the Beckett 7505 primary
control,primetheoilpumpusingthefollowingsteps:
1. Aftertheburnerstarts,pressandholdtheresetbutton
for 15 seconds until the yellow light turns on. This
indicates that the button has been held long enough.
2. Release the reset button. The yellow light will turn off
and the burner will start up again.
3. At burner start up, click the reset button while the
igniter is still on. NOTE: This will transition the control
to a dedicated pump prime mode, during which the
motor, igniter and valve are powered for 4 minutes.
The yellow light will be on. NOTE: If the prime is not
established during the 4 minute pump prime mode,
repeat step 3 until the pump is fully primed.
OilBurnerShutdownProcedure
Settheroomthermostatto“OFF”oritslowestsetting.
FlameAdjustment
1. Set the thermostat below room temperature to start
the furnace.
2. Allowthefurnacetooperateforabout10minutes.
3. Adjusttheairshuttersettinguntil11%CO2 with zero
smoke or less is achieved. NOTE: The draft over the
remustbeatleastnegative0.02in.W.C.Thefactory
setairshuttersettingsareshowninTable7(page21).
Electrode Setting
Theelectrodesettingiscarefullysetatthefactory.However,
during transit, the setting of the electrodes may become
improper. Before attempting to start the oil burner, check
the positioning of the electrodes to ensure that they are
properly positioned, as shownin Figure 16 (page 23).
Improperly adjusted electrodes can result in poor ignition.
Donotpermittheelectrodestobecloserthan¼”toany
grounded surface.
Switching from Interrupted to intermittent Ignition
Control

between interrupted and intermittent ignition control. To
switchfrominterruptedduty(Factoryset)tointermittent
duty,removetheblueignitorwirefromthequick-connect
