II START UP ADJUSTMENTS
A) Equipment Required
1. CO2 analyzer
2. Draft gauge.
3. Fuel pressure gauge.
4. Stack thermometer.
5. Smoke tester.
B) Burner Adjustments
Allow the burner to operate steadily for at least 15 minutes. Check the burner settings according to the
installer/serviceman label for your model, printed at the end of this manual, and make the following
adjustments:
1.
Sampling Hole
- punch 1/4" hole in the flue between the flue box and the draft regulator. All test
readings should be taken from this point.
2.
In The Stack Draft
- Take a draft reading from the flue pipe sampling hole. Adjust the barometric
draft regulator to -.02" in the stack. In tall chimneys a second draft regulator may be required in the
flue pipe to regulate draft under high draft conditions.
3.
Overfire Draft
- Take a draft reading from the draft port located to the left of the burner. Compare
the readings with those according to the installer/serviceman labels for Series I and II boilers starting
on page 30. Reinstall the draft port plug after all readings have been taken.
4.
Pump Pressure
- Adjust the pump discharge pressure per value on serviceman label.
5.
Combustion Air
- Reduce the air supply to allow just sufficient air for clean combustion. This is
accomplished by loosening the lock screws on the air shutter, and closing the air shutter until a trace of
smoke is recorded. Take a CO2 sample. Open the air shutter lowering CO2 about 1-1/2% to 2%. A zero
smoke reading should result. If this adjustment cannot be obtained, refer to the trouble shooting section
in this manual.
C) Instructing the Homeowner
The care and operation of the boiler should be explained to the homeowner, including care of the
burner, how to adjust the thermostat, necessity of air supply to the burner, and the simple checks to
make before calling the serviceman if the burner fails to operate automatically.
III BURNER SERVICING
A) Burner Components
If a replacement part is necessary, use only the part specified on the burner parts list in this manual.
Specify the part number and description when ordering. (See included burner literature).
B) Nozzles
Use only the correct nozzle specified on the “Installer/Serviceman” decal located on front boiler jacket.
Be extremely careful not to touch the nozzle orifice to avoid scratches or dirt which may cause leaks or
affect the oil spray pattern.
C) Electrode Settings
The electrode setting is critical for proper ignition of the fuel. Check to be sure electrode settings
comply with the specifications.
