BURNER SETUP AND ADJUSTMENT
PROCEDURES
All oil burner installations should be performed by a
qualified installer in accordance with regulations of the
National Fire Protection Standard for Oil-Burning
Equipment, NFPA31 -- latest edition, and in complete
compliance with all local codes and authorities having
jurisdiction. A qualified installer is an individual or
agency who is responsible for the installation and
adjustments of the heating equipment and who is
properly licensed and experienced to install oil-burning
equipment in accordance with all codes and ordinances.
The proper installation and adjustment of any oil burner
requires technical knowledge and the use of combustion
test instruments. The following procedure must be
followed to correctly adjust the burner to match the
specific characteristics of the installation.
IMPORTANT
Always use combustion test instruments when
making burner adjustments and draft gauge
when setting the barometric damper. It is
virtually impossible to make accurate and
reliable adjustments using the “eyeball”
method.
Check all oil lines and connections for leaks.
Connect pressure gauge by removing bleed fitting and
screwing in pressure gauge. See Figure 9.

PREPARATION STEPS
A. Calibrate and Check Operation of
Measuring Equipment Follow
manufacturer’s recommended procedures for
calibration and equipment check out.
B. Prepare Heating Unit for Testing Drill two
1/4 inch holes in the flue between the heating
plant and the barometric draft regulator. If
space permits, the holes should be located in a
straight section of the flue, at least two flue
diameters from the elbow in the flue pipe and at
least one diameter from the draft regulator. The
purpose of the two holes in the flue pipe is to
speed up testing and reduce instrument
handling.
C. Clean and Seal Heating Plant Make sure the
burner blast tube, fan housing, and blower
wheel are clear of dirt and lint. Seal any air
leaks into the combustion chamber.
D. Nozzle Inspection Annual replacement of
nozzle is recommended. The nozzle size
should match the design load . DO NOT
OVERSIZE. (Determination of oversizing can
be determined prior to your adjustment. If the
firing rate should be reduced refer to Table 4.)
Short cycles and low percent :on: time result in
higher overall pollutant emissions and lower
thermal efficiency. An in-line oil filter will
reduce service problems due to nozzle clogging.
