VENTILATION AND COMBUSTION AIR
Appliances shall be installed in a location where the
facilities for ventilation permit satisfactory combustion
of oil, proper venting and the maintenance of ambient
temperature at safe limits under normal conditions of
use. Applications shall be located in such a manner as to
not interfere with proper circulation of air within the
confined space. When building are so tight that normal
infiltration does not meet air requirements, outside air
shall be introduced. Ducts used to convey air from the
outdoors shall be of the same cross-sectional area as the
free area of the opening to which they connect. The
minimum dimensions of rectangular air ducts shall be
not less than 3 inches (76 mm). See Table 10 for
information on round duct sizing.
For residence-type installations and similar usages, the
requirements normally may be obtained by application
of one of the methods shown in Figures 8 through 11
following.

BURNER NOZZLE AND ELECTRODE
ADJUSTMENTS
Check nozzle size as to conformance to installation
requirements. Install nozzle by screwing into hexagon
adapter. Refer to recommended start-up setting in
Table 9.
SPACING OF ELECTRODES
The electrodes should be spaced 5/32” apart. They
should extend 1/16” beyond the end and 5/16” above
the center of the nozzle tip as shown in Figure 7
GUN ASSEMBLY ADJUSTMENT
The gun assembly can be adjusted in the slot inside of
fan housing by loosening screw holding slot cover in
position. Nozzle tip should ordinarily be located 1-1/8”
behind the front face of the cone.
REMOVING GUN ASSEMBLY
Disconnect the oil line at the fan housing and remove
lock nuts on copper tube fitting. Loosen igniter hold
down clamps, then swing igniter up and backward. Gun
assembly can now be removed through this opening.
