Install Instructions

14
This burner is shipped with the oil pump set
to operate on a single line system. To operate
on a two-line system the bypass plug must be
installed.
WARNING: DO NOT operate a single
line system with the by-pass plug installed.
Operating a single line system with the by-pass
plug installed will result in damage to the pump
shaft seal.
Note: Pump pressure was factory pre-set but
must be checked at time of burner start-up. A
pressure gauge is attached to the PRESSURE/
BLEEDER PORT (7) for pressure readings.
Two PIPE CONNECTORS (4) are supplied
with the burner for connection to either a single
or two-line system. Also supplied are two
ADAPTORS (3), two female ¼” NPT to adapt
oil lines to burner pipe connectors. All pump
port threads are British Parallel Thread design.
Direct connection of NPT threads to the pump
will damage the pump body.
Riello manometers and vacuum gauges DO
NOT require any adapters, and can be safely
connected to the pump ports. An NPT x metric
adapter must be used when connecting other
gauge models.
h. Replace Burner Cover and Tighten Burner Cover
Screws.

4. On the Carlin EZ-PH Burner, use the following
procedure to complete the inspection, check the
settings and to change the nozzle to a lower ring
rate:
a. Loosen two (2) igniter latching screws, rotate
tabs and swing open igniter about hinge.
b. Loosen knurled nut and disconnect copper
connector tube.
c. Remove nozzle line electrode assembly from
burner.
d. If high ring rate is desired, conrm the nozzle
is the proper size and type, refer to Table 14C (at
rear of this manual), then proceed to Item i.
e. If a lower input is desired, remove the ame
retention head and then remove the nozzle that
was factory installed.
f. Locate the desired nozzle, refer to Table 14C
(at rear of this manual) for proper nozzle. The
nozzle must be securely installed to assure leak
free joints between the nozzle and adapter.
When installing the nozzle, be careful not to
bump or move the burner electrodes.
g. Reinstall Flame Retention Head on Nozzle Line
Electrode Assembly. Make sure the clamp is
fully sated against the shoulder on the nozzle
adapter before securing.
h. Loosen and remove the retaining nut and factory
installed head bar from side of burner housing.
Install the proper head bar that corresponds to
the desired ring rate, refer to Table 14C (at rear
of this manual), and tighten retaining nut.
i. Readjust air band to preliminary setting that
corresponds to the lower ring rate nozzle
installed, refer to Table 14C (at rear of this
manual).
j. Inspect and measure burner electrodes. Refer to
Figure 10 for proper electrode setting. Readjust
electrode setting to the proper dimensions if
necessary.
