Steam Boilers Only
Steam boilers must use the lower input nozzle.
The lower input nozzle will provide greater
boiler effi ciency and for steam boilers, reduce
boiler corrosion. However, boiler output will be
reduced.
Burners for knockdown V83 - V86 steam boilers
are shipped with the lower (standard) fi ring rate
nozzle installed. Knockdown V87 - V89 boilers
are provided with one nozzle, installed in the
burner, that provides the same fi ring rate as the
water boiler of the same size.
a. Installation/Removal of Drawer Assembly
i.
Loosen screws, rotate latches and swing
open the transformer.
ii. The combustion head assembly can be
removed with the blower wheel access cover
in place or removed. If the access cover is
removed, the head assembly will not have to
be rotated.
Disconnect the fl ared fi tting to the oil line
and remove the aluminum thumb-nut from
the nozzle line. Remove the combustion
head assembly from the air tube. Rotating
the assembly upside down will ease
removal.
iii. Loosen the clamp screw on the retention
ring assembly and slide the retention ring off
the adaptor.
Install and tighten the proper nozzle in
the adaptor. See Table 6 of this manual.
Be careful not to damage the electrode
insulators or to bend the wires.

b. Combustion Head Positioning Bars
iv. Replace the retention ring assembly, slipping
one of the riveted arms through the 1/8-inch
gap between the electrode tips. This arm
should be straight up. Also, be sure that
the retention ring clamp is tight against the
shoulder on the adaptor. Then tighten the
clamping screw.
v.
Check the electrode settings specifi ed as
follows and shown in Figure 27C. 1/8-inch
gap, 1/4 to 5/16-inch above the nozzle
centerline, and fl ush to 1/16-inch ahead of
the nozzle tip.
vi. Re-install the combustion head assembly
holding it upside down while inserting
into the housing. The fl ame retention ring
end of the assembly must be lifted and
guided through the throttle cone (a reduced
diameter) in the end of the air tube. DO
NOT FORCE IT.
vii. After attaching the proper positioning bar,
refer to Paragraph 7,b, run the thumb-nut
onto the nozzle line and tighten it lightly.
Connect the fl ared fi tting on the copper oil
line to the nozzle line and tighten.
i.
The Elite EZ-1HP and EZ-2HP burners are
supplied with the proper positioning bar
installed onto the housing that matches the
high (standard) input oil nozzle installed in
the burner. A second positioning bar and
nozzle for the lower (minimum) fi ring rate
is shipped loose for the V83-V86 models,
attached the burner.
Verify that the installed positioning bar
matches the high input oil nozzle installed
in the burner or replace them both with the
nozzle and positioning bar that matches
the lower fi ring rate, refer to Table 6 of this
manual.
The remaining bar(s) should be placed in
the rear of the housing or junction box for
future use in the event the fi ring rate must be
changed.
In the case of the EZ-1HP, the proper head
positioning bar is still matched by the size
of the nozzle, not the input. For example, if
nozzle size is 0.75 GPH, input @ 150 psi is
approximately 0.90 GPH and the proper bar
is 0.75 GPH.
ii. Model EZ-1HP Positioning Bars: 0.50
GPH, 0.60-0.65 GPH, 0.75 GPH, 0.85-1.00
GPH, 1.10-1.25 GPH, 1.35-1.50 GPH, 1.65
GPH.
iii. Model EZ-2HP Positioning Bars: 1.50
GPH, 1.65-1.75 GPH, 2.00 GPH, 2.25 GPH.
