2. Burner Adjustments
Allow the burner to operate steadily for at least 15 minutes. Check the burner settings according
to the installer/serviceman labels for Series I and II boilers at the end of this manual, and make
the following adjustments:
a.
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.
b.
In The Stack Draft
- Take a draft reading from the flue pipe sampling hole. Adjust the baro-
metric 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.
c.
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.
d.
Pump Pressure
- Adjust the pump discharge pressure per value on serviceman label.
e.
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 trou-
ble shooting section in this manual.
f.
Stack Temperatures
- Check to see that the stack temperature is according to the installer/ser-
viceman labels for Series I and II boilers starting on page 30.
3. 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.
C) BURNER SERVICING
1. Burner Components
If a replacement part is necessary, use only the part specified on the burner parts list in this man-
ual. Specify the part number and description when ordering. (See included burner literature).
2. 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 effect the oil spray pattern.
3. Electrode Settings
The electrode setting is critical for proper ignition of the fuel. Check to be sure electrode settings
comply with the specifications.
4. Fan and Blower Housing
The fan and blower housing should be kept clean from lint and dirt. If the boiler is located near
an unvented dryer, special care must be taken so that lint does not block air passages in the burn-
er and proper combustion air is provided.
