CF1400/CF2300 Burner Manual
Initial Air Settings
If your burner was built for a specifi c OEM (Original
Equipment Manufacturer) application, the “Mfr’s
Settings” label (see Figure 1) will indicate the application
and the initial air settings made at Beckett. Please verify
those settings using the following procedure.
If your burner was not built for a specifi ed application,
the following steps outline the procedure for initially
setting the damper (these settings may be different from
settings specifi c to a particular OEM).
Refer to Figure 17 and Tables 4a or 4b, for this
procedure.

Remove the cover screw (A) then the cover (B) and
set aside.
Push in on pin (B) to disengage the motor from the
damper shaft and cam stack. Rotate the damper
shaft by hand to place the adjustment cams in a
position where their adjustment scale can be easily
seen. Release pin (G) to secure the damper shaft
and cam stack to the motor.
Using the wrench (C) supplied with the damper
motor, adjust the blue low fi re cam (D) to the initial
setting listed in Table 4.
Using the same wrench, adjust the red high fi re
cam (H) to the initial settings listed in Table 4.
To adjust the high fi re transition, use a small straight
edge screwdriver. Turn the white adjustment screw
located in the orange transition cam (J) until the
cam indicator is half way between the high and low
settings on the scale.
After setting all the cams, make sure the damper
shaft and cam stack is set between its low fi re
setting and its high fi re setting. (If you don’t it may
not move when it is powered.) Push in pin (G),
move the damper by hand so that notch (E) is
between the low fi re setting and high fi re setting
on scale (F), then release pin (G) to re-engage the
motor. When the motor is powered it will go to its
low fi re setting.

This initial setting should be adequate for starting the
burner at low fi re. Once the burner is in operation,
the air setting will be adjusted for best performance as
discussed later in this manual. Don’t forget to re-install
the cover after all adjustments have been made.

Set Appliance Limit Controls
Set the appliance limit controls in accordance with
the appliance manufacturer’s recommendations.
Move the low-fi re hold switch (not shown) to the low
fi re hold position. This will hold the burner in low fi re
during initial start-up.

Prepare the Fuel Unit for Air Venting
To vent air from one-pipe oil systems, attach a clear
hose to the vent plug on the fuel unit. Provide a
container to catch the oil. Loosen the vent plug.
Vent the air as described under ‘Start the Burner’.

The damper plate is attached
by screws to its shaft, and bears
by screws to its shaft, and bears
against a fl at on the shaft for alignment. The shaft is
secured to the damper motor by a sleeve coupling with
two setscrews bearing against the damper shaft and two
more against the motor shaft. The motor shaft has a
fl at matching the one on the damper shaft. The fl ats on
the damper shaft and the motor shaft should be aligned
so that the position indicator in the damper motor reads
accurately. The best way to align the fl ats is to tighten
the set screws that bear against the fl ats on the shafts
fi rst, and then tighten the ones that bear against the
secured to the damper motor by a sleeve coupling with
two setscrews bearing against the damper shaft and two
more against the motor shaft. The motor shaft has a
fl at matching the one on the damper shaft. The fl ats on
the damper shaft and the motor shaft should be aligned
so that the position indicator in the damper motor reads
accurately. The best way to align the fl ats is to tighten
the set screws that bear against the fl ats on the shafts
fi rst, and then tighten the ones that bear against the
round surface of the shafts afterward.
The test for proper alignment is to disengage the damper
motor from its shaft using the disengaging pin (Item G in
Figure 17) and rotate the damper plate to its full closed
position. The position indicator should point to 0° within
+ 5° tolerance.
