Start-Up And Adjustment Of Oil Burner

NOTE: Bacharach or Dwyer test kits include these 

instruments.

(See oil burner instructions for nozzle and electrode setting)

1. 

Verify oil burner nozzle is tight in adapter. Burner 

mounting bolts should be tight.

2. 

Check electrode setting, may have been jarred out of 

position during transportation.

3. 

Lubricate burner motor if necessary.

4. 

Set room thermostat to call for heat, or jump 

thermostat contacts on boiler control.

5. 

Open all oil line valves.

6. 

Turn service switch on. Burner will start.

7. 

On one pipe fuel systems only, bleed pump as soon as 

burner starts. Allow oil to run until all traces of air in 

suction line disappear.

8. 

Turn “OFF” burner and install pressure gauge port on 

pump.

9. 

Start burner and check oil pressure for 140 psi adjust if 

necessary.

NOTES:
Information in above table uses Beckett model AFG burner for both model numbers OBC-3 and OBC-4.
OBC4115 is rerated boiler which requires rerate kit.

Check safety control circuit

 after burner adjustments 

have been made for satisfactory  performance.

A.  High limit control: remove cover and note 

temperature setting. 

See  Figure 20, Page 17 

. With 

burner operating, decrease setting to minimum 

point.  When boiler water temperature exceeds set 

point, high limit switch will open, shutting off power 

to oil burner.  Return setting to desired high limit 

point.  Burner should start. 

B. Verify Primary Control and Flame Sensor -

• Flame Failure

 - simulate by shutting off oil supply 

with hand valve while burner is on. Sixty seconds after  

fl

 ameout, safety switch locks out, ignition stops, motor 

stops and oil valve - when used - closes. To restart, 

open oil supply valve and reset safety switch.

• Ignition Failure

 - With burner off, close oil supply 

valve and run through start-up procedure. Safety 

switch should lock out as in 

fl

 ame failure.

• Power Failure

 - Turn off main power supply switch 

while burner is operating. When burner stops, restore 

power and burner should start. If operation is not as 

described as above, check wiring and controls.

OPERATING INSTRUCTIONS

Burner Operation Instructions

• Use provided ¼" diameter slot in inspection cover plate 

to take draft readings in combustion chamber. 

See 

 Figure 20, Page 17 .

• Drill  ¼" diameter hole in 

fl

 ue pipe between boiler and 

barometric damper (if used) to take draft, CO

2

, smoke 

and temperature readings. Plug hole when done.

• Adjust air shutter on oil burner to obtain “trace” of 

smoke. Measure CO

at this point. 

• Increase air adjustment to lower CO

approximately one 

percent. 

• Verify minimum negative .02 w.c., (water column), 

“over

fi

 re” draft and zero smoke. 

• If -.02 w.c. “over

fi

 re” draft can not be maintained, 

changes and/or modi

fi

 cations may be required in venting 

or chimney.

• See table below as guideline for initial start-up. Make 

fi

 nal adjustments using combustion instruments.

 WARNING

Boiler and venting installations shall be performed 

by a quali

fi

 ed expert and in accordance with the 

appropriate manual. Installing or venting boiler 

or other gas appliance with improper methods or 

materials may result in serious injury or death due 

to 

fi

 re or to asphyxiation from poisonous gases such 

as carbon monoxide with is odorless and invisible.
